Methods： A total of 85 high-risk patients with obstructive BPH underwent PVP with an 80 W potassium-titanyl-phosphate laser, which was delivered through a side-deflecting fiber with a 23 Fr continuous flow cystoscope. Operative time, blood loss, indwelling catheterzation, international prostate symptom score （IPSS）, quality of life score （QoL）, uroflowmetry, postvoid residual urine volume and short-term complication rates were evaluated for all patients. Results： All patients got through the perioperative period safely. The chief advantages of PVP were： short operative time （25.6 ± 7.6 min）, little bleeding loss （56.8 ± 14.3 mL） and short indwelling catheterization （1.6 ± 0.8 d）. The IPSS and QoL decreased from （29.6 ± 5.4） and （5.4 ± 0.6） to （9.5 ± 2.6） and （1.3 ± 0.6）, respectively. The vast majority of patients were satisfied with voiding outcome. The mean maximal urinary flow rate increased to 17.8 mL/s and postvoid residual urine volume decreased to 55.6 mL. These results are significantly different from preoperative data （P 〈 0.05）. No patient required blood transfusion or fluid absorption. There were few complications and very high patient satisfaction after operation. Conclusion： PVP has a short operative time and high tolerance, and is safe, effective and minimally invasive for high-risk patients, therefore it might be considered as a good alternative treatment for high-risk patients with obstructive urinary symptoms as a result of BPH.展开更多

Patient and Methods: The study was conducted in Department of General Surgery in Maulana Azad Medical College, New Delhi. 60 men with proven clinical diagnosis of BPH of size 30 grams and less presenting with symptoms of bladder outlet obstruction (BOO) were randomised prospectively to undergo either of the two operative modalities. Preoperatively size of the prostate, symptom scoring (IPSS), peak flow rate (Qmax) were assessed. Postoperatively and during 4 months follow up the following data were collected—operative time, catheterisation period, hospital stay, blood loss, Qmax and IPSS. Results: Preoperative parameters in both the groups showed no statistically significant differences with respect to prostate size, Qmax and IPSS Scoring. At 4 months follow up Qmax increased from (6.35 ± 4.49) to (16.41 ± 2.28) in TURP group and (4.51 ± 3.57) to (15.95 ± 2.58) in BNI group. IPSS decreased from 18.70 to 5.7 in TURP group and 18.90 to 6.00 in BNI group. All differences were statistically significant. There was a statistically significant difference in operative time, blood loss, hospital stay, catheterisation timing favouring BNI. Conclusion: TURP and BNI are equally effective in providing symptomatic improvement. BNI has an upper hand in reference to operative time, hospital stay, duration of catheterisation and blood loss.展开更多

Blood loss is one of the most common complications of TURP. Objective: To evaluate the effect of preoperative dutasteride on bleeding related to TURP in patients with BPH. Materials and Methods: This prospective interventional study was done in the department of urology, Dhaka Medical College Hospital, Dhaka, Bangladesh during the period of July 2016 to June 2017. A total of 70 cases of BPH planned for TURP were included in this study according to the statistical calculation. Patients were randomly allocated to control group A (TURP without dutasteride) and dutasteride group B (TURP with dutasteride). Each group consisted of 35 patients. Group B patients were treated with dutasteride 0.5 mg/day for 4 weeks before TURP. The main outcome of blood loss was evaluated in terms of reduction in serum hemoglobin (Hb) and hematocrit (Hct) levels, which were measured before and 24 hours after surgery. Data were analyzed and compared by statistical tests. Results: Comparison of outcome between groups shows that there was a significant difference in term of pre-post operative change of hemoglobin and hematocrit levels in the control group A compared to the dutasteride group B (Hb = 2.96 ± 0.80 gm/dl vs. 1.81 ± 0.71 gm/dl, respectively, p = 0.001;Hct = 11.20% ± 2.12% vs. 6.07% ± 2.02%, respectively, p = 0.02). A significant lower mean blood loss was observed in the dutasteride group compared to the control group. Conclusion: Preoperative dutasteride therapy reduces blood loss related to TURP in patients with BPH. This therapy can be practiced to reduce surgical bleeding associated with TURP.展开更多

