The infective complications of PCNL in patients with emphysematous pyelonephritis EPN would be higher and be responsible for the increased morbidity. We retrospectively reviewed our hospital records of patients with EPN and renal stones undergoing PCNL, and assessed the outcome especially in relation to infection. Materials & Methods: The case records of all patients with EPN and renal stones having undergone PCNL at our centre were retrospectively reviewed and analyzed. The age, gender, presenting symptoms, features of septicemia, preoperative drainage, post-operative complications and outcome were recorded. Results: During the study period, 12 patients (eight females and four males) with a mean age of years who were diagnosed to have EPN, underwent PCNL for extraction of renal calculi. All patients were initially managed conservatively;five patients underwent cystoscopy and Double J stent insertion on the affected side and seven patients underwent PCN insertion. Six weeks later, PCNL was performed (Urine culture was negative) undercover of appropriate antibiotics and general anaesthesia. Nine patients had Class II;two patients had class IIIb and one patient had class IV complications as classified by Clavien-Dindo. All patients recovered well and post-operative x-rays showed clearance of stone in all. Conclusions: Percutaneous nephrolithotomy is a safe, viable option in patients with emphysematous pyelonephritis and renal calculi follows a period of conservative treatment and effective drainage of the pelvicalyceal system by either a ureteric stent or percutaneous nephrostomy. The calculi can be effectively managed with endoscopic measures with renal preservation and a good functional outcome.展开更多

It is usually unilateral and occurs as a result of severe renal atrophy or destruction usually due to chronic calculus disease, chronic pyelonephritis and renal tuberculosis. The most commonly used diagnostic investigation remains CECT (contrast enhanced computed tomography) scan. Herein we report our series of patients with total renal replacement lipomatosistreated by nephrectomy. Materials & Methods: We retrospectively reviewed our hospital data for cases of RRL, presented and treated during the period Jan. 2006-Dec. 2015. The age, gender, presenting symptoms, clinical and laboratory findings were noted. The indications for surgery, postoperative outcomes and complications were similarly noted and analyzed. Results: Five patients (three females and two males) with a mean age of 48.4 ± 3.2 years presented with symptoms of pain. Computed tomography (CT) in these patients showed the affected kidney to be completely distorted and replaced by ill-defined fatty attenuating lesion. Open nephrectomy was done in all these patients. Histo-pathological report (HPR) revealed features of RRL with renal calculi. Conclusions: Renal replacement lipomatosis is an uncommon entity, and one should have a high index of suspicion when dealing with suspicious lesions similar to xanthogranulomatous pyelonephritis. Specific imaging, operative, and pathological differences may provide clues for the differential diagnosis.展开更多
