Evaluation of bipolar Transurethral Enucleation and Resection of the Prostate in terms of efficiency and patient satisfaction compared to retropubic open prostatectomy in prostates larger than 80 cc. A prospective randomized study.

OBJECTIVES: To compare the outcomes of bipolar Transurethral Enucleation Resection of the Prostate (TUERP) and simple retropubic prostatectomy in patients with prostate volumes larger than 80 cc. PATIENTS AND METHODS: A prospective randomized study included all patients amenable to surgeries for benign prostate hyperplasia (BPH) with prostate size over 80 cc at a tertiary care hospital between January 2020 to February 2022. Bipolar TUERP and Retropubic open prostatectomy techniques were compared regarding patients' demographics, intraoperative parameters, outcomes, and peri-operative complications. RESULTS: Ninety patients were included in our study and randomly assigned to bipolar TUERP (Group 1 = 45 patients) and retropubic open prostatectomy (Group 2 = 45 patients). The TUERP group demonstrated significantly lower operative time (77 ± 11 minutes vs. 99 ± 14 minutes, p < 0.001), hemoglobin drop (median = 1.1 vs. 2.5, p < 0.001), and resected tissue weight (71 ± 6.6 cc vs. 84.5 ± 10.6 cc, p < 0.001). Postoperatively, the TUERP group demonstrated significantly lower catheter time (median = 2 vs. 7 days, p < 0.001) and less hospital stay. IPSS, Qmax, and patient satisfaction were better in the TUERP group within six months of surgery. We reported 90-day complications after TUERP in 13.3% of patients compared to 17.8% after retropubic prostatectomy, with a statistically insignificant difference. Urethral stricture predominated after TUERP, while blood transfusion dominated in retropubic prostatectomy. CONCLUSIONS: The present study found that TUERP had equivalent efficacy and safety to open retropubic prostatectomy for patients with BPH and prostate volumes > 80 ml.

Comparative study between ureter first approach and conventional open Anderson-Hynes pyeloplasty in paediatric patients: A prospective randomised study.

BACKGROUND: Uretero-pelvic junction obstruction is the most common form of congenital anomaly of the kidney and urinary tract with an incidence of about 1/1.000-1.500 of births and the aetiology and pathogenesis of this anomaly are still unclear until now. METHODS: This is a prospective randomized comparative study conducted from March 2022 to December 2022. Thirty children with uretero-pelvic junction obstruction were included and randomly divided into two groups according to a 1:1 ratio (computer-generated randomization, single blind). Fifteen cases (12 males and 3 female) were subjected to ureter first approach pyeloplasty, and another fifteen (9 males and 6 female) were subjected to conventional Anderson Hynes pyeloplasty. RESULTS: The mean age of all patients was 6.7 ± 5.4 years in ureter first approach group and 5.1 ± 4.3 years in conventional Anderson-Hynes pyeloplasty group. There were no significant differences between the two groups regarding age, gender, presentation, side, preoperative renogram and post-operative renogram. Also, there were no significant differences between the two groups regarding operative time (in first group 110.3 ± 12.4 and in the second group 111.2 ± 12.0 with p < 0.836), pre and post-operative complication rate. Two cases of urinary tract infections in the first group, one of them having fever, and four cases in the second group, two of them having fever (p < 0.651); four cases of loin pain in the first group and one case in the second group (p < 0.330); one case in the first group having pro- longed leakage of urine for 7 days in post-operative period (p < 0.309). However GFR and t 1/2 improved significantly after operation in both groups (p < 0.001). CONCLUSIONS: Ureter first approach is a simple and effective procedure in children with good short term outcomes and could be done safely especially for beginners and less expert surgeons. Finally, it can overcome the problem of long ureteric stricture that may be found intraoperatively because you can shift easily to a flap procedure and complete a tension free anastomosis.

