A simple method to estimate renal volume from computed tomography.

Introduction: Renal parenchymal volume can be used clinically to estimate differential renal function. Unfortunately, conventional methods to determine renal volume from computed tomography (CT) are time-consuming or difficult due to software limitations. We evaluated the accuracy of simple renal measurements to estimate renal volume as compared with estimates made using specialized CT volumetric software.

MRI and its role in the evaluation and surgical decision making in patients with challenging IPP presentations: descriptions of MRI findings and algorithm for patient management.

Unlabelled: Study Type - Diagnostic (case series) Level of Evidence 4 What's known on the subject? and What does the study add? It is known that magnetic resonance imaging (MRI) is safe and effective for imaging patients with inflatable penile prostheses (IPPs). Previous series have reported results of MRI for imaging series of patients with IPPs. The impact on management in particular with regard to salvage procedures is not well defined.

Renal nephrometry score is associated with urine leak after partial nephrectomy.

Objective: • To determine if the RENAL nephrometry score is associated with urine leak after partial nephrectomy for tumours ≤ 7 cm.

Patients And Methods: • Thirty-one patients who developed urine leak after partial nephrectomy between 1998 and 2006 were identified. Each patient was individually matched (1 : 4 by age, gender and surgery date) to 124 patients who had undergone partial nephrectomy but without urine leak.

Lower urinary tract leiomyoma: is excision necessary?

Introduction/objectives: Our objective was to review our experience with lower urinary tract leiomyomata to determine if presentation, exam and imaging allows for stratification of the treatment of this rare lesion.

Materials And Methods: A retrospective review of current practice was performed from the Mayo Clinic Rochester database identifying 13 female patients and 10 males from 1995-2008, focusing on the clinical presentation, cystoscopic findings, imaging and operative approaches.

Results: Symptomatic patients had larger lesions, were more likely to be females, or had midline periurethral or bladder neck lesions.

Case report: percutaneous catheter management of persistent urine leak due to iatrogenic infundibular stenosis after partial nephrectomy.

We describe two cases of persistent urine leak after partial nephrectomies that were both due to surgically induced isolated calices. We hypothesize that the isolated calices were created while suturing the collecting systems, with inadvertent closure of single infundibula. Both cases were managed by percutaneous nephrostomy tube drainage of the renal pelvises and the isolated calices, in addition to indwelling ureteral stents.

Retroperitoneal mucinous cystadenocarcinoma in a man: case report and review of the literature.

In the English medical literature, 27 cases of primary retroperitoneal mucinous cystadenocarcinoma have been published. We report the second case of a primary retroperitoneal mucinous cystadenocarcinoma in a man. The patient was an 83-year-old man, with a large 26 x 20 x 16-cm retroperitoneal cystic mass causing abdominal discomfort and cachexia, who underwent excision of the mass.
