Use of Flexible Cystoscope in Removal of Stone in Laparoscopic Pyeloplasty and Pyelolithotomy

Objective: Laparoscopic pyeloplasty and laparoscopic pyelolithotomy are widely used in the treatment of ureteropelvic junction (UPJ) obstructions and renal stones in the urology field. Flexible cystoscopy can be used simultaneously with these methods for removal of calyceal stones in patients with UPJ obstructions. The present study assessed the usefulness of these surgical procedures . Material and Methods: Between February 2016 and October 2017, 7 patients underwent stone removal with a flexible cystoscope during laparoscopic pyelolithotomy and laparoscopic pyeloplasty. The durations of the operations and hospital stays, blood loss, preoperative and post- operative complications, and follow-up times were evaluated. Results: Five of seven patients had renal stones with UPJ obstruction. Two patients had calyceal stones in the lower calyx , in addition to renal pelvic stones. The mean age of the patients was 36.8 (18–73) years. The stone-free rate was 85.7%. The mean duration of the operation was 153.5 (105–230) min, and the duration of the hospital stay was 4.4 (3–7) days. There were no intraoperative or postoperative complications. Conclusion: Laparoscopic pyeloplasty and pyelolithotomy, with simultaneous use of flexible cystoscopy in UPJ obstruction patients with kidney stones and patients with multiple renal stones is a feasible treatment option, with a high success rate
