Neuraxial vs General Anesthesia: 30-Day Mortality Outcomes Following Transurethral Resection of Prostate.

OBJECTIVE: To examine the occurrence of 30-day mortality, and other procedure related morbidities in cohorts of patient receiving neuraxial anesthesia (NAX) or general anesthesia (GA) in the setting of transurethral resection of the prostate (TURP). Historically, NAX has been recommended for patients undergoing TURP permitting monitoring of consciousness and early diagnosis of absorption-related hyponatremia. We aim to analyze a broader comparison of mortality and other associated morbidities regarding the form of anesthesia utilized. METHODS: The National Surgical Quality Improvement Program (NSQIP) database was accessed and queried from January 2010 to December 2016 for TURP. 28,486 TURP cases were identified and further stratified by the type anesthesia administration, NAX 7,261 and GA 21,225. Chi-square analyses and Kaplan-Meier tests were performed for univariate comparisons. Using propensity score, data were optimally (1:1) matched to account for potential confounding variables. Outcomes were then compared for NAX vs. GA with a primary endpoint of 30-day mortality, followed by secondary endpoint of adverse outcomes reported per NSQIP. RESULTS: Prior to matching, 30-day mortality was found to be 0.4% in the NAX cohort and 0.7% GA. 12,180 patients equally matched between the 2 groups. NAX was found to be superior to GA in terms of 30-day survival benefit (OR 0.55, 95% CI 0.33 -0.92, P <0.05), sepsis (OR 0.60, 95% CI 0.50 -0.73, P <0.001), and return to operating room (OR 0.76, 95% CI 0.60 -0.98, P <0.05) when comparing matched cohorts. NAX was associated with lower incidence of overall adverse clinical outcomes 12.4% vs 13.7% (P = 0.036). CONCLUSION: NAX was found to have statistically relevant advantage for 30-day postoperative outcomes when compared to GA for TURP based on NSQIP database reporting.

Renal Oncocytoma and Retroperitoneal Ancient Schwannoma: A Benign Mimic of Metastatic Renal Cell Carcinoma.

Renal oncocytomas and retroperitoneal schwannomas are rare and typically benign tumors with characteristic histopathologic features. Ideal management of both renal oncocytoma and retroperitoneal schwannoma is surgical resection. We present a rare case of a 63-year-old man with multifocal renal oncocytoma and retroperitoneal ancient schwannoma which, preoperatively, masqueraded as metastatic renal cell carcinoma. Both tumors were successfully resected surgically. Immunochemistry and histopathology confirmed each diagnosis.

Pathological correlation between needle biopsy and radical prostatectomy specimen in patients with localized prostate cancer.

OBJECTIVE: This study aims to evaluate the accuracy of transrectal ultrasound (TRUS) guided prostate biopsies in predicting pathological grading and tumour distribution in the final pathological specimen of patients who underwent radical prostatectomy for clinically localized prostate cancer. The study ultimately aims to gain more understanding of the pathological behaviour of prostate cancer and the limitations of the currently available diagnostic and prognostic tools. MATERIAL AND METHODS: We reviewed the records of 100 patients with localized carcinoma of the prostate diagnosed by TRUS-guided prostate biopsy and treated with radical retropubic prostatectomy, comparing tumour laterality and Gleason score in core biopsies with tumour distribution and Gleason score of the surgical specimen. We then correlated both results to diagnostic and prognostic variables such as prostate specific antigen (PSA) values and surgical margins. RESULTS: All 44 patients with bilateral disease on needle biopsy had bilateral disease on final pathology, with 15 of these patients (34%) having positive margins. Of the 56 patients with unilateral disease on biopsy, 37 (66%) had bilateral disease on final pathology; however, only 4 of them (7%) had positive margins (p < 0.001). Median Gleason score on final pathology was upgraded to 7, compared with a median score of 6 on biopsies. Stratifying patients to 2 groups based on their PSA level (group 1: PSA < 10 ng/mL, 72 patients; group 2: PSA > 10ng/mL, 28 patients), revealed that 57 patients (79%) in group 1 and 24 patients (85%) in group 2 had bilateral disease. In addition, 13 patients (18%) in group 1 and 6 patients (21%) in group 2 had positive margins. CONCLUSIONS: Sixty-six percent of patients with unilateral disease on needle biopsy had bilateral disease on final pathology, but this does not increase their rate of having positive margins. Gleason score is upgraded from 6 to 7. PSA did not seem to affect laterality of disease in patients selected for radical prostatectomy.

The workup of microscopic and gross hematuria.

Based on the American Urological Association best practice policy statement, the workup of microscopic hematuria is summarized in the above algorithm (Fig. 1). The presence of gross hematuria is always an indication for prompt full investigation.