BPH most commonly causes symptoms associated with LUTS and bladder outlet obstruction. Lower urinary tract symptoms (LUTS) in men with BPH are a major cause of reduced quality of life in older men. If bladder outlet obstruction persists for a longer period of time, the contractility and voiding capacity of the detrusor muscle will gradually be affected by the obstructive factors, eventually leading to a loss of compensatory phase, characterised by a reduced electrical stimulation response, replacement of bladder muscle tissue by connective tissue, and a possible increase in voiding pressure, but a decrease in contractility of the detrusor muscle. As BOO progresses, it eventually leads to permanent contractile dysfunction of the detrusor muscle. Therefore, early initiation of surgical treatment in patients who are not well controlled by medication can reduce the complications associated with prostate enlargement. With the rise of minimally invasive treatment and the complications of open surgery, minimally invasive treatment of BPH has attracted increasing attention. Various emerging minimally invasive surgical modalities are being developed in clinical practice, and more and more minimally invasive techniques and concepts are focusing on safety, improving quality of life and reducing long-term complications to meet the different needs of different patients. Transurethral resection of the prostate (TURP) is currently the “gold standard” of minimally invasive surgical treatment, but with concerns about post-operative complications, the search for safer and more effective minimally invasive surgical options has become even more important. In recent years, with the increasing clinical application of new minimally invasive techniques such as various lasers, interventional treatments and implantable devices, there are more options for minimally invasive treatment of BPH. This article provides a brief review of research advances in the minimally invasive treatment of benign prostatic hyperplasia, with a view to informing clinical decisions.展开更多

It is one of the most common diseases in ageing men. Its clinical presentations are dominated by lower urinary tract symptoms (LUTS). The therapeutic methods can be grouped into two options: the medical option and the surgical option in which prostate enucleation is found. In recent years many studies have reported the onset of urinary incontinence (UI) after prostate enucleation. The management of UI occurring after prostate enucleation is embarrassing for both the practitioner and the patient, and generates additional costs. Purpose: Cite the causes of UI after prostate enucleation for BPH, as well as ways to prevent the onset of UI after this surgery, specifically by the study of the vesicosphincteric system aimed at improving the technique of enucleation;our review will also deal with the therapeutic means of UI. Method: We retrieved studies from Science Direct, Wiley and Pubmed. Results: There are multiple etiologies of UI after prostate enucleation including urethral sphincter insufficiency (USI) and bladder dysfunction (BD). The management of UI after surgery could be conservative, surgical, or use new technologies. Urodynamic assessment before prostate enucleation for BPH is relevant. Conclusion: UI is a common post-operative complication of prostate enucleation. The study of the vesicosphincteric system leads us to believe that prostate enucleation for BPH, partially sparing the mucosa and the external urethral sphincter could decrease the incidence of UI after surgery.展开更多

Methods： Seventy-four consecutive patients who were diagnosed clinically for the prostate diseases, including forty-four cases with benign prostate hyperplasia and thirty cases with prostatic cancer proved pathologically, were examined by PWI. MVD and VEGF were stained with immunohistochemical methods. Some parameters of PWl, including the steepest slope of signal intensity-time curve （SSmax） and the change in relaxation rate （ΔR2^＊ peak） at lesions, were analyzed. Correlation analysis was used to determine the relationship between the results of PWl and immunohistochemistry. Results： （1） In the benign prostate hyperplasia （BPH）, SSmax and ΔR2^＊ peak of perfusion curve were 34.2 ± 2.9 and 1.49 ± 0.11, respectively; however, in the prostatic cancer （Pca）, they were 58.6± 4.8 and 3.18 ±0.49 respectively; there were statistical differences （t = 2.16 and 2.31, P 〈 0.05）. （2） The VEGF and MVD expressions of thirty Pca patients were significantly higher than those of forty-four BPH patients （x2 = 28.64, P 〈 0.01; t = 21.2, P 〈 0.01）. MVD expressions of Pca and BPH groups showed positive associations with VEGF expressions （P 〈 0.01）. On MR perfusion-weighted imaging, SSmax and ΔR2^＊ peak showed associations with MVD and VEGF expressions （P 〈 0.01）. Conclusion： On MR perfusion-weighted imaging, SSmax and ΔR2^＊ peak can reflect MVD and VEGF expression levels in the benign and malignant prostate diseases and might be implied the tumor angiogenesis so as to distinguish benign from malignant and provide the important information for the surgeon to diagnose and treat the prostatic diseases.展开更多