Randomized comparison of effect of standard antibiotic prophylaxis versus enhanced prophylactic measures on rate of urinary tract infection after flexible ureteroscopy.

PURPOSE: To compare the rate of post-flexible ureteroscopy urinary tract infection (UTI) in patients subjected to the standard antibiotic prophylaxis alone versus enhanced prophylactic measures. METHODS: A prospective randomized controlled study included 256 patients subjected to flexible ureteroscopy (FURS) for ureteral or renal stones from March 2018 to July 2022. Treatment groups included the standard antibiotic prophylaxis group (group 1, n=128) and the enhanced prophylaxis group (group 2, n=128). Patients in group 1 were injected with intravenous fluoroquinolone one hour preoperatively, and oral antibiotics were used for 24 h postoperatively. Patients in group 2 had urine culture ten days before the procedure; antibiotic-culture based was given for positive asymptomatic cases, while the procedure was deferred for active UTI. RESULTS: The study groups were comparable regarding patient demographics, stone characteristics, operative time, and intraoperative complications. The overall hospitalization time was 1.68 ± 0.81 days. Postoperative, and overall complications were significantly higher in group 1 (15.6% vs. 6.3%, p = 0.04 and 26.6% vs. 17.2%, p = 0.047), respectively. Twenty patients (15.6 %) in the standard prophylaxis group were diagnosed with UTI in comparison to 8 patients (6.3 %) in the enhanced prophylaxis group (p = 0.047). CONCLUSIONS: Urinary tract infection after FURS could be reduced significantly by utilizing the suggested enhanced prophylactic approach.

Value of preoperative ureteral wall thickness in prediction of impaction of ureteric stones stratified by size in laser ureteroscopic lithotripsy.

OBJECTIVES: To evaluate the role of preoperative UWT in the prediction of impaction of ureteral stones stratified according to stone size in ureteroscopic laser lithotripsy. PATIENT AND METHODS: This study included 154 patients submitted to URSL for ureteral stones. Radiological data comprised the presence of hydronephrosis, anteroposterior pelvic diameter (PAPD), proximal ureteric diameter (PUD), and maximum UWT at the stone site. Collected stone characteristics were stone size, side, number, site, and density. RESULTS: The study included 154 patients subjected to URSL. They comprised 74 patients (48.1%) with impacted stones and 80 (51.9%) with non-impacted stones. Patients were stratified into those with stone size ≤ 10 mm and others with stone size > 10 mm. In the former group, we found that stone impaction was significantly associated with higher PAPD, PUD, and UWT. In patients with stone size > 10 mm, stone impaction was related to higher UWT, more stone number, and higher frequency of stones located in the lower ureter. ROC curve analysis revealed good power of UWT in discrimination of stone impaction in all patients [AUC (95% CI) 0.65 (0.55-0.74)] at a cut-off of 3.8 mm, in patients with stone size ≤ 10 mm [AUC (95% CI) 0.76 (0.61-0.91)] at a cut-off of 4.1 mm and in patients with stone size > 10 mm [AUC (95% CI) 0.72 (0.62-0.83)] at a cut-off of 3.0 mm. CONCLUSIONS: Stratifying ureteric stones according to size would render UWT a more practical and clinically-oriented approach for the preoperative prediction of stone impaction.

Endoscopic combined intrarenal surgery in the prone split-leg position versus Galdakao-modified supine Valdivia position for the management of partial staghorn calculi.

