Water Vapor Thermal Therapy in Men With Prostate Volume ≥80 cm3: A Systematic Review and Meta-Analysis.

OBJECTIVE: To determine the safety and effectiveness of water vapor thermal therapy (Rezum) in men with large prostate volumes of at least 80cm3. METHODS: We performed systematic searches for studies of Rezum therapy in men with prostate volume of at least 80 cm3. Meta-analysis outcomes included the International Prostate Symptom Score (IPSS), IPSS Quality of Life (IPSS-QOL), Qmax, postvoid residual, International Index of Erectile Function-Erectile Function (IIEF-EF), and serious (Clavien-Dindo grade III-V) complications, surgical retreatments. Outcomes were analyzed using a random effects meta-analysis model. RESULTS: The review included 15 studies (11 retrospective) of 471 men with prostate volume at least 80 cm3 treated with Rezum therapy and followed for a median of 6months (range: 3-17months). Rezum therapy resulted in statistically significant improvements in IPSS (mean change: -11.0; 95% CI: -12.2, -9.7; P < .001), IPSS-QOL (mean change: -2.9; 95% CI: -3.5, -2.4; P < .001), Qmax (mean change: 6.5 mL/s; 95% CI: 4.8, 8.2 mL/s; P < .001), and postvoid residual (mean change: -101 mL; 95% CI: -145, -57; P < .001). No change in IIEF-EF was observed (mean change: 0.3; 95% CI: -1.1, 1.6; P = .71). Serious complications occurred in <0.1% (95% CI: 0.0%, 0.4%) and surgical retreatment in 1.2% (95% CI: 0.0%, 3.5%) of patients. CONCLUSION: Rezum therapy provides a statistically significant and clinically important short-term improvement in lower urinary tract symptoms with low complication rates in men with prostate volume of at least 80 cm3. Long-term outcomes with Rezum therapy in large prostates remain unclear.

The Efficacy of Suspensory Ligament Release and Pubic Lipectomy Via Penopubic Z Plasty During Penile Prosthesis Implantation in Improving Sexual Satisfaction: A Prospective Randomized Controlled Trial.

BACKGROUND: The utility of penile suspensory ligament release (SLR) in the setting of penile prosthesis implantation (PPI) has received limited attention in the literature. AIM: To assess the efficacy and safety of penile SLR release, pubic lipectomy (PL), and the utility of penopubic Z-plasty (ZP) during malleable PPI in improving sexual satisfaction compared to that achieved with the conventional method. METHODS: Between August 2018 and April 2020, 61 patients with refractory erectile dysfunction were prospectively randomized into 2 groups; group A included 31 patients who underwent PPI with SLR and PL via ZP, and group B included 30 patients who underwent conventional PPI via a penoscrotal incision. OUTCOMES: Penile length was assessed at 3 months, and sexual satisfaction was assessed up to 1 year after PPI using both validated and non-validated tools. RESULTS: The median operative time was higher in group A than in group B (170 min; interquartile range [IQR] [160-190] vs 97.5 min; IQR [90-110] P < .001).The median pre- to postoperative differences in functional and visible penile lengths for group A were 1.5 cm; IQR [0-2] and 2.5 cm; IQR [1-3.5], respectively, while those in group B were both 0 cm; IQR [-1 to 0] P < .001). Group A patients reported higher scores in the International Index of Erectile Function satisfaction domains than the group B patients did (13; IQR [12-14] and 9; IQR [8-10] vs 11; IQR [9.5-12] and 8; IQR [6.5-8.5], respectively, P < .001). Moreover, the postoperative Erectile Dysfunction Inventory of Treatment Satisfaction score was higher in group A than that in group B (95.40; IQR [91-97.7] vs 85.20; IQR [72.7-91], respectively, P < .001). Common complications in group A were penile edema (77.4%), penile instability (9.7%) and glans numbness (9.7%). CLINICAL IMPLICATIONS: The benefit in patient satisfaction following SLR and PL via ZP during PPI may outweigh the incremental increase in complications. STRENGTH & LIMITATIONS: To our knowledge, this is the first prospective randomized controlled study to evaluate the efficacy and safety of SLR, PL, and ZP during PPI. However, because an optimal tool for assessing sexual satisfaction after PPI is lacking at this time, we alternatively adopted the most used assessment tools. Further, our data applies only to malleable penile prosthesis. CONCLUSION: SLR and PL via ZP during PPI resulted in a substantial improvement of the patients' sexual satisfaction without serious complications. Fotouh El Gharably MA, Ghoneima W, Lotfi MR, et al.

One-Shot Dilatation vs Metal Dilator During Percutaneous Nephrolithotomy in Flank-Free Supine Position: A Randomized Controlled Study.

