Randomized Controlled Trial Comparing Open Simple Prostatectomy or Prostate Artery Embolization in Large Prostates: Clinical and Urodynamic Assessment - PoPAE Study.

OBJECTIVE: To evaluate the effects of Prostate artery embolization (PAE) and open simple prostatectomy (OP) on lower urinary tract symptoms and urodynamic parameters in subjects with prostate size >80cc³. METHODS: PoPAE study (OP or PAE) was a randomized, open-label controlled trial performed between January 2020 and May 2022. Subjects with large prostates (>80cc³), urodynamic parameters meeting obstruction criteria (Bladder Outlet Obstruction Index-BOOI>40), and good detrusor function (Bladder contractility index>100) were included. The primary and co-primary endpoints were the variation in peak flow rate on uroflowmetry (Qmax) and BOOI. The secondary endpoints were the IPSS and ultrasonographic changes. RESULTS: Twenty three and 25 subjects underwent PAE and OP were evaluated, respectively. At baseline, the 2 groups have shown similar clinical, radiological, laboratory, and urodynamic parameters. After 6 months, Qmax improved 8,3 ± 4.17 mL/sec in PAE and 15.1 ± 8.04 mL/sec in OP (mean difference 6.78 in favor of PE; P = .012 [CI -9.00 to -3.00]). After treatment, 88% of those men underwent OP were classified as unobstructed or equivocal (BOOi<40). On the other hand, 70% of subjects underwent PAE remained obstructed (BOOI>40) and none of them shifted to unobstructed status (BOOI<20). It was observed a similar reduction in IPSS and PVR in both groups. CONCLUSION: PAE was inferior to conventional surgery for releasing BOO and improving peak urinary flow in large prostates. Nevertheless, PAE was able to improve symptoms and PVR, and might be an alternative method in selected patients.

The role of transurethral resection of prostate (TURP) in patients with underactive bladder: 12 months follow-up in different grades of detrusor contractility.

INTRODUCTION AND OBJECTIVE: Male detrusor underactivity (DUA) definition remains controversial and no effective treatment is consolidated. Transurethral resection of the prostate (TURP) is one of the cornerstones surgical treatments recommended in bladder outlet obstruction (BOO). However, the role of prostatic surgery in male DUA is not clear. The primary endpoint was the clinical and voiding improvement based on IPSS and the maximum flow rate in uroflowmetry (Qmax) within 12 months. MATERIALS AND METHODS: We analyzed an ongoing prospective database that embraces benign prostata hyperplasia (BPH) male patients with lower urinary tract symptoms who have undergone to TURP. All patients were evaluated pre and postoperatively based on IPSS questionnaires, prostate volume measured by ultrasound, postvoid residual urine volume (PVR), Prostate Specific Antigen measurement and urodynamic study (UDS) before the procedure. After surgery, all patients were evaluated at 1-, 3-, 6- and 12-months. Patients were categorized in 3 groups: Group 1-Detrusor Underactive (Bladder Contractility Index (BCI) [BCI] < 100 and BOO index [BOOI] < 40); Group 2-Detrusor Underactive and BOO (BCI < 100 and BOOI ≥ 40); Group 3-BOO (BCI ≥ 100 and BOOI ≥ 0). RESULTS: It was included 158 patients underwent monopolar or bipolar TURP since November 2015 to March 2021. According to UDS, patients were categorized in: group 1 (n = 39 patients); group 2 (n = 41 patients); group 3 (n = 77 patients). Preoperative IPSS was similar between groups (group 1-24.9 ± 6.33; group 2-24.8 ± 7.33; group 3-24.5 ± 6.23). Qmax was statistically lower in the group 2 (group 1-5.43 ± 3.69; group 2-3.91 ± 2.08; group 3-6.3 ± 3.18) as well as greater PVR. The 3 groups presented similar outcomes regard to IPSS score during the follow-up. There was a significant increase in Qmax in the 3 groups. However, group 1 presented the lowest Qmax improvement. CONCLUSION: There were different objective outcomes depending on the degree of DUA at 12 months follow-up. Patients with DUA had similar IPSS improvement. However, DUA patients had worst Qmax improvement than men with normal bladder contraction.

Determining the variables associated to clean intermittent self-catheterization adherence rate: one-year follow-up study

PURPOSE: To determine adherence rate and variables associate with patients' adherence to Clean Intermittent Self Catheterization (CISC). MATERIALS AND METHODS: Patients refereed to CISC training program between July 2006 and May 2008, were prospectively evaluated with urodynamic, 3 days bladder diary (BD) and WHOQoL-bref questionnaire. After training to perform CISC, patients were evaluated at 2 weeks, monthly for 6 months and at 12 months with clinical visits and BD. Patients were considered adherent if they were performing at least 80 percent of the initial recommendation. RESULTS: Sixty patients (50.4 ± 19.9 years old) were trained to perform CISC (21 female and 39 male). Out of them, 30 (50 percent) had neurogenic and 30 (50 percent) had a non-neurogenic voiding dysfunction. The adherence rate at 6 and 12 months was 61.7 percent, 58 percent, respectively. Patients < 40 years old had adherence rate of 86 percent. Women and neurogenic patients had higher adherence rate than their counterparts (p = 0.024 and p = 0.016, respectively). In the WHOQoL-bref, patients that adhere to the program had a significant higher score on psychological and social relationships domains. There was not difference in pre and post training WHOQoL-bref scores. Educational background, marriage status, detrusor leak point pressure, Bladder Capacity, number of leakage episodes did not play a role on the adherence rate. CONCLUSION: Patients in CISC program present a reasonable adherence after one year. Women, neurogenic voiding dysfunction and patients under 40 years old were significantly more adherents. The psychological and social relationship status seems to positively interfere on adherence. CISC did not affect patient's QoL evaluated by WHOQoL-bref.
