From January 2008 to January 2013, 11 patients with central renal tumors underwent ultrasound-guided open nephron sparing surgery (ONSS) without renal artery occlusion. We removed the lesions, and the cut edges of the tumors were negative. Thus, we deduced that ultrasound-guided ONSS is suitable for the cases with obscure tumor boundary or multiple lesions. It could achieve the purpose of thoroughly removing lesions, as well as to expand the application range of nephron sparing surgery.

PURPOSE: To compare the outcomes of nephron-sparing options (e.g., partial nephrectomy [PN]) and low-surgical-morbidity options (e.g., radical nephrectomy [RN]) in elderly patients with limited life expectancy. MATERIALS AND METHODS: We retrospectively reviewed 135 patients aged 70 years or older who underwent RN (n=82) or PN (n=53) for clinical T1 stage renal masses between January 2000 and December 2012. Clinicopathologic data were thoroughly analyzed and compared between the RN and PN groups. The modification of diet in renal disease equation was used to estimate glomerular filtration. Overall survival and cardiac events were assessed by using Kaplan-Meier survival analysis and Cox proportional-hazards regression modeling. RESULTS: Over a median follow-up period of 59.72 months, 17 patients (20.7%) in the RN group and 3 patients (5.7%) in the PN group died. Chronic kidney disease (<60 mL/min/1.73 m2) developed more frequently in RN patients than in PN patients (75.6% vs. 41.5%, p<0.001). The 5-year overall survival rate did not differ significantly between the RN and PN groups (90.7% vs. 93.8%; p=0.158). According to the multivariate analysis, the Charlson comorbidity index score was an independent predictor of overall survival (hazard ratio [HR], 2.679, p=0.037). Type of nephrectomy was not significantly associated with overall survival (HR, 2.447; p=0.167) or cardiac events (HR, 1.147; p=0.718). CONCLUSIONS: Although chronic kidney disease was lower after PN, overall survival and cardiac events were similar regardless of type of nephrectomy.

INTRODUCTIONWe aimed to evaluate the local incidences of hydronephrosis and renal impairment in the presence of severe uterovaginal or vault prolapse, and determine whether treatment by surgery or ring pessary resulted in the resolution of hydronephrosis in these patients.

METHODSThis was a retrospective case study of 121 patients who presented with severe uterovaginal or vault prolapse. All patients who had fourth degree uterovaginal or vault prolapse, and underwent renal ultrasonography and renal function blood tests were included in the study. Follow-up imaging for hydronephrosis was performed to determine the outcome after patients received treatment.

RESULTSThe mean age of the study population was 66.1 years. The overall incidence of hydronephrosis was 20.6%. The incidence of hydronephrosis in patients with severe vault prolapse was 7.1%, while that in patients with severe uterovaginal prolapse was 22.4%. Of the 25 patients with hydronephrosis, 16 (64.0%) had complete resolution of hydronephrosis after treatment, 5 (20.0%) had residual but smaller degrees of hydronephrosis, and 4 (16.0%) were lost to follow-up. The incidence of renal impairment was 3.3%.

CONCLUSIONThe local incidence of hydronephrosis in patients with severe uterovaginal or vault prolapse was 20.6% in our study. We established that 3.3% of women with severe uterovaginal or vault prolapse had mild renal impairment. Treatment by vaginal surgery for severe uterovaginal or vault prolapse appears to result in either complete resolution or improvement of hydronephrosis in the majority of patients.

Nutcracker syndrome occurs when the left renal vein (LRV) is compressed between the superior mesenteric artery and the aorta, and this syndrome is often characterized by venous hypertension and related pathologies. However, invasive studies such as phlebography and measuring the reno-caval pressure gradient should be performed to identify venous hypertension. Here we present a case of Nutcracker syndrome where the LRV and intra-renal varicosities appeared homogeneously hyperintense on magnetic resonance (MR) fast-spin-echo T2-weighted imaging, which suggested markedly stagnant intravenous blood flow and the presence of venous hypertension. The patient was diagnosed and treated without obtaining the reno-caval pressure gradient. The discomfort of the patient lessened after treatment. Furthermore, on follow-up evaluation, the LRV displayed a signal void, and this was suggestive of a restoration of the normal LRV flow and a decrease in LRV pressure.

The pre-transplantation goal of the urologist is the optimization of urinary tract condition. Therefore, urologic surgery may be needed before or after renal transplantation. We analyzed the results of urologic surgery performed because of de novo urologic diseases. Between January 1986 and January 2001, 281 patients underwent renal transplantation, and 23 urologic surgical procedures were performed on 21 transplant recipients before or after renal transplantation because of de novo urologic diseases. By review the major reasons for urologic surgery in recipients were polycystic kidney diseases, vesicoureteral reflux, and dysfunctional voiding disorders. Nineteen surgical corrective procedures were done average 2.9 months before transplantation. The mortality rate was 10.5%. Four patients underwent urologic surgery at an average 57.5 months after transplantation. We highlight the fact that patients with uremia are vulnerable to surgical complications, and conclude that more intensive longterm urologic follow-ups should be conducted on recipients.

We report a case of surgically treated abdominal aortic aneurysm (AAA) in a patient having crossed ectopia with fusion anomaly of the kidney. One artery from the abdominal aorta above the aneurysm supplies the right kidney while three renal arteries (two from the aneurysm itself and one from the left common iliac artery) supply the crossed ectopic kidney. Preoperative imaging to define the arterial and collecting systems along with a detailed planning of the operation is essential to prevent ischemic renal injury as well as ureteral injury during AAA repair.