OBJECTIVE: To evaluate and compare the outcome of ECIRS in the treatment of partial staghorn renal calculi in both prone split-leg positions versus GMSV positions with regard to; technical aspects, success rate, operative time, complications, safety, and effectiveness of both approaches. PATIENTS AND METHODS: Between October 2018 and August 2021, 66 patients with partial staghorn calculi were enrolled in this prospective comparative study. Patients were randomly divided according to a 1:1 ratio into two groups. Group A included 33 patients who were treated by (ECIRS) in the prone split-leg position, and group B included 33 patients who were treated by (ECIRS) in the Galdakao-modified supine Valdivia (GMSV) position. RESULTS: No significant statistical difference between both groups regarding the mean age (p = 0.448), mean body mass index (BMI) (p = 0.137), mean stone burden (p = 0.435), mean operative time (p = 0.541) and the number of calyces located in branched stones (p = 0.628). The mean hospital stay was 6.71 ± 1.12 days for group A and 6.66 ± 1.10 days for group B patients (p = 0.724). The final SFR was achieved in (29)87.87% and (30)90.9% of group A & B patients, respectively (p = 0.694). No significant difference was detected between both groups in perioperative complication rates. CONCLUSION: ECIRS is safe and effective in treating partial staghorn calculi either in the prone split-leg position or in the Galdakao-modified supine Valdivia position, with comparable outcomes and no statistically significant difference between both positions.

Short- and long-term follow-up results of daily 5-mg tadalafil as a treatment for erectile dysfunction and premature ejaculation.

OBJECTIVE: To evaluate the safety and effectiveness of daily 5-mg tadalafil treatment for men who have erectile dysfunction (ED) and premature ejaculation (PE), and to assess the long-term follow-up for ED and PE improvement persistence years after the cessation of medication. PATIENTS AND METHODS: A prospective, single-blind, randomised study included 160 patients with ED and PE. All were evaluated using the International Index of Erectile Function (IIEF-5) questionnaire to evaluate ED and intravaginal ejaculatory latency time (IELT) for PE. Patients were subdivided into two equal groups. Group I (80 patients) treated with daily 5-mg tadalafil for 3 months, and Group II (80 patients) treated with a placebo for the same period. After 3 months of treatment and 2 years later after cessation of tadalafil, all patients were assessed for ED and PE. RESULTS: The mean (SD) IELT and IIEF-5 score pre-treatment were 37 (11.24) s and 13.2 (4.2) for Group I, while in Group II they were 35.98 (10.8) s and 13.12 (4.11), respectively. After 3 months of treatment, the mean (SD) IELT in Group I showed a highly significant improvement from 37 (11.24) s to 120.5 (47.37) s (P < 0.001) but Group II showed no significant improvement from baseline to [39.43 (13.6) s; P > 0.05]. For the IIEF-5 score, there was a highly significant improvement from baseline to 20.45 (4.5) in Group I (P < 0.001), while there was no significant difference in Group II from baseline to [15 (4.84); P > 0.05]. At 2 years after cessation of tadalafil, there was statistically significant improvement in the IELT and IIEF-5 from baseline to endpoint . CONCLUSION: Oral daily 5-mg tadalafil was effective, tolerable, and safe treatment for patients with ED and PE. Long-term follow-up at 2 years confirmed the persistence of a significant improvement for both ED and PE.Abbreviations: ED: erectile dysfunction; IIEF-5: five-item version of the International Index of Erectile Function questionnaire; IELT: intravaginal ejaculatory latency time; OAD: once-daily; PDE5i: phosphodiesterase-5 inhibitors; PE: premature ejaculation; PRN: pro re nata.

Temporary vesicostomy in pediatrics: What are the potential predictors of functional and morphological improvement of the upper urinary tract?

