Comparison of outcomes after minimally invasive versus open partial nephrectomy with respect to trainee involvement utilizing the American College of Surgeons National Surgical Quality Improvement Program.

Purpose: Complication rates of open partial nephrectomies (OPN) and minimally invasive partial nephrectomies (MIPN) have largely been reported by single and multi-institutional tertiary care centers. We sought to identify complication rates of these approaches and how they are influenced by trainee involvement utilizing an independent national surgical database.

Materials And Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) is a risk-adjusted data collection analyzing risk factors, demographics, and 30-day perioperative outcomes.

Incidence and clinical significance of arterial injury in varicocele repair.

Objective: • This study was performed to histologically determine the rate of arterial injury in varicocele ligation surgery and to determine the clinical significance of these arterial injuries.

Materials And Methods: • 41 men who underwent varicocele ligation surgery, and had segments of each ligated vessel examined histologically. • The patients were followed prospectively to determine the effect of arterial injury on surgical results and clinical complications.

Primary adenocarcinoma of the rete testis: improved staging accuracy with CT-PET.

A case of adenocarcinoma of the rete testis in a 54-year-old man is presented. Most such patients harbor metastatic disease, even in clinically localized presentations. CT-PET may provide improved diagnostic sensitivity over conventional CT in this setting.

Collecting duct carcinoma arising from multicystic dysplastic kidney disease.

Malignancy arising from a multicystic dysplastic kidney (MCDK) is rare. Most reports are of Wilms' tumor and clear-cell renal cell carcinoma arising from a previously unrecognized MCDK. To our knowledge, no reports have described collecting duct carcinoma arising from MCDK.

Use of step-section histopathology to evaluate 18F-fluorocholine PET sextant localization of prostate cancer.

To assess positron emission tomography (PET) with fluorine-18 fluorocholine for sextant localization of malignant prostate tumors. Histopathologic analysis was performed on step-sectioned whole-mounted prostate specimens from 15 patients who underwent PET with fluorocholine prior to radical prostatectomy. The maximum standardized uptake value (SUVmax) corresponding to prostate sextants on PET was measured by region of interest analysis and compared with histopathologic results.

Case report: Endoscopic laser lithotripsy of seminal-vesicle stones.

A 25-year-old man presented with painful ejaculation, an ejaculate volume of 0.75, and complaints of passing "granules" in the semen. Transrectal ultrasonography showed bilateral seminal vesicle enlargement.

Perceived stress and quality of life among prostate cancer survivors.

A convenience sample of 136 prostate cancer survivors participated in this study that assessed their perception of stress and quality of life (QOL). Data were collected via an anonymous questionnaire consisting of the Perceived Stress Scale, the UCLA Prostate Cancer Index Short Form, and demographic variables. The findings revealed low levels of stress with marginal reports of QOL.

Dealing with non-cancerous findings on prostate biopsy.

Most prostate biopsies do not show malignancy. The proper management of non-cancerous pathologic findings of the prostate is controversial. For this article, we reviewed the current literature for indications for repeat prostate biopsy after initial biopsies demonstrated non-cancerous prostatic tissue or benign prostatic hyperplasia.

Multiple ipsilateral renal tumors discovered at planned nephron sparing surgery: importance of tumor histology and risk of metachronous recurrence.

Purpose: Unrecognized sporadic multifocality at planned nephron sparing surgery (NSS) presents a surgical dilemma. We report a single institution experience with patients presenting with multiple ipsilateral renal tumors, of which at least 1 was renal cell carcinoma (RCC). We determined the outcome for patients treated with NSS or radical nephrectomy (RN).
