Aim: To compare the outcomes of supine versus prone mini percutaneous nephrolithotomy for management of renal pelvic stones larger than 2 cm.

Material and Methods: This prospective observational study was conducted at Department of Urology, MMIMSR, Mullana, Ambala from June 2023 to June 2025 among 50 patients with renal pelvic stones more than 2 cm. They were alternatively allocated to group A and B. Group A included patients undergoing supine mini PCNL, while patients undergoing prone mini PCNL were included in group B.

Results: Nephrostomy was kept in 2 (8%) patients in supine mini-PCNL group while 18 (72%) patients among prone mini-PCNL group. There was a significant difference in the number of patients having nephrostomy (p<0.01). Tubeless procedure was done significantly more in supine as compared to prone mini-PCNL group. Mean duration of surgery (in minutes) was significantly more in prone mini-PCNL as compared to supine group as p<0.05. Mean VAS was comparable between supine (5.40) and prone mini-PCNL (5.66) group. Mean hospital stay (in days) was slightly more in prone mini-PCNL (2.49±0.51) as compared to supine group (2.14±0.57) but without significant difference as p>0.05.

Conclusion: Supine and prone mini-PCNL are equally acceptable, equally effective treatment modalities for elderly patients with renal stones. However, prone mini-PCNL had significantly longer fluoroscopy and hospitalisation time. Hence supine mini-PCNL is a potentially safer treatment method.
