A Modified Technique for Performing Transurethral Resection of the Prostate Combined with Percutaneous Cystolithotripsy

Abstract

Introduction: This study aimed to determine the safety and efficacy of a modified technique for performing transurethral resection of the prostate (TURP) combined with percutaneous cystolithotripsy (PCCL). Methods: Clinical data from 24 patients with benign prostate hyperplasia (BPH) and aggregate stone sizes ≥3 cm were assessed retrospectively between June 2011 and January 2014. All stones fragmented via pneumatic lithotripter were removed. An 18-F Foley catheter was inserted into the Amplatz sheath, which was then removed from the bladder. The Foley catheter balloon was inflated with 15 ml of saline, and suprapubic traction was applied to prevent extravasation. Next, TURP was performed while a suprapubic Foley catheter provided continuous drainage. Results: The mean stone size was 46.25 ± 9.51 mm. The surgical duration for stone removal was 31.25 ± 8.46 min. All patients were stone-free at the first month follow-up. None of the patients experienced extravasation or urethral stricture. Conclusions: PCCL is a short-duration, minimally invasive surgery that avoids urethral stricture. In the presented technique, as the drainage catheter is fixed to the dome of bladder, it is not visualized in the surgical field and remains outside of the resection area, which facilitates prostate resection. It seems to be a safe and efficient technique.