BPH is caused by unregulated proliferation within the prostate, which may cause physical obstruction of the prostatic urethra and result in anatomic bladder outlet obstruction (BOO). Transurethral resection of the prostate (TURP) has been the historical gold standard up till now to which all endoscopic procedures for benign prostatic hyperplasia (BPH) are compared with a mean hospital stay of three days. This surgery although efficacious has been related with increased morbidity and increased day case failure rates as compared to newer techniques. These shortcomings have prompted the utilization of newer methods like Transurethral enucleation and resection of the prostate (TUERP), Holmium laser enucleation of the prostate (HoLEP) and Thulium laser enucleation of the prostate (ThuLEP). This review will discuss the enucleation techniques, advantages and therefore the predictive factors for a successful day case prostate surgery. <strong>Materials and Methods:</strong> During this review, we discuss the newer techniques utilized in day case BPH surgery as well as the predictive factors for a successful BPH surgery, both enucleation, benefits and morcellation are covered also. <strong>Results:</strong> TUERP, ThuLEP and HoLEP have literature supporting the advantages of these techniques, which demonstrates its ability in day case BPH surgeries in specially selected cases with favorable factors and a 61% overall success rate. <strong>Conclusion:</strong> TUERP, ThuLEP and HoLEP Have proven to show favorable outcomes in day case BPH surgery with urologist’s experience, prostate size, duration of operation, age, use of anticoagulants, morning theatre list and ASA score being the key factors for a successful day case surgery.展开更多

Long-term follow-up of the clinical effect of bipolar transurethral resection of the prostate (B-TURP) in saline for BPH is required. Objective: To compare, with long term follow-up, the efficacy and safety of B-TURP in the treatment of BPH with prostate gland volumes of 45 ml, and larger than 60 ml. Materials and Methods: From January 2006 to December 2016, 318 patients with a mean age of 69.45 ± 8.37 years and a median prostate volume of 42 cm3 (56.51 - 32.47) were treated with B-TURP by single urologist (SP) at the Division of Urology, Department of Surgery, Faculty of Medicine, Ramathibodi Hospital, Mahidol University. We retrospectively analyzed the perioperative status of patients’ status follow-up for at least 6 months and up to 5 years. Post-void residual (PVR) and maximum flow rate (Qmax) were assessed preoperatively and postoperatively. Operative time, length of catheterization and hospitalization and complications were all reported. Results: The main indication for B-TURP was failure of medication (81.13%). Perioperative results showed no statistical significance among the groups in terms of catheterization days and the hospitalization length. During the follow-up, the improvement of postoperative parameters was compared with preoperative subscales, at different periods from baseline and after 24, 36, 48, and 60 months post treatment. PSA, Q max, PVR, and average flow rate were significantly different from pre-operation data (p Conclusion: With long-term follow-up, B-TURP is a safe and effective technique for BPH management with prostate gland 45 ml and larger than 60 ml.展开更多

Patients and Methods: 90 patients with PSA levels in the “Gray Zone” PSA (4 - 10 ng/ml) were included. Prostate volumes were estimated using transrectal ultrasonography. Serum PSA levels were measured using an enzyme immunoassay. PSA density was calculated and compared with histopathological results. Statistical analysis was performed using SPSS, t-test, and Contingency Coefficient test. Results: A PSA density cutoff of 0.15 ng/ml/cm3 was used for prostate cancer detection. Mean PSA density for BPH patients: 0.0844 ng/ml/cm3. Mean PSA density for prostate cancer patients: 0.172 ng/ml/cm3. Sensitivity: 92.3%, Specificity: 93.5%, Positive Predictive Value: 70.5%, Accuracy: 93.3%. PSA density significantly reduced unnecessary biopsies (p Conclusions: PSA density can be effective in reducing unnecessary biopsies in patients with intermediate PSA levels, particularly those with organ-confined prostate cancer who are candidates for radical treatment.展开更多

