Emphysematous pyelonephritis: our experience with conservative management in 14 cases

Emphysematous pyelonephritis [EPN] is a rare, severe, acute, necrotizing infection of the kidney. In this study, we present the clinical details, the management strategies, and the outcome of fourteen patients of EPN managed at our center. A retrospective analysis of the hospital records was done. A total of fourteen patients with EPN were admitted in our hospital from August 2007 to February 2011. All the patients were managed conservatively. Follow-up ranged from six months to one year. Of the fourteen patients, four belonged to class I, five to class II, four to class III A and one to class III B. All the patients had history of fever, 43% had localized flank pain while 36% had vague abdominal discomfort. Renal angle tenderness was the most common sign, seen in 86% of the patients. E. coli was the most common bacteria, which was isolated from urine in 57% of the patients. On the risk factor stratification, three patients had simultaneous presence of 2 or more risk factors [thrombocytopenia-2 patients; renal function impairment-7 patients; shock-1 patient]. All the patients were initially managed with aggressive fluid and electrolyte resuscitation, control of blood sugar levels, and broad spectrum antibiotics. Intervention, in the form of percutaneous drainage or DJ stenting, was done in six patients. One patient failed to respond to this minimally invasive modality of treatment and had to undergo an open drainage. Thus, the acute episode was managed with conservative management strategies in all the patients; however, three patients underwent nephrectomy due to poorly-functioning kidney during follow-up. EPN is now being more readily diagnosed, at an early stage, making conservative management of EPN a safe, effective, and feasible option.

Urinary tract endometriosis: review of 19 cases

The aim of our study was to evaluate the treatment outcomes of medical and surgical management of urinary tract endometriosis. Urinary tract endometriosis patients enrolled between Jan 2006 and May 2010 were retrospectively reviewed. Preoperative datas [mode of presentation, diagnosis, imaging], intraoperative findings [location and size of lesion], postoperative histopathology and follow-up were recorded and results were analyzed and the success rate of different modalities of treatment was calculated. In our study, of nineteen patients, nine had vesical involvement and ten had ureteric involvement. Among the vesical group, the success rate of transurethral resection followed by injection leuproide was 60% [3/5], while among the partial cystectomy group, the success rate was 100%. Among patients with ureteric involvement, success rate of distal ureterectomy and reimplantation was 100%, laparoscopic ureterolysis with Double J stenting followed by injection leuprolide was 75% while that of Gonadotropin- releasing hormone [GnRh] analogue alone was 67%. One should have a high index of suspicion with irritative voiding symptoms with or without hematuria, with negative urine culture, in all premenopausal women to diagnose urinary tract endometriosis. Partial cystectomy is a better alternative to transurethral resection followed by GnRh analogue in vesical endometriosis. Approach to the ureter must be individualised depending upon the severity of disease and dilatation of the upper tract to maximise the preservation of renal function

Rhabdomyolysis and myogloginuric acute renal failure in the lithotomy/exaggerated lithotomy position of urogenital surgeries

To evaluate rhabdomyolysis and it's management in lithotomy and the exaggerated lithotomy positions during urogenital surgeries. Retrospective study. Institute of Post Graduate Medical Education and Research [IPGME and R], Kolkata, India. Patients undergoing urogenital surgeries [lithotomy and the exaggerated lithotomy positions]. All four cases of rhabdomyolysis which occurred after such positional urogenital surgeries were treated with conservative management for prolonged period with hemodialysis. One case which developed compartment syndrome underwent fasciotomy and also managed with conservative approach as other cases. Rhabdomylysis is now a rare complication in any open or laparoscopic surgery. But prolonged lithotomy or exaggerated lithotomy position surgeries have been shown to expose patients to the risk of rhabdomylysis and acute renal failure. In our institute patients undergoing urogenital surgeries in lithotomy and the exaggerated lithotomy positions only developed rhabdomyolysis and myogloginuric acute renal failure. All procedures were of prolonged duration [mean five hours and ten minutes]. Three patients developed rhabdomyolysis and acute renal failure without compartmental syndrome and one with compartmental syndrome. Rhabdomyolysis with the appearance of acute renal failure is discussed. Overall, our cases showed that rhabdomyolysis and acute renal failure can develop in such operative positions even in the absence of compartmental syndrome, and that duration of surgery is the most important risk factor for such complications. So we should be careful regarding duration of surgery in lithotomy procedure to prevent such morbid complications

Minimally-invasive management of prostatic abscess: the role of transrectal ultrasound

Prostatic abscess is an unusual condition. The prevalence of prostatic abscess is about 0.5% of all prostatic diseases. The purpose of the study is to present and discuss the role of transrectal ultrasound [TRUS] in the management of prostatic abscess. Retrospective study. We retrospectively reviewed the medical records of all eight patients diagnosed and treated for prostatic abscess in the last threeyears. TRUS was used for diagnosis in all cases. Four patients had TRUS guided aspiration for management of prostatic abscess. Data collected regarding etiology, clinical features, investigations and treatment was compared with the available literature. The age of patients ranged from 18-65 yrs [mean 47.12 yrs]. Out of the eight patients, six were diabetics. TRUS revealed one or more hypoechoic areas within the prostate in all the patients. Successful treatment of prostatic abscess with TRUS guided needle aspiration was done in all fourpatients in whom it was used. Mean hospitalization time was 9.4 days, and most frequent bacterial agent was S. aureus. TRUS is useful in diagnosis as well as in guidance for aspiration of such abscesses. TRUS guided needle aspiration is an effective method for treating prostatic abscess. Most of the patients are diabetics and usually grow Staphaureus. So an antibiotic with staphylococcal coverage should be used empirically