INTRODUCTION: Vesicostomy is a simple, well-tolerated, and reversible procedure with few complications that safeguards upper urinary tract (UUT), decreases VUR grade, decreases UTI, and preserves renal function and should be considered in patients with PUV who have undergone prior valve ablation and bladder function not improved, and in myelodysplastic children that do not respond to catheter drainage [1-4]. OBJECTIVE: We evaluated the temporary vesicostomy as a safeguard of the UUT in children with bladder outlet obstruction, bladder dysfunction, and high-grade VUR with sepsis and assessed the possible predictors of the UUT's morphological and functional improvement since these have been rarely explored in previous reviews. STUDY DESIGN: We evaluated the outcome and complications of temporary vesicostomy who were operated on 69 children at our center from 2014 to 2019. RESULT: There were 63 (91.3%) boys and 6 (8.7%) girls who underwent vesicostomy at a mean age of 15.38 ± 2.74 months old. Twenty-nine cases (42%) were diagnosed as primary VUR, 23 (33.3%) had posterior urethral valve (PUV), and 5 (7.2%) had voiding dysfunction, while 12 (17.4%) were neurogenic bladder. Twenty-five (36.2%) patients were diagnosed prenatally and the remainder (44, 63.8%) postnatally. All patients were evaluated at least one year postoperatively. UTI was diagnosed in all cases before vesicostomy; 47 (68.1%) had a single episode of UTI and 22 (31.9%) had recurrent episodes of UTI. Mean serum creatinine was 1.75 ± 0.13 (0.7-4.8) mg/dl. Serum creatinine and the rate of UTI significantly improved (p-value <0.01). Seven (10.1%) cases were complicated with prolapse, 8 (11.6%) with stenosis, and 10 (14.5%) with peristomal dermatitis, all of them were males. DISCUSSION: About 75.4% of cases developed morphological improvement, while 24.6% of cases not improved (p-value = 0.0001). Improvement or stability of glomerular filtration rate (GFR) was seen in 84.1%, while 15.9% deteriorated GFR (p-value = 0.0001). This deterioration is associated with prenatal renal dysplasia. Age less than one year, abdominal swelling, severe HUN, grade V VUR and recurrent UTI before vesicostomy all independently affect functional improvement after vesicostomy. CONCLUSION: Vesicostomy is a simple, reversible, and well-tolerated surgery with few complications that is indicated in children with bladder outlet obstruction, bladder dysfunction, and high-grade VUR to protect UUT, improve renal function, decrease VUR, hydronephrosis, and febrile UTI. Age less than one year, abdominal swelling, severe HUN, grade V VUR and recurrent UTI before vesicostomy all were predictors that independently affect morphological and functional outcomes after vesicostomy.

Endopyelotomy versus redo pyeoloplasty for management of failed pyeloplasty in children: A single center experience.

PURPOSE: We compared endopyelotomy to redo pyeloplasty for the treatment of failed pyeloplasty in children to identify factors that may have an impact on outcome and favor one procedure over the other. METHODS: Of 43 patients with recurrent UPJO, EP was performed in 27 and RP was performed in 16. Age, gender, side, presentation of secondary UPJO, hospital stay, complications and success rates were compared. Success was defined as radiographic relief of obstruction as determined by ultrasound or diuretic renography at latest follow-up. RESULTS: Mean (Range) patient age was 7.2 years (range 6 months to 17 years) in EP (group 1) while 7.4 (range 6 months to 17 years) in RP (group 2). EP technique consisted of retrograde cold-knife in 17 patients, retrograde holmium laser in 8 and antegrade cold-knife in 2. RP was performed in 16 patients. All the patients with failed EP had a stricture greater than 15 mm. Mean length of the narrowed ureteral segment was 17.8 mm in the failed EP group vs 10 mm in the successful group (p < 0.001). Mean Hospital stay was 1 day for the EP group and 5 days for the RP group (p < 0.001). Mean follow-up was 17 months (range 12 to 43) after EP and 21 months (12 to 51) after RP. There was no statistical significance between both groups regarding the postoperative degree of hydronephrosis, parenchymal thickness, split renal functions and renal drainage. The overall success was (86%); the success was nonsignificantly higher in RP (93.8%) vs (81.5%) in EP. CONCLUSION: In selected children, retrograde endopyelotomy is safe and may give comparable short-term outcomes as open redo pyeloplasty for correction of secondary UPJO after failed pyeloplasty. Narrowed ureteral segment greater than 15 mm and preoperative grade 4 hydronephrosis were factors significantly associated with a poor outcome after EP.
