Objective: To compare outcomes of Extracorporeal shock wave lithotripsy (ESWL) versus Percutaneous nephrolithotomy (PCNL) in partial staghorn stone.
Methodology: This study was done from May 25, 2013 to November 25, 2013 at Sindh Institute of Urology and Transplantation (SIUT), Karachi, Pakistan. It included 60 patients with normal contralateral kidney on ultrasound, normal renal function with a creatinine of under 1.2mg/dl, stone size more than 2.0cm, duration of stones more than 3 months, age ranged from 30-70 years of either gender. Randomization was made and divided into Group A and B will undergo PCNL and ESWL, respectively.
In group A, PCNL was done and in group B, ESWL was done, Maximum 3 session with interval of 14 days in each session but prior ESWL Double J stent was passed. Final outcome was measured at the end of 1 week in PCNL group and every 2 weekly for 12 weeks in ESWL group. Ultrasound was done and the absence of residual stones in the kidney was categorized as positive outcome.
Results: Out of 60 patients, 63.30% were males and 36.70% females. Mean age of patients was 4.83±7.28years. Mean stone size was 48.26 ±15.67mm and mean stone duration was 4.93±1 month. In PCNL group, satisfactory outcome was noted in 29 (96.7%) patients whereas in ESWL group, it was noted in 4 (13.3%) patients (p=0.001).
Conclusion: Outcome of PCNL was better than ESWL in patients with partial staghorn stone.
Key words: Percutaneous nephrolithotomy (PCNL), extracorporeal shock wave lithotripsy (ESWL), partial staghorn stone.
