| Summary: | Objective: The purpose of the study was to evaluate the effect of internal drainage on the perinephric drain after open renal surgeries. Materials and Methods: 68 patients who had undergone open renal surgeries were prospectively studied. Patients were divided in two groups randomly: Group A (n = 33) without double J stent and group B (n = 35) with Double J stent. In both groups, perinephric drain was placed. Results: The average drain output and duration of perinephric drain kept in group A and B were 36 ml and 29 ml and 4.63 days and 3.35 days, respectively. The commonest surgical complication was wound infection (9.72%). Complaints like frequency, dysuria, and hematuria during follow-up were less in group A than in group B. Conclusion: With the use of double J stent, there is considerable decrease in drain volume and early removal of perinephric drain. Late irritative urinary complaints were seen more in the group with double J stent.