文摘Aim： To explore the feasibility and safety of greenlight photoselective vaporization of the prostate （PVP） on high-risk patients presenting with lower urinary tract symptoms suggestive of benign prostatic hyperplasia （BPH） and to evaluate their clinical and voiding outcome. Methods： A total of 85 high-risk patients with obstructive BPH underwent PVP with an 80 W potassium-titanyl-phosphate laser, which was delivered through a side-deflecting fiber with a 23 Fr continuous flow cystoscope. Operative time, blood loss, indwelling catheterzation, international prostate symptom score （IPSS）, quality of life score （QoL）, uroflowmetry, postvoid residual urine volume and short-term complication rates were evaluated for all patients. Results： All patients got through the perioperative period safely. The chief advantages of PVP were： short operative time （25.6 ± 7.6 min）, little bleeding loss （56.8 ± 14.3 mL） and short indwelling catheterization （1.6 ± 0.8 d）. The IPSS and QoL decreased from （29.6 ± 5.4） and （5.4 ± 0.6） to （9.5 ± 2.6） and （1.3 ± 0.6）, respectively. The vast majority of patients were satisfied with voiding outcome. The mean maximal urinary flow rate increased to 17.8 mL/s and postvoid residual urine volume decreased to 55.6 mL. These results are significantly different from preoperative data （P 〈 0.05）. No patient required blood transfusion or fluid absorption. There were few complications and very high patient satisfaction after operation. Conclusion： PVP has a short operative time and high tolerance, and is safe, effective and minimally invasive for high-risk patients, therefore it might be considered as a good alternative treatment for high-risk patients with obstructive urinary symptoms as a result of BPH.

