The Urology Applicant: An Analysis of Contemporary Urology Residency Candidates.

OBJECTIVE: To better understand today's urology applicant. METHODS: All 2016 Urology Residency Match applicants to the study-participating institutions were provided a survey via email inquiring about their paths to urology, their career aspirations, how they evaluate a training program, and how they perceive residency programs evaluate them. RESULTS: Of a possible 468 applicants registered for the match, 346 applicants completed the survey. Only 8.7% had a mandatory urology rotation, yet 58.4% believed that a mandatory urology rotation would influence their career decision. Most applicants (62.1%) spent more than 8 weeks on urology rotations, and 79.2% completed 2 or more away rotations. Applicants were attracted to urology by the diversity of procedures, prior exposure to the field, and the mix of medicine and surgery, with mean importance scores of 4.70, 4.52, and 4.45 of 5, respectively. Female applicants were more likely to be interested in pediatric urology, trauma or reconstructive urology, and female pelvic medicine and reconstructive surgery. Significant differences in survey results were noted when applicants were separated by gender. Three-fourths of respondents (75.7%) applied to more than 50 residency programs. Applicants ranked operative experience, interactions with current residents, and relationships between faculty and residents as the most important criteria when evaluating training programs. Of the subspecialties, 62.1% of applicants expressed most interest in urologic oncology. At this stage in their career, a significant majority (83.5%) expressed interest in becoming academic faculty. CONCLUSION: This study provides new information that facilitates a more comprehensive understanding of today's urology applicants.

The ureteroscope as a safety wire for ureteronephroscopy.

BACKGROUND AND PURPOSE: The recent technologic advances in the newer generation of flexible ureteroscopes have significantly enhanced the therapeutic and diagnostic efficacy of ureteroscopy. The purpose of our study was to assess ureteroscopy and lithotripsy of renal calculi without a safety wire, using the ureteroscope as the safety device. PATIENTS AND METHODS: Medical records for patients undergoing ureteroscopy by a single surgeon were retrospectively reviewed from December 2006 to December 2009. Inclusion criteria for our study included all adult patients who underwent wireless flexible ureteroscopy for the management of renal calculi and had 1 month follow-up data. RESULTS: Of the 568 patients who underwent ureteroscopy during this period, 268 patients met our study inclusion criteria. The mean age of the patients undergoing wireless ureteroscopy was 33 years, and the mean body mass index was 33.1 kg/m(2). Mean stone diameter of the renal calculi treated was 12.0±5.9 mm. Fifteen percent of the patients had a ureteral stent in place before the procedure, and 84% of the patients had a stent placed after ureteroscopy. Twenty percent of the patients needed ureteral dilation, and 15% of the patients had a ureteral access sheath placed intraoperatively. The overall complication rate was 2.6% (major=0.7%, minor=1.9%). Complications included: Four urinary tract infections, two patients with urosepsis, and one patient with urinary retention. No patients had ureteral perforation or ureteral avulsion. CONCLUSIONS: Using the ureteroscope as the safety mechanism, ureteroscopy is safe with regard to maintaining renal access and control. Routine safety wires during ureteronephroscopy are not necessary assuring the ureteroscope is in the kidney.

Role of interleukins, IGF and stem cells in BPH.

The condition known as benign prostatic hyperplasia may be defined as a benign enlargement of the prostate gland resulting from a proliferation of both benign epithelial and stromal elements. It might also be defined clinically as a constellation of lower urinary tract symptoms (LUTSs) in aging men. The purpose of this review is to consider the ways in which inflammatory cytokines belonging to the interleukin family, members of the IFG family, and stem cells may contribute to the development and progression of BPH-LUTS. This might occur in three mechanisms: One, interleukin signaling, IFG signaling and stem cells may contribute to reactivation of developmental growth mechanisms in the adult prostate leading to tissue growth. Two, given that epidemiologic studies indicate an increased incidence of BPH-LUTS in association with obesity and diabetes, IFG signaling may provide the mechanistic basis for the effect of diabetes and obesity on prostate growth. Three, expression of interleukins in association with inflammation in the prostate may induce sensitization of afferent fibers innervating the prostate and result in increased sensitivity to pain and noxious sensations in the prostate and bladder and heightened sensitivity to bladder filling.

Urolithiasis in a rural Wisconsin population from 1992 to 2008: narrowing of the male-to-female ratio.

PURPOSE: Urolithiasis is a common disease with multiple etiologies and risk factors. Studies suggest an increased incidence in developed nations in recent decades as well as differential geographic incidence and prevalence rates, and differences between the genders. We updated urolithiasis epidemiological data by examining the incidence and prevalence rates in a stable rural Wisconsin population. MATERIALS AND METHODS: Data were obtained from the Marshfield Epidemiologic Study Area database, a surveillance tool created in 1991 to track disease in residents of an area of 24 ZIP Codes including approximately 85,000 individuals, of whom most receive care at Marshfield Clinic and affiliates. Urolithiasis cases were identified using ICD-9 codes. Incidence, prevalence and recurrence rates were determined. RESULTS: The mean age adjusted incidence of new onset urolithiasis per 100,000 person-years was 202 (95% CL 168-235) in 1992 and 289 (95% CL 253-325) in 2008. In women the increase per 100,000 person-years was higher than in men, that is 171 (95% CL 129-213) and 289 (95% CL 238-340) vs 238 (95% CL 184-290) and 296 (95% CL 244-348), respectively. The male-to-female incidence ratio decreased from 1.4 to 1.0. The age adjusted prevalence per 100,000 individuals was 1,968 (2%) and 3,554 (3.5%) in 1992 and 2008, respectively. The increase in women was higher than in men (52% vs 26%). The age adjusted recurrence rate per 100,000 individuals was 553 (0.72%) and 676 (1.0%) in 1992 and 2008, respectively. The increase in women was higher than in men (88% vs 20%). CONCLUSIONS: Since 1992, urolithiasis incidence, prevalence and recurrence rates in this rural Wisconsin population have increased with higher increases noted in women. While prevalence increased, it was lower than reported in other geographic areas in the United States.
