Prior Negative Biopsy, PSA Density, and Anatomic Location Impact Cancer Detection Rate of MRI-Targeted PI-RADS Index Lesions.

BACKGROUND: MRI fusion prostate biopsy has improved the detection of clinically significant prostate cancer (CSC). Continued refinements in predicting the pre-biopsy probability of CSC are essential for optimal patient counseling. We investigated potential factors related to improved cancer detection rates (CDR) of CSC in patients with PI-RADS ≥ 3 lesions. METHODS: The pathology of 980 index lesions in 980 patients sampled by transrectal mpMRI-targeted prostate biopsy across four medical centers between 2017-2020 was reviewed. PI-RADS lesion distribution included 291 PI-RADS-5, 374 PI-RADS-4, and 315 PI-RADS-3. We compared CDR of index PI-RADS ≥ 3 lesions based on location (TZ) vs. (PZ), PSA density (PSAD), and history of prior negative conventional transrectal ultrasound-guided biopsy (TRUS). RESULTS: Mean age, PSA, prostate volume, and level of prior negative TRUS biopsy were 66 years (43-90), 7.82 ng/dL (5.6-11.2), 54 cm3 (12-173), and 456/980 (46.5%), respectively. Higher PSAD, no prior history of negative TRUS biopsy, and PZ lesions were associated with higher CDR. Stratified CDR highlighted significant variance across subgroups. CDR for a PI-RADS-5 score, PZ lesion with PSAD ≥ 0.15, and prior negative biopsy was 77%. Conversely, the CDR rate for a PI-RADS-4 score, TZ lesion with PSAD < 0.15, and prior negative biopsy was significantly lower at 14%. CONCLUSIONS: For index PI-RADS ≥ 3 lesions, CDR varied significantly based on location, prior history of negative TRUS biopsy, and PSAD. Such considerations are critical when counseling on the merits and potential yield of prostate needle biopsy.

Patient Understanding and Perception of Urology Resident Training, Role, and Capabilities.

INTRODUCTION: We sought to identify patient understanding of urology residents and comfort with being cared for by residents. Through this pilot study, we aim to propose educational objectives to improve this knowledge gap and ultimately allow for an improved patient experience. METHODS: A prospective survey was distributed from September 2022 to October 2022. A patient knowledge about residents (KAR) score was calculated by combining correct responses to 5 questions (maximum = 5). Another score evaluating patient opinion of residents was calculated using Likert scale questions (range 3-19; higher scores correlate with positive opinion) denoting patient outlook on residents. RESULTS: A total of 88 surveys were completed. The average ± SD patient age was 62.7 ± 15.2 years. Patients previously seen by a resident had significantly higher KAR scores (3.591 ± 1.210) compared to patients never interacting with a resident or unsure (KAR = 2.381 ± 1.324; P < .0001). Additionally, those with higher levels of education had greater KAR scores (graduate-level KAR = 3.792 ± 1.179; P = .002). No variables were found to have a statistically significant impact on patients' average opinion of residents. CONCLUSIONS: Current patient understanding of the role of a urology resident is suboptimal. Given this knowledge gap, we hope to propose educational approaches to help aid in patient understanding of resident physicians, who play a critical role in their clinical care.

Single port (SP) robotic pyeloplasty in a pediatric patient.

We began using the da Vinci single port (SP) robot for pediatric urologic surgeries at our institution due to limited access to the multiport robot. Availability of this technology has allowed us to schedule cases in a timelier fashion and increase access to minimally invasive urologic surgery for children in our area. Here, we report our technique for transperitoneal SP robotic pyeloplasty in the case of a 7 year-old boy with left ureteropelvic junction obstruction. Our technique was refined over a series of 10 patients under the age of 18. Highlights of the SP RALP technique include one 3 cm, concealed incision over the pubic tubercle, gentle frog leg positioning and burping of the boom to create optimal angle for robotic docking, and use of a "floating dock" to obtain 10 cm distance from target anatomy which is essential in smaller pediatric patients. SP pyeloplasty is safe and feasible in children and offers a concealed single incision alternative to the multiport approach.

An alternative approach of cystoscopy-guided removal of a recalcitrant foley catheter.

Foley balloon malfunction can result in recalcitrant catheters. Management approaches for troubleshooting this rare occurrence have been described in the literature, including the more invasive methods such as the use of cystoscopy for direct visualization. We describe a case of our endourologic management of a retained 14F temperature-probe foley catheter in a fifty-nine-year-old female patient.

Ureteral fibroepithelial polyp: A diagnostic challenge.

