Efficacy of percoutaneous nephrolithotomy single center one year outcomes

Abstract

Introduction Percutaneous nephrolithotomy (PCNL) is a minimally invasive (keyhole) procedure to remove kidney stones via a small incision in the back. PCNL is typically reserved for the management of large kidney stones. Purpose Analysis of the results obtained in the clinic following PCNL intervention applied to patients with urolithiasis, during one year. Material and methods The cross-sectional study was performed in the Department of Urology and Surgical Nephrology of the State University of Medicine and Pharmacy "Nicolae Testemitanu", within the Republican Clinical Hospital "Timofei Moşneaga", on a batch of 43 patients with Urolithiasis, treated by the PCNL, during the year 2019. Results Anatomical distribution of renal stones: right kidney 21 (48,9%) patients, left kidney 22 (51,1%) patients, dimensions ranged between 2 cm and >4,5cm. Stones dimensions: 2-2,5 cm-18 (41,86%) patients; 2,6- 4 cm-16 (37,2%) patients; >4,5cm – 9 (20,93%) patients. Conclusions Percutaneous nephrolithotomy success rate depended on: stone composition, size, number, location in the urinary tract, BMI, as well as kidney collecting system anatomy. Overall stone free success rate was 90% and 90-100% after a “second look” procedure, with minimal complications.
