RESUMEN
OBJECTIVE: To evaluate the effect of semirigid ureteroscopy and tamsulosin therapy as dilatation methods before flexible ureteroscopy advancement to the renal collecting system. PATIENTS AND METHODS: This prospective study included patients with renal stones less than 2 cm who underwent retrograde flexible ureteroscopy and laser lithotripsy. The patients were randomized into two groups: group A patients were given a placebo for 1 week before flexible ureteroscopy, and group B patients were administered 0.4 mg of tamsulosin once daily for 1 week before surgery and underwent active dilatation using semirigid ureteroscopy before flexible ureteroscopy. The ability of the flexible ureteroscope to reach the collecting system in both groups during the same operative session was assessed. Operative outcomes and complications were collected and analyzed in both groups. RESULTS: A total of 170 patients were included in our study, with each group comprising 85 patients. In group B, the flexible ureteroscope successfully accessed the kidney in 61 patients, while in group A, the flexible ureteroscope was successful only in 28 cases (71.4% versus 32.9%). In group A, 33 (38.8%) patients had lower urinary tract symptoms compared to 17 (20.2%) patients in group B (P = 0.013). CONCLUSION: Using tamsulosin therapy and semirigid ureteroscopy as dilatation methods before flexible ureteroscopy increased the success of primary flexible ureteroscopy advancement to renal collecting system.

PURPOSE: We conducted this study, comparing the outcomes among Transverse Onlay Island Flap, inlay grafted incised plate and our previous records of tubularized incised plate urethroplasty (TIPU) in patients with narrow urethral plates, aiming to determine which method of repair provides a good outcome. METHODS: This hybrid study included two datasets. The first from a prospective randomized study evaluating outcomes of two treatment modalities; Inlay graft and only flap for distal hypospadias with shallow urethral plate with 80 patients (40 patients in each group) included, the second based on our previous records of TIPU in 40 patients with distal primary hypospadias with narrow urethral plate. RESULTS: The success rate in inlay graft urethroplasty group (n = 40) was 87.5%; glandular dehiscence occurred in one case (2.5%), fistulas occurred in 2 cases (5%), and narrow meatus occurred in two cases (5%). Success rate in onlay flap urethroplasty group (n = 40) was 82.5%; glandular dehiscence occurred in two cases (5%), fistulas occurred in two cases (5%), and narrow meatus occurred in three cases (7.5%). TIPU group (n = 40) had success rate of 62.5%; glandular dehiscence occurred in eight cases (20%), fistulas occurred in five cases (12.5%), and narrow meatus occurred in seven cases (17.5%), with five cases exhibiting both narrow meatus with fistula. CONCLUSION: Inlay graft and onlay flap urethroplasty for repair of distal penile hypospadias with narrow urethral plate had higher success rate and fewer complications than traditional TIPU. Moreover, operative time was shorter in TIPU.

OBJECTIVES: To compare the clinical performance and surgical outcomes of the new digital single use flexible ureteroscope (WiScope®) with a reusable digital flexible ureteroscope. PATIENT AND METHODS: Our prospective study includes patients with renal stones less than 2 cm who underwent retrograde flexible ureteroscopy and laser lithotripsy. Patients were randomized into two groups: group A included patients who underwent laser lithotripsy using WiScope® Single use digital flexible ureteroscope and group B included patients who underwent laser lithotripsy using reusable flexible ureteroscope. Image quality, deflection, ease of insertion, maneuverability, and overall performance were assessed using either a visual analog or Likert scale. Operative outcomes and complications were collected and analyzed in both groups. RESULTS: A total of 242 patients were included in our study. There were 121 patients in the WiScope® group and 121 patients in reusable ureteroscope group. The WiScope® had higher maneuverability (9.3 ± 0.7 vs. 7.2 ± 0.8, P < 0.001) and less limb fatigue but had lower image quality when compared to reusable digital flexible ureteroscope (7.6 ± 0.9 vs. 9.2 ± 0.6, P < 0.001). There were no differences in operative time, complication rates and rates of relook ureteroscopy. CONCLUSIONS: The WiScope® single use flexible ureteroscope has comparable outcomes to the reusable flexible ureteroscope with regard to maneuverability, limb fatigue, and deflection. However, it has a lower image quality.

PURPOSE: We report our experience with transperitoneal laparoscopic nephrectomy (LN) for giant hydronephrosis (GH) and compare the outcome data with open nephrectomy (ON). PATIENTS AND METHODS: The retrospective data of 88 patients (52 males and 36 females) who underwent LN or ON for treatment of GH in the period between October 2015 and December 2019 were investigated. LN was performed in 38 patients, while 50 patients underwent ON. We compared the two groups for success, operative time, and intraoperative and postoperative complications. RESULTS: The mean age of the patients in the LN group was 45.8 ± 11.4 years, and it was 44.7 ± 10.8 years in the ON group. The mean operative time in the LN group was statistically significantly longer when compared with the ON group195 ± 18 min versus 127 ± 22 min (p = 0.01).The estimated blood loss was significantly greater in the ON group (p = 0.01). However, no patients required blood transfusions in either group. The visual analog pain (VAP) scores were significantly higher on both day 1 and day 2 in the ON group 3.6 ± 0.9 and 2 ± 0.7 versus 2.7 ± 0.6 and 1.4 ± 0.5 in LN group, (p = 0.01). CONCLUSION: LN for GH is feasible, safe, and efficacious. Compared to open surgery, the laparoscopic approach resulted in significantly shorter hospital stays, decreased morbidity, and quicker recovery. Some tips and tricks could help to do it in an easier way and reduce the operative time.
