ABSTRACT
INTRODUCTION: We intended to evaluate the feasibility and effectiveness of the simultaneous rigid and flexible ureteroscopic treatment of symptomatic ureteral and ipsilateral small simultaneous calyceal stones. Outcomes of combined therapy were compared with monotherapy alone. MATERIAL AND METHODS: In this retrospective study, group 1 consisted of 45 patients with middle or lower ureteral and ipsilateral small simultaneous calyceal stones treated by combined therapy. Group 2 included 45 patients with middle or lower ureteral stones only and treated by monotherapy. Stone characteristics, operative time, hospital stay, stone free rates, and complications were compared between groups 1 and 2. Stone free status was defined as no fragments and/or the presence of asymptomatic fragments smaller than 4 mm. RESULTS: Mean BMI were 29.3 ±0.9 kg/m(2) and 27.6 ±0.6 kg/m(2) in groups 1 and 2, respectively. Mean ureteral stone size (7.6 ±0.4 mm vs. 8.0 ±0.4 mm, p = 0.261) and ureteral stone burden (56.0 ±5.5 mm(2) vs. 54.8 ±6.1 mm(2), p = 0.487) were similar between groups. Mean renal stone size and renal stone burden for group 1 were 7.1 ±0.8 mm and 83.7 ±11.3 mm(2). The mean operative time was significantly longer (for a mean of 32.5±1.2 minutes) for group 1 (p = 0.001). Ureteral stents were left in 38 (84.4%) and 19 (42.2%) patients in group 1 and group 2 (p = 0.001). Hospital stay and complication rates were similar between groups. SFRs were 100% for ureteral stones in both groups and 88.9% for renal stones within group 1. CONCLUSIONS: Simultaneous ureteroscopic treatment of the ureteral and ipsilateral small calyceal stones prolongs operative time and increases use of ureteral stent without leaving any residual renal stones.
ABSTRACT
The case of a simultaneous robotic radical nephroureterectomy, genital tract and paravaginal nerve-sparing robotic radical cystectomy, super-extended pelvic lymph node dissection and intracorporeal Studer pouch construction on a 57-year old female patient with muscle invasive bladder and distal ureteral tumors, along with a hydroureteronephrotic nonfunctioning right kidney is presented. The entire surgery was completed through a total of 8 ports in 9.5 hours. The patient was discharged home on postoperative day-6 and a JJ-stent attached to the urinary catheter was removed altogether on postoperative day-21. This complex surgery can be done safely robotically with excellent oncological outcomes and no surgical and wound complications in the short term.
ABSTRACT
Purpose. To evaluate the safety and efficacy of RIRS for the treatment of multiple unilateral intrarenal stones smaller than 20 mm. Methods. Between March 2007 and April 2013, patients with multiple intrarenal stones smaller than 20 mm were treated with RIRS and evaluated retrospectively. Each patient was evaluated for stone number, stone burden (cumulative stone length), operative time, SFRs, and complications. Results. 173 intrarenal stones in 48 patients were included. Mean age, mean number of stones per patient, mean stone burden, and mean operative time were 40.2 ± 10.9 years (23-63), 3.6 ± 3.0 (2-18), 22.2 ± 8.4 mm (12-45), and 60.3 ± 22.0 minutes (30-130), respectively. The overall SFR was 91.7%. SFRs for patients with a stone burden less and greater than 20 mm were 100% (23/23) and 84% (21/25), respectively (χ (2) = 26.022, P < 0.001). Complications occurred in six (12.5%-6/48) patients, including urinary tract infection or high-grade fever >38.5°C in three cases, prolonged hematuria in two cases, and ureteral perforation in one case, all of whom were treated conservatively. No major complications occurred. Conclusions. RIRS is an effective treatment option in patients with multiple unilateral intrarenal stones especially when the total stone burden is less than 20 mm.
