“…Some stated that the bigger the ureteroscope size, the higher the incidence of stricture; others found no correlation. [1819] In our study, in spite of using the 8.5 Fr tipped ureteroscope in the four cases who developed stricture, the caliber of the ureteroscope was not a significant predictor of neither complications, SFR, nor stricture rate.…”

Ureteral stricture after ureteroscopy for stones: A prospective study for the incidence and risk factors

et al. 2019

Context: A ureteral stricture is a serious complication of ureteroscopy (URS) that was reported in the literature in highly variable rates from 0.2% to 24%. Aims: Our aims are to estimate the incidence and to detect the risk factors of ureteral stricture after URS. Settings and Design: This is a prospective, case-series study. Materials and Methods: During the period from May 2015 to August 2016, 251 adult patients underwent 263 URS for the treatment of 304 ureteral stones. Postoperative regular follow-up was done for 12 months by ultrasound. Computed tomography urography and diuretic renogram were performed for the cases developed hydronephrosis to confirm and detect the level of the stricture. Statistical Analysis: IBM SPSS Statistics for Windows, Version 19.0, Armonk, NY: IBM Corp. used for data analysis. Chi-square and Fisher's exact tests were used to compare between qualitative variables. Mann–Whitney test was used to compare between two quantitative variables in case of nonparametric data. Multiple logistic regression analysis was done to measure the risk factors. P value was considered statistically significant when <0.05. Results: The mean age was 43.5 years (standard deviation [SD]: ±13.6), and the mean body mass index was 28.39 (±3.96). The mean total stone burden was 12.8 mm (SD: ±5.9). Bilateral URS was performed in 12 cases. The mean operative time was 54.8 min (SD: ±22.68). Initial and final stone-free rates were 83.3% and 100%, respectively. The overall complications rate was 28.1%. Stricture occurred in four cases (1.5%). Conclusions: In our experience, the incidence of post-URS ureteral stricture is low. The impacted stone is the most common cause of URS complications and hence stricture formation.

“…In addition, the incidences of ureteric stricture were 0.7% and 0.1% in Group 1 and Group 2, respectively ( p = 0.007). Another study summarizing the 15-year experience of a urologist and showed a similar result [7] .…”

“…Compared with a 10 Fr ureteroscope, a 7.5 Fr ureteroscope was associated with a better outcome in the treatment of ureteral stones. A retrospective study of 2461 patients investigated the outcomes of URL with different-caliber semi-rigid ureteroscopes [7] . A 10/10.5 Fr scope was used in Group 1, an 8.9/9.8 Fr scope in Group 2, and a 6/7.5 Fr scope in Group 3.…”

Ureteral stricture formation after ureteroscopic lithotripsy is a late complication that can lead to hydronephrosis and a subsequent risk of renal deterioration. The specific incidence is unknown, and the mechanism of stricture formation has not been completely explained. In this review, we summarize the current evidence regarding the incidence of this condition and discuss its pathogenesis. We then list preventive strategies to reduce the morbidity of ureteral strictures.

“…A higher stone-free rate together with a smaller complication rate could be achieved by using smaller-calibre instruments in adult ureteral stone disease. 12 The majority of ureteric strictures require surgical repair. Distal ureteric strictures are amenable for ureteroneocystostomy.…”

Background: Nephrolithiasis is a common ailment in developing countries such as India. Ureteroscopic management has superseded shockwave lithotripsy as the common treatment for upper urinary tract stones. The process of miniaturizing the instrument along with improved quality of video processor has amplified its potential application, maintaining the procedure safe and effective. However, with its extensive use, complications have risen in parallel, and one should be aware of its adverse effects. Ureteric stricture though rare is a serious problem and risks the loss of renal function. Case presentation: A 37-year-old male presented with right flank pain. On evaluation, he was diagnosed with right upper ureteric stone and left renal stone. The patient suffered ureteric perforation while the right ureterorenoscopy was being performed, and an open repair was done. On postoperative follow-up, he developed long segment ureteric stricture. Boari flap ureteroneocystostomy was done. Conclusion: Iatrogenic ureteric injury following ureterorenoscopy is common, minor and managed conservatively. Important tips to prevent major injury are: placement of the safety guide wire across the length of the ureter, small-calibre scopes during access if a tight gripping sensation is present and the use of lubricant along the length of the ureteroscope.
