COMPARATIVE STUDY BETWEEN STANDARD AND TUBELESS PERCUTANEOUS NEPHROLITHOTOMY PROCEDURES FOR SURGICAL MANAGEMENT OF KIDNEY STONES.
Introduction: Percutaneous Nephrolithotomy (PCNL) is an effective treatment for renal stone. Due to significant pain and morbidity after standard PCNL because of nephrostomy tubes, various modifications of PCNL are being performed. We report a randomised trial comparing these modalities. Material and method: 50 patients were randomised in two groups of 25 each: standard PCNL with nephrostomy tubes (Group 1) and tubeless PCNL with ureteric stent and no nephrostomy (Group 2). At the end of procedure randomisation was done for those patients satisfying the inclusion criteria based on duration of surgery, single puncture tract, intraoperative bleeding, stone burden, intact pelvicalyceal system and no residual stone at end of procedure. Hb drop, haemorrhage, need for blood transfusion, pyrexia, urine leak, pain score, analgesic requirement and duration of hospital stay were measured. Results: No significant difference in haemorrhage was observed. Urinary leak was only seen in one patient of standard group. Duration of hospital stay and analgesic requirement attained statistical significance in favour of tubeless group compared to standard. Conclusion: Tubeless is effective and safe method for management of renal stones. It reduces postoperative pain and morbidity compared to standard group.