The main outcome of blood loss was evaluated in terms of reduction in serum hemoglobin (Hb) and hematocrit (Hct) levels, which were measured before and 24 hours after surgery. Data were analyzed and compared by statistical tests. Results: Comparison of outcome between groups shows that there was a significant difference in term of pre-post operative change of hemoglobin and hematocrit levels in the control group A compared to the dutasteride group B (Hb = 2.96 ± 0.80 gm/dl vs. 1.81 ± 0.71 gm/dl, respectively, p = 0.001;Hct = 11.20% ± 2.12% vs. 6.07% ± 2.02%, respectively, p = 0.02). A significant lower mean blood loss was observed in the dutasteride group compared to the control group. Conclusion: Preoperative dutasteride therapy reduces blood loss related to TURP in patients with BPH. This therapy can be practiced to reduce surgical bleeding associated with TURP.
文摘Benign prostatic hyperplasia (BPH) is a chronic condition that is more common in older men. BPH most commonly causes symptoms associated with LUTS and bladder outlet obstruction. Lower urinary tract symptoms (LUTS) in men with BPH are a major cause of reduced quality of life in older men. If bladder outlet obstruction persists for a longer period of time, the contractility and voiding capacity of the detrusor muscle will gradually be affected by the obstructive factors, eventually leading to a loss of compensatory phase, characterised by a reduced electrical stimulation response, replacement of bladder muscle tissue by connective tissue, and a possible increase in voiding pressure, but a decrease in contractility of the detrusor muscle. As BOO progresses, it eventually leads to permanent contractile dysfunction of the detrusor muscle. Therefore, early initiation of surgical treatment in patients who are not well controlled by medication can reduce the complications associated with prostate enlargement. With the rise of minimally invasive treatment and the complications of open surgery, minimally invasive treatment of BPH has attracted increasing attention. Various emerging minimally invasive surgical modalities are being developed in clinical practice, and more and more minimally invasive techniques and concepts are focusing on safety, improving quality of life and reducing long-term complications to meet the different needs of different patients. Transurethral resection of the prostate (TURP) is currently the “gold standard” of minimally invasive surgical treatment, but with concerns about post-operative complications, the search for safer and more effective minimally invasive surgical options has become even more important. In recent years, with the increasing clinical application of new minimally invasive techniques such as various lasers, interventional treatments and implantable devices, there are more options for minimally invasive treatment of BPH. This article provides a brief review of research advances in the minimally invasive treatment of benign prostatic hyperplasia, with a view to informing clinical decisions.
文摘Background: Benign prostatic hyperplasia (BPH) is characterized by the abnormal proliferation of cells, leading to structural changes. It is one of the most common diseases in ageing men. Its clinical presentations are dominated by lower urinary tract symptoms (LUTS). The therapeutic methods can be grouped into two options: the medical option and the surgical option in which prostate enucleation is found. In recent years many studies have reported the onset of urinary incontinence (UI) after prostate enucleation. The management of UI occurring after prostate enucleation is embarrassing for both the practitioner and the patient, and generates additional costs. Purpose: Cite the causes of UI after prostate enucleation for BPH, as well as ways to prevent the onset of UI after this surgery, specifically by the study of the vesicosphincteric system aimed at improving the technique of enucleation;our review will also deal with the therapeutic means of UI. Method: We retrieved studies from Science Direct, Wiley and Pubmed. Results: There are multiple etiologies of UI after prostate enucleation including urethral sphincter insufficiency (USI) and bladder dysfunction (BD). The management of UI after surgery could be conservative, surgical, or use new technologies. Urodynamic assessment before prostate enucleation for BPH is relevant. Conclusion: UI is a common post-operative complication of prostate enucleation. The study of the vesicosphincteric system leads us to believe that prostate enucleation for BPH, partially sparing the mucosa and the external urethral sphincter could decrease the incidence of UI after surgery.
文摘Objective： To explore the application of MR perfusion-weighted imaging （PWI） in the benign and malignant prostate diseases, and evaluate the correlations of PWl features with vascular endothelial growth factor （VEGF） and microvessel density （MVD）. Methods： Seventy-four consecutive patients who were diagnosed clinically for the prostate diseases, including forty-four cases with benign prostate hyperplasia and thirty cases with prostatic cancer proved pathologically, were examined by PWI. MVD and VEGF were stained with immunohistochemical methods. Some parameters of PWl, including the steepest slope of signal intensity-time curve （SSmax） and the change in relaxation rate （ΔR2^＊ peak） at lesions, were analyzed. Correlation analysis was used to determine the relationship between the results of PWl and immunohistochemistry. Results： （1） In the benign prostate hyperplasia （BPH）, SSmax and ΔR2^＊ peak of perfusion curve were 34.2 ± 2.9 and 1.49 ± 0.11, respectively; however, in the prostatic cancer （Pca）, they were 58.6± 4.8 and 3.18 ±0.49 respectively; there were statistical differences （t = 2.16 and 2.31, P 〈 0.05）. （2） The VEGF and MVD expressions of thirty Pca patients were significantly higher than those of forty-four BPH patients （x2 = 28.64, P 〈 0.01; t = 21.2, P 〈 0.01）. MVD expressions of Pca and BPH groups showed positive associations with VEGF expressions （P 〈 0.01）. On MR perfusion-weighted imaging, SSmax and ΔR2^＊ peak showed associations with MVD and VEGF expressions （P 〈 0.01）. Conclusion： On MR perfusion-weighted imaging, SSmax and ΔR2^＊ peak can reflect MVD and VEGF expression levels in the benign and malignant prostate diseases and might be implied the tumor angiogenesis so as to distinguish benign from malignant and provide the important information for the surgeon to diagnose and treat the prostatic diseases.
文摘<strong>Introduction:</strong> Lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) is one among the foremost common diseases affecting the aging man with, almost 80% of the lads greater than 70 affected. BPH is caused by unregulated proliferation within the prostate, which may cause physical obstruction of the prostatic urethra and result in anatomic bladder outlet obstruction (BOO). Transurethral resection of the prostate (TURP) has been the historical gold standard up till now to which all endoscopic procedures for benign prostatic hyperplasia (BPH) are compared with a mean hospital stay of three days. This surgery although efficacious has been related with increased morbidity and increased day case failure rates as compared to newer techniques. These shortcomings have prompted the utilization of newer methods like Transurethral enucleation and resection of the prostate (TUERP), Holmium laser enucleation of the prostate (HoLEP) and Thulium laser enucleation of the prostate (ThuLEP). This review will discuss the enucleation techniques, advantages and therefore the predictive factors for a successful day case prostate surgery. <strong>Materials and Methods:</strong> During this review, we discuss the newer techniques utilized in day case BPH surgery as well as the predictive factors for a successful BPH surgery, both enucleation, benefits and morcellation are covered also. <strong>Results:</strong> TUERP, ThuLEP and HoLEP have literature supporting the advantages of these techniques, which demonstrates its ability in day case BPH surgeries in specially selected cases with favorable factors and a 61% overall success rate. <strong>Conclusion:</strong> TUERP, ThuLEP and HoLEP Have proven to show favorable outcomes in day case BPH surgery with urologist’s experience, prostate size, duration of operation, age, use of anticoagulants, morning theatre list and ASA score being the key factors for a successful day case surgery.

