“…However, the ureteral stricture and ureteral size, which are important information to avoid ureteral injury, cannot be precisely detected by fluoroscopy. Early studies showed that a 14/12F UAS could not pass the ureter in 22 % patients and the absence of pre-stenting of the ureter before RIRS was the most significant predictor of the occurrence of severe ureteral injuries [22,23]. Thus, determining the size of ureter and choosing an appropriate size is important to avoid ureteral injuries resulting from the insertion of UAS.…”

The aim of this study was to present the safety and efficacy of retrograde intrarenal surgery (RIRS) procedures that minimize the intraoperative radiation exposure. The totally endoscopy-guided RIRS technique included the following steps: (a) preoperative assessment of pelvicaliceal system anatomy and stone characteristics, (b) thorough evaluation of the ureters by rigid ureteroscopy, (c) a step-wise approach of introducing the ureteral sheath, (d) gathering stones in the more accessible renal calyx before fragmenting them, and (e) a modified holmium laser technique. The RIRS procedures performed by a single surgeon between October 2012 and October 2013 in consecutive patients with renal stones were retrospectively reviewed. The mean stone size was 1.4 ± 0.4 (range 0.8-2.0) cm. The median operative time was 74.5 min. Fluoroscopy was only used in one patient who had a double collecting system with two ureters. The stone-free status was achieved in 134 (95.7%) patients one month after surgery. Five (3.6%) patients had minor complications, including hematuria and fever. No major intraoperative complication was observed. We believe that with appropriate preparation, RIRS without fluoroscopic guidance can be safely and efficiently performed by experienced urologists in selected patients with renal stones.

“…Mogilevkin et al . found that patients with presenting were 21 times more likely to accommodate a 14Fr UAS . In the present study, the double‐J tube was routinely presented in all the patients for 1–2 weeks to dilate the ureter and facilitate the UAS to access the ureter; no patients had ureteral injury when inserting the UAS.…”

Efficacy and functional outcome of flexible ureteroscopy for renal stones in patients with a solitary kidney

et al. 2016

Aim:The aim of the present study was to evaluate the efficacy and functional outcome of flexible ureteroscopy (fURS) for renal stones in patients with a solitary kidney. Patients and Methods: From February 2011 to February 2015, 60 patients with a solitary kidney underwent fURS for the treatment of renal stones. Factors, such as operation duration, complications and stone-free rate (SFR), were analysed. Changes in the renal function were evaluated by comparing preoperative and postoperative glomerular filtration rates (GFR) and serum creatinine. The stage of chronic kidney disease (CKD) was measured to evaluate the influence of fURS on renal function. Results: The total SFR were 76.67 per cent and 93.33 per cent after the first and final procedures, respectively. Postoperative minor complications, classified as Clavien grade II, were recorded in 4.2 per cent (2/48) and 25 per cent (3/12) of patients with renal stones < 2 cm and > 2 cm, respectively. Serious complications, classified as Clavien grade III, occurred in 8.3 per cent (1/12) with renal stones > 2 cm. For patients with renal stones < 2 cm, the preoperative and postoperative mean GFR, as well as serum creatinine, had statistical difference (P < 0.05). For patients with a solitary kidney with stage 5 CKD, fURS did not improve the renal function regardless of the stone size. Conclusion: fURS is a more effective and safer procedure, with a higher SFR and a lower rate of complications in treating stones < 2 cm in a solitary kidney than those > 2 cm. For patients with a solitary kidney with stage 5 CKD, fURS did not improve the renal function regardless of the stone size.
