Miniperc and retrograde intrarenal surgery were more effective than shock wave lithotripsy to treat 1 to 2 cm radiolucent lower calyceal renal calculi in terms of a better stone-free rate, and lesser auxiliary and re-treatment rates. However, miniperc resulted in more complications, greater operative time and radiation exposure, and a longer hospital stay.

For upper ureteral stones of size greater than 2 cm, LU has a greater stone clearance rate, comparable operating time, lesser need for auxiliary procedure, and complication rate as compared to URS.

Monopolar TURP, Bipolar TURP and PVP provides durable and comparable efficacy at 36 months follow up in patients with prostate size <80 mL.

Objectives: To compare safety and efficacy of ventral versus dorsal onlay buccal mucosal graft urethroplasty in patients with long-segment incomplete bulbar urethral stricture.Methods: This was a single center, prospective, randomized trial. Patients with longsegment (>2 cm) incomplete bulbar urethral stricture and meeting eligibility criteria were enrolled in the study. They were randomized into two study groups: group A undergoing dorsal onlay buccal mucosal graft urethroplasty and group B undergoing ventral onlay buccal mucosal graft urethroplasty. The two groups were compared statistically with regard to International Prostate Symptom Score, maximum flow rate, intraoperative parameters and complications. Results: A total of 80 eligible patients were randomized into two equal groups of 40 patients each. The preoperative International Prostate Symptom Score, maximum flow rate and intraoperative parameters were not significantly different between the two groups. At 12-month follow up, the mean International Prostate Symptom Score showed 324.95% and 353.59% improvement, whereas the mean maximum flow rate showed 208.43% and 201.93% improvement in group A and B, respectively. There was no significant difference between International Prostate Symptom Score and maximum flow rate data between the two groups at 3-and 12-month follow up. The success rate of surgery was similar between group A and B (92.5% vs 90%) with no significant difference noted between them. Conclusion: Dorsal and ventral onlay buccal mucosal graft urethroplasty have comparable efficacy and complication rates for treatment of long-segment incomplete bulbar urethral strictures.
