Abstract

Background: Treatment of renal stones depends upon the stone size, location, symptoms and any other anatomical variation in the calyceal system of the kidney. Percutaneous nephrolithotomy (PCNL) is a highly effective operation with consistently high stone-free rates; it delivers good stone clearance with minimal problems and a lower retreatment rate, while it is associated with higher morbidity. Retrograde intrarenal surgery (RIRS) is a less invasive and practical therapeutic option with a short hospital stay, minimal morbidity, and a low complication rate. Objectives were to compare the effectiveness of PCNL and RIRS in the treatment of renal stones.

Methods: 50 patients with renal stones with no comorbidities were divided into 2 groups. Group-1 was treated with PCNL, while group-2 underwent RIRS. The outcomes of both procedures were compared based on the operating time, duration of hospital stay and stone-free rate.

Results: The mean duration of hospital stay was higher in the PCNL group (4.37±2.11 days) than the RIRS group (2.84±0.98 days). The stone free rate was more in the PCNL group (96%) as compared to the RIRS group (84%). The PCNL group (78±12.75 minutes) had a longer operative time than the RIRS group (70.59±10.09 minutes. Blood loss was more in the PCNL group.

Conclusions: RIRS is an effective and safe alternative to PCNL in the treatment of renal stones. The choice of surgical approach between PCNL and RIRS should be based on the surgeon's experience and preference and the patient's financial means.
