This sheath is the same diameter in its entire length. Our aim is to reduce the ureteral damage due to the surgical treatment of pelvic ureteral calculi, especially in women and children. The objective of this study is to compare the results of m-URS and conventional ureteroscopy in terms of efficacy and safety. A comparative prospective-retrospective study was designed. METHODS The study was approved by the ethics and research committee. We prospectively analyzed the patients operated by m-URS (Group A) and compared them with a randomly selected sample of patients treated with conventional ureteroscopy (group B), using a semi-rigid ureteroscope (7.5 - 9.5 Fr). Inclusion criteria were: patient agreement to participate in the study, pelvic ureteral stone, and no response to medical expulsive therapy for 30 days or bad pain control (measured with Visual Analogue Scale) despite adequate analgesic treatment for more 48 hours. Exclusion criteria were not accepting participation in the study or the presence of urinary clinical or analitical sepsis criteria. Data regarding age, size of the stone, hospital stay, surgical time, need for postoperative ureteral stenting, duration of postoperative stenting or need for readmission among others were collected. SPSS.13 was used as statistical software. RESULTS We treated 34 women, 13 by m-URS and 21 by conventional URS. The average age was 54.38 years in group A and 54.66 years in group B. The mean size of the stones was 41.08 mm2 in group A and 33.02 mm2 in Group B. The operative time was 54.15 min. (Group A) vs 42.24 min (group B). The stone free status was achieved in 100% in group A and 95% in group B. A stent was placed in 100% of patients undergoing conventional URS and in 38% of operated by m-URS (p = 0.000). The hospital stay was 0.85 and 1.29 days, respectively. When the stent was placed, the duration of the catheterization was 4.46 days in group A and 19 days in group B (p <0.005). No major complications were reported. The only readmission in the m-URS group was due to neurological symptoms in a patient with Guillain-Barré syndrome. CONCLUSIONS Micro-ureteroscopy is an effective and safe technique for treating pelvic ureteral stones in women and significantly reduces the need for postoperative stenting and duration of ureteral catheterization. © 2016FiguresReferencesRelatedDetails Volume 195Issue 4SApril 2016Page: e255 Advertisement Copyright & Permissions© 2016MetricsAuthor Information Juan-Pablo Caballero-Romeu More articles by this author Juan-Antonio Galán-Llopis More articles by this author Helena Pérez-Seoane More articles by this author Alejandro-Jose Garcia-Segui More articles by this author Aleixandre Verges-Prosper More articles by this author Araceli Amorós-Torres More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
