Objective: We aimed to compare the success and complications of ultra-mini percutaneous nephrolithotomy and micro-percutaneous nephrolithotomy techniques.

Methods: We retrospectively analyzed data from 74 patients. Moderate-size stones were included in the study.

Results: Forty-two patients were included in MPNL, and 32 patients were included in UPNL groups. Among our patient cohort, 42 (56.7%)were males, and 32 (43.3%) were females. The mean age of the patients was 40±13.2 years in the MPNL group, and the mean age of the patients was 42±14.1 years in the UPNL group. The mean stone size was 17±3.2 mm in the MPNL group and 16.4±3.7 mm in the UPNL group. The stonefree rates were 88.1% (37/42) and 90.6% (29/32)in the MPNL and UPNL groups, respectively; there was no statically significant difference between the groups. The mean hospital stay was 1.4±0.23 days in the MPNL group and 1.1±0.12 day in the UPNL group.

Conclusions: Two techniques have similar success and complication rates, and both may be preferred particularly in moderate-size stones. Our experience supports that our UPNL technique is safe and effective using with a standard ureteroscope.

Department and Institute of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, No. 1095 Jiefang Avenue, 430030, Wuhan, China.

The aim of this study is to compare the outcomes of flexible ureteroscopy (fURS) and minimally invasive percutaneous nephrolithotomy (mPNL) for the treatment of renal and/or proximal ureteral stones sized 1-2 cm in the elderly (≥60 years). Between January 2010 and March 2015, 184 consecutive mPNL and fURS were performed to treat intermediate renal and/or proximal ureteral stones in geriatric patients. The records were retrospectively reviewed and outcomes were compared. Read More