Ureteral fibroepithelial polyps (UFP) are relatively rare, benign tumors. A total of 236 total cases were documented between 1932 and 2013. Notably, imaging studies, including computerized tomography (CT) and magnetic resonance imaging (MRI) are often negative. This report details a case of a patient with a UFP who presented with hematuria. CT suggested a possible 1.8 cm mass, but subsequent MRI was negative. Cystoscopy showed a polyp that prolapsed out of the left ureter and into the bladder with peristalsis. The patient subsequently underwent retrograde ureteroscopy and holmium laser excision of the polyp.

Inverted urothelial papilloma: A case report.

Inverted urothelial papilloma (IUP) is an unusual tumor that typically presents as a non-invasive, endophytic urothelial neoplasm. Though fairly well described in the bladder, IUP of the upper urinary tract is fairly rare, with only 68 cases documented in English language literature. Our patient presented with an IUP of the distal left ureter and was treated with a distal ureterectomy and reimplant of the ureter with a psoas hitch.

Multi-Institutional Outcomes of Endoscopic Management of Stricture Recurrence after Bulbar Urethroplasty.

PURPOSE: Approximately 10% to 20% of patients will have a recurrence after urethroplasty. Initial management of these recurrences is often by urethral dilation or direct vision internal urethrotomy. In the current study we describe the outcomes of endoscopic management of stricture recurrence after bulbar urethroplasty. MATERIALS AND METHODS: We retrospectively reviewed bulbar urethroplasty data from 5 surgeons in the TURNS (Trauma and Urologic Reconstruction Network of Surgeons). Men who underwent urethral dilation or direct vision internal urethrotomy for urethroplasty recurrence were identified. Recurrence was defined as the inability to pass a 17Fr cystoscope through the area of reconstruction. The primary outcome was the success rate of recurrence management. Comparisons were made between urethral dilation and direct vision internal urethrotomy, and then between endoscopic management of recurrences after excision and primary anastomosis urethroplasty vs substitutional repairs using time to event statistics. RESULTS: In 53 men recurrence was initially managed endoscopically. Median time to urethral stricture recurrence after urethroplasty was 5 months. At a median followup of 5 months the overall success rate was 42%. Success after urethral dilation was significantly less than after direct vision internal urethrotomy (1 of 10 patients or 10% vs 21 of 43 or 49%, p <0.001) with a failure HR of 3.15 (p = 0.03). Direct vision internal urethrotomy was more effective after substitutional failure than after excision and primary anastomosis urethroplasty (53% vs 13%, p = 0.005). CONCLUSIONS: Direct vision internal urethrotomy was more successful than urethral dilation in the management of stricture recurrence after bulbar urethroplasty. Direct vision internal urethrotomy was more successful in patients with recurrence after substitution urethroplasty compared to after excision and primary anastomosis urethroplasty. Perhaps this indicates a different mechanism of recurrence for excision and primary anastomosis urethroplasty (ischemic) vs substitution urethroplasty (nonischemic).

Donor-recipient size matching and survival after lung transplantation. A cohort study.

RATIONALE: The association between a high predicted total lung capacity (pTLC) ratio (equal to pTLC(donor)/pTLC(recipient)), suggestive of an oversized allograft, with improved survival after lung transplantation (LTx) remains controversial. OBJECTIVES: To characterize donor-recipient lung size matching based on the pTLC ratio and to investigate the relationship of the pTLC ratio with post-LTx survival. METHODS: All subjects in the Scientific Registry of Transplant Recipients, who underwent first-time LTx in the lung allocation score-based system between May 4, 2005 and March 31, 2012, were studied, and the pTLC ratio was calculated on the basis of sex, height, and age. Risk of death after LTx was analyzed using Cox proportional hazards models. MEASUREMENTS AND MAIN RESULTS: The pTLC ratio was available for 10,289 of the 10,318 study subjects (99.7%). The mean pTLC ratio was 1.015 ± 0.175 (interquartile range, 0.918-1.119). Univariate analysis showed that the pTLC ratio was strongly associated with death in the first LTx year (P < 0.0001). With the pTLC ratio entered as a spline there was a nonlinear association with declining risk of death with higher pTLC ratio from 0.5 to about 1.3, where an inflection occurred with rising risk at higher values. Accounting for the pTLC ratio, recipient and donor sex were not independently associated with death after LTx. A change of pTLC ratio from 0.918 to 1.119 (the interquartile range) was associated with similar point estimates of reduced risk of death at 1 year in univariate (hazard ratio, 0.78) and comprehensive risk-adjusted multivariate models (hazard ratio, 0.86). CONCLUSIONS: The pTLC ratio is an independent predictor of death in the first year after LTx and explains the association of sex with survival after LTx. Incorporating the pTLC ratio in the lung allocation mechanism could improve outcomes after LTx.