Background: The creation and dilatation of the nephrostomy tract is a fundamental step in percutaneous nephrolithotomy (PCNL). In one-shot dilatation (OSD), we used a single Amplatz dilator over a central Alken rod. PCNL in the supine position is as effective and safe as in the prone position. The Barts flank-free modified supine position sums several advantages of the different supine positions. We evaluated the efficacy and safety of OSD compared with metal telescopic dilator (MTD) during PCNL while the patient was in Barts flank-free modified supine position. Materials and Methods: Within 2.5 years, 150 patients with kidney stone candidates for PCNL were randomized into two equal groups according to the dilatation technique. In the OSD group, dilatation was performed using a single Amplatz dilator (30F) and in the MTD group dilatation was performed by sequential MTD (9-30F). All PCNL procedures were done with patients in Barts flank-free modified supine position. Patient characteristics, operative data, and results were collected for statistical analysis. Results: There are no statistically significant differences between both groups regarding patients' characters. The tracts were effectively dilated in all patients. Statistical analyses show a significant difference (p ˂ 0.05) between both groups regarding the time of dilatation (seconds; 68 ± 15 vs 147 ± 18), time of X-ray exposure (seconds; during dilatation; 36 ± 10 vs 61 ± 15 and the total; 157 ± 16 vs 181 ± 20), hemoglobin loss (mg/dL; 0.7 ± 0.2 vs 1.2 ± 0.3), and hospital stay (days; 3 ± 0.6 vs 3.7 ± 0.7) with favorable results to OSD. Complication rates were comparable between the two groups. Conclusions: OSD is efficient as MTD during PCNL while patients are in Barts flank-free modified supine position, with less dilatation time, X-ray exposure, blood loss, and hospital stay than MTD.

Buccal mucosal graft versus penile skin flap urethroplasty for long segment penile urethral stricture: a prospective randomized study.

INTRODUCTION: The aim of this study was to analyze the outcomes of dorsolateral onlay buccal mucosal graft (BMG) and ventral onlay local penile skin flap (LPF) urethroplasty in the management of long segment penile urethral stricture (PUS). MATERIAL AND METHODS: Through a prospective study conducted between October 2014 and May 2018, 84 patients with long segment PUS were randomly assigned to receive either dorsolateral onlay BMG (Group 1 which included 42 patients) or ventral onlay PSF urethroplasty (Group 2 which included 42 patients). The success rate and surgical outcomes were compared in both groups. RESULTS: The success rate was 92.9% in Group 1 and 85.7% in Group 2 (p = 0.5). Postoperative short segment urethral stricture at the site of proximal anastomosis was reported in 3 patients in Group 1. Six patients in Group 2 were considered as a treatment failure, 3 of them due to recurrence of long segment urethral stricture after 6 months, and 3 patients developed ring urethral stricture at the site of proximal anastomosis managed by direct vision internal urethrotomy. CONCLUSIONS: On an intermediate term follow-up, dorsolateral onlay BMG and ventral onlay LPF provide similar success rates in penile urethroplasty, with essentially comparable postoperative morbidity. However, further studies with bigger sample sizes and longer follow-up periods may be required to determine subtle differences between both techniques.

Effect of multiple access tracts during percutaneous nephrolithotomy on renal function: evaluation of risk factors for renal function deterioration.

PURPOSE: To assess the impact of multiple access tracts during percutaneous nephrolithotomy (PCNL) on short- and midterm renal function, and to determine risk factors predicting renal function deterioration and/or recoverability. PATIENTS AND METHODS: Patients undergoing PCNL with multiple punctures were prospectively enrolled. Preoperative evaluation included dimercaptosuccinic acid and diethylenetriaminepentaacetic acid renography. Patients were classified according to baseline renal function into patients with normal (<1.4 mg/dL) serum creatinine (group A) and patients with elevated (≥1.4 mg/dL) serum creatinine (group B). Patients were followed with serial serum creatinine evaluations and a repeated renography at 12 months. Factors evaluated for possible impact on renal function changes included preoperative renal function, number of access tracts, hypertension, and diabetes mellitus. RESULTS: There were 102 patients 21 to 65 (mean 39.9) years who completed the study. Fifty patients (group A) had normal preoperative serum creatinine levels and glomerular filtration rate (GFR), which showed no statistically significant change 12 months after PCNL. Fifty-two patients had baseline renal impairment (group B), and they experienced statistically significant worsening of the serum creatinine level and GFR at 12 months postoperatively (P<0.001). Ten (19.23%) patients in group B had a significant deterioration of GFR more than 25%. Independent risk factors for this poor outcome were elevated (≥1.4 mg/dL) preoperative serum creatinine level, diabetes, and hypertension. CONCLUSION: PCNL with multiple tracts carries a risk of adversely affecting renal function. Preoperative baseline renal impairment, diabetes, and hypertension are risk factors for significant renal function deterioration after the procedure.

Outcomes of hypospadias repair in older children: a prospective study.

PURPOSE: The American Academy of Pediatrics recommendation is to perform hypospadias repair at age 6 to 12 months. However, our patient population included a significant proportion of patients in adolescence and beyond undergoing primary repair. We report a comparison of outcomes in patients in different age groups. MATERIALS AND METHODS: We prospectively report on patients with distal hypospadias who underwent primary repair at our institution during 7 months. Study parameters included age, degree of hypospadias, surgical technique and the complications rate. RESULTS: A total of 61 patients were included in analysis. All cases underwent repair using the tubularized incised plate technique. More proximal hypospadias and different repair techniques were excluded from study. Patients were classified by age, including group 1-25 (40%) 6 months to 2 years old, group 2-17 (28%) 2.2 to 3.7 years old and group 3-19 (32%) 4 years old or older. Only 6 patients (9.8%) had postoperative complications and all were in groups 2 and 3. In group 2 there were 3 complications (17.6%), including loss of repair, meatal stenosis and hematoma in 1 case each. In group 3 there were 3 cases (15.8%) of postoperative fistula. The fistula incidence was higher in group 3 (p = 0.032). CONCLUSIONS: Despite previous reports suggesting a much higher incidence of complications in older children the complication rate is within the acceptable range for infant hypospadias repair in some series. However, these complications were statistically significantly different between the older groups when compared with the recommended age group under American Academy of Pediatrics guidelines.