文摘Transurethral resection of the prostate (TURP) is considered as the gold standard for the management of bladder outlet obstruction due to benign prostatic hyperplasia (BPH). Long-term follow-up of the clinical effect of bipolar transurethral resection of the prostate (B-TURP) in saline for BPH is required. Objective: To compare, with long term follow-up, the efficacy and safety of B-TURP in the treatment of BPH with prostate gland volumes of 45 ml, and larger than 60 ml. Materials and Methods: From January 2006 to December 2016, 318 patients with a mean age of 69.45 ± 8.37 years and a median prostate volume of 42 cm3 (56.51 - 32.47) were treated with B-TURP by single urologist (SP) at the Division of Urology, Department of Surgery, Faculty of Medicine, Ramathibodi Hospital, Mahidol University. We retrospectively analyzed the perioperative status of patients’ status follow-up for at least 6 months and up to 5 years. Post-void residual (PVR) and maximum flow rate (Qmax) were assessed preoperatively and postoperatively. Operative time, length of catheterization and hospitalization and complications were all reported. Results: The main indication for B-TURP was failure of medication (81.13%). Perioperative results showed no statistical significance among the groups in terms of catheterization days and the hospitalization length. During the follow-up, the improvement of postoperative parameters was compared with preoperative subscales, at different periods from baseline and after 24, 36, 48, and 60 months post treatment. PSA, Q max, PVR, and average flow rate were significantly different from pre-operation data (p Conclusion: With long-term follow-up, B-TURP is a safe and effective technique for BPH management with prostate gland 45 ml and larger than 60 ml.

文摘To evaluate the effectiveness of PSA density in distinguishing between benign prostatic hyperplasia (BPH) and prostate cancer in patients with intermediate PSA levels (4 - 10 ng/ml) and to reduce unnecessary biopsies. Patients and Methods: 90 patients with PSA levels in the “Gray Zone” PSA (4 - 10 ng/ml) were included. Prostate volumes were estimated using transrectal ultrasonography. Serum PSA levels were measured using an enzyme immunoassay. PSA density was calculated and compared with histopathological results. Statistical analysis was performed using SPSS, t-test, and Contingency Coefficient test. Results: A PSA density cutoff of 0.15 ng/ml/cm3 was used for prostate cancer detection. Mean PSA density for BPH patients: 0.0844 ng/ml/cm3. Mean PSA density for prostate cancer patients: 0.172 ng/ml/cm3. Sensitivity: 92.3%, Specificity: 93.5%, Positive Predictive Value: 70.5%, Accuracy: 93.3%. PSA density significantly reduced unnecessary biopsies (p Conclusions: PSA density can be effective in reducing unnecessary biopsies in patients with intermediate PSA levels, particularly those with organ-confined prostate cancer who are candidates for radical treatment.
文摘Introduction: Open transvesical prostatectomy remains today one of the most effective approaches for the management of benign prostatic hyperplasia despite the fact that, this method is associated with multiple complications. The objective of this study was to evaluate the influence of prostate weight on the morbidity and mortality of transvesical prostatectomy for adenoma in the urology-andrology department of the Ignace Deen National Hospital. Materials and Methods: This was a prospective, longitudinal and analytical study lasting 6 months, from March 1, 2022 to August 31, 2022 including patients admitted and operated on by open transvesical prostatectomy by assessing the influence of prostate weight on the morbidity and mortality of transvesical adenomectomies. Results: 108 patients were included in our study, the average age of our patients was 70 ± 7.7 years, cultivators were the most represented profession with 38.89%, and hypertension was the most represented comorbidity with 75%. 33.06% of cases became complicated and surgical wound infection was the main complication with a frequency of 17.40%. Statistical analysis did not conclude that, the prostate weight does not have a statistically significant influence on the morbidity and mortality of transvesical open prostatectomy for benign prostatic hyperplasia.
