Abstract
Objectives
The purpose of this study is to compare results, safety and outcome of ultra-mini-percutaneous nephrolithotomy (PCNL) versus stented shock wave lithotripsy (SWL) for the management of renal calculi sized 10-20 mm.
Methods
This study was conducted at Urology Department, Faculty of Medicine, Ain Shams University. After meeting inclusion and exclusion criteria, 90 patients were randomized to either ultra-mini-PCNL group or stented SWL group through the closed-envelope technique, with 45 patients in each group. Patient data were collected preoperatively, immediately postoperatively and 2 and 4 weeks postoperatively assessing operative time, hospital stay, complications including haematuria, fever, the need for blood transfusion, residual stones and the need for retreatment.
Results
Stone-free rate (SFR) was higher in the ultra-mini-PCNL group compared to the stented SWL group, with no statistically significant difference with P-value = 0.316. As for the need for retreatment, it was slightly higher in the stented SWL group compared to the ultra-mini-PCNL group, yet this difference was statistically insignificant with P-value = 0.681.We found no statistically significant difference between both groups regarding post-operative complications including fever, haematuria and need for blood transfusion, respectively.Operative time and hospital stay were significantly higher in the ultra-mini-PCNL group compared to the stented SWL group with P-value < 0.001 for both.
Conclusion
Both stented SWL and ultra-mini-PCNL are good treatment choices for renal stones sized less than 2 cm with low complication rates. Stone size indices were significant predictor for the need for retreatment. Further studies to compare SFR based on stone size in both interventions are needed.
