ASSESSMENT OF EFFICACY, SAFETY AND POSTOPERATIVE OUTCOME OF STANDARD PERCUTANEOUS NEPHROLITHOTOMY VERSUS TUBELESS PERCUTANEOUS NEPHROLITHOTOMY IN CASES OF NEPHROLITHIASIS:A RANDOMIZED CONTROLLED TRIAL

Present study is a single institute, prospective study, with intention to compare and evaluate the effectiveness and safety of standard percutaneous nephrolithomy (PCNL) versus tubeless PCNL in the Department of Urology, Sri Sathya Sai Institute of Higher Medical Sciences – Prasanthigram, Anantapur, Andhra Pradesh. A minimum of 100 cases of renal stone disease that are willing to undergo PCNL will be included after taking written informed consent. Patients will be divided randomly into two groups involving minimum of 50 patients in each group. Group A patients will undergo Tubeless PCNL procedure and Group B patients will undergo Standard PCNL. The routine evaluation of patients enrolled in the study will be done as per the structured proforma. The efficacy and safety of the operative procedure will be analyzed based on postoperative pain score, analgesia requirement, fall in haemoglobin, blood transfusion requirement, duration of hematuria, duration of urine leak, duration of hospital stay and any other postoperative complications.The purpose of this study is to objectively compare the standard and tubeless PCNL depending on different variables and at the end of the study to provide guidance regarding preference of choice among the two methods in cases of nephrolithiasis.
