Castleman's disease is an uncommon disorder characterized by benign proliferation of the lymphoid tissue that occurs most commonly in the mediastinum. Although unusual locations and manifestations have been reported, involvement of the renal parenchyma and sinus, and moreover, manifestations as cardiac tamponade are extremely rare. Here, we present a rare case of Castleman's disease in the renal parenchyma and sinus that also accompanied cardiac tamponade.

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.

We compared postoperative renal function impairment between patients undergoing robot-assisted partial nephrectomy (RAPN) and those undergoing open partial nephrectomy (OPN) by using Tc-99m diethylenetriaminepentaacetic acid (DTPA) renal scintigraphy. Patients who underwent partial nephrectomy by a single surgeon between 2007 and 2013 were eligible and were matched by propensity score, based on age, tumor size, exophytic properties of tumor, and location relative to the polar lines. Of the 403 patients who underwent partial nephrectomy, 114 (28%) underwent RAPN and 289 (72%) underwent OPN. Mean follow-up duration was 35.2 months. Following propensity matching, there were no significant differences between the two groups in tumor exophytic properties (P = 0.818) or nephrometry score (P = 0.527). Renal ischemic time (24.4 minutes vs. 17.8 minutes, P < 0.001) was significantly longer in the RAPN group than in the OPN group, while the other characteristics were similar. Multivariate analysis showed that greater preoperative renal unit function (P = 0.011) and nephrometry score (P = 0.041) were independently correlated with a reduction in glomerular filtration rate. The operative method did not correlate with renal function impairment (P = 0.704). Postoperative renal function impairment was similar between patients who underwent OPN and those who underwent RAPN, despite RAPN having a longer ischemic time.
