This challenging procedure has successful outcomes: Laparoscopic nephrectomy in inflammatory renal diseases

Abstract

In prospective study from November 2011- November 2013, we performed 44 laparoscopic nephrectomies for benign non-functioning kidney diseases. Twenty eight patients underwent laparoscopic transperitoneal nephrectomies (63.6%), ten were laparoscopic assisted (22.7%) and six (13.6%) were converted to open. Patient's age, gender, laterality and etiology of renal failure were noted. Outcomes were measured as operative time, intraoperative and post operative complications, blood loss, pain score and hospital stay. Patients were followed up at one, three and 12 weeks and 6 monthly thereafter. Of the 44, ten (22.7%) were 15-24 years old, 32 (72%) between 25-50 years and two were more than 50 years old. Females were 54.6%. 22 patients had either right or left nephrectomy. Pelviureteric-junction (PUJ) obstruction was the commonest cause, 26 cases (59.0%). Operative time: less than two hours in 30 (68.2%) patients, more than two hours in 14 cases. Blood loss: less than 100 ml in 12 (27.3%), 100-200 ml in 20 (45.4%) and more than 200 ml in 12 (27.3%) patients. All four major complications were converted to open, two had injury to mesocolic veins and two had vascular stapler malfunction. Post-operative complications: surgical site infection (SSI), paralytic ileus and mild grade fever in six cases each and non infected benign intra abdominal collection in two cases. Maximum pain score on POD-1: four in 20 cases (45.7%), two in 24 (54%). Two had pain score between 3-4 three weeks after surgery. Oral intake started by POD-2 in 30 (68.2%) and by POD-4 in 100% cases. 22 (50%) patients were ambulating by POD-2, 16 (36.7%) by POD-4. Our study and randomized and non-randomized published literature report acceptables complication and conversion rates. In conclusion, laparoscopic nephrectomy for benign non functional kidney is a better alternative to open nephrectomy
