RESUMO

BACKGROUND: We sought to determine if participating in a surgical training session using perfused fresh human cadavers (PFHC) had a positive effect on urology residents' confidence in performing open and endoscopic procedures. METHODS: Urology residents at our institution participated in a surgical training session in the West Virginia University Fresh Tissue Training Program, which utilized fresh cadavers with vascular perfusion. The session consisted of performing different urologic procedures (open and endoscopic) on the perfused fresh human cadavers (PFHC). Residents were given a survey to rate their confidence in different urologic procedures before, after, and 6 months after the session. Each procedure on the survey had 3-6 questions associated with it, with scores ranging from 0 (no confidence) to 4 (great confidence). Scores for each procedure before and after the session were compared. RESULTS: Six residents participated in the session. There was an increase in the score for every procedure performed after the session. Scores at 6 month follow up remained higher than the pre-session scores. CONCLUSION: PFHCs offer an excellent opportunity to teach a wide variety of urologic procedures to residents. Incorporation of PFHCs may be very useful in urologic training, and further studies on its use are warranted.

RESUMO

OBJECTIVE: To analyse whether selective arterial clamping (SAC) and off-clamp (OC) techniques during robot-assisted partial nephrectomy (RPN) are associated with a renal functional benefit in patients with Stage 3-5 chronic kidney disease (CKD). PATIENTS AND METHODS: The change in estimated glomerular filtration rate (eGFR) over time was compared between 462 patients with baseline CKD 3-5 that underwent RPN with main arterial clamping (MAC) (n = 375, 81.2%), SAC (n = 48, 10.4%) or OC (n = 39, 8.4%) using a multivariable linear mixed-effects model. All follow-up eGFRs, including baseline and follow-up between 3 and 24 months, were included in the model for analysis. The median follow-up was 12.0 months (interquartile range 6.7-16.5; range 3.0-24.0 months). RESULTS: In the multivariable linear mixed-effects model adjusting for characteristics including tumour size and the R.E.N.A.L. (Radius; Exophytic/Endophytic; Nearness; Anterior/Posterior; Location) Nephrometry Score, the change in eGFR over time was not significantly different between SAC and MAC RPN (ß = -1.20, 95% confidence interval [CI] -5.45, 3.06; P = 0.582) and OC and MAC RPN (ß = -1.57, 95% CI -5.21, 2.08; P = 0.400). Only 20 (15 MAC, two SAC, three OC) patients overall had progression of their CKD stage at last follow-up. The mean ischaemia time was 17 min for MAC and 15 min for SAC. There was no benefit to SAC or OC in terms of blood loss, perioperative complications, length of stay, or surgical margins. CONCLUSION: SAC and OC techniques during RPN were not associated with benefit in preservation of eGFR in patients with baseline CKD.

RESUMO

OBJECTIVE: Utilization of partial nephrectomy (PN) for T2 renal mass is controversial due to concerns regarding burden of morbidity, though most cited data are from open PN (OPN). We compared surgical quality and functional outcomes of RPN and OPN for clinical T2a renal masses (cT2aRM). METHODS: Retrospective analysis of 150 consecutive patients [RPN 59/OPN 91] who underwent PN from July 2008 to June 2016. Main outcome was achievement of Trifecta [negative surgical margin, no major urologic complications, and ≥90% preservation of estimated glomerular filtration rate (eGFR)]. Multivariable analysis was performed to identify factors of Trifecta attainment. RESULTS: Mean tumor size (RPN 7.9 vs. OPN 8.4 cm, p = 0.139) and median RENAL score (p = 0.361) were similar. No difference was noted for positive margins (RPN 3.4% vs. OPN 1.1%, p = 0.561), ΔeGFR (RPN - 6.2 vs. OPN - 7.8, p = 0.543), and ≥ 90% eGFR recovery (RPN 54.1% vs. OPN 47.2%, p = 0.504). RPN had lower blood loss (p = 0.015), hospital stay (p = 0.013), and Clavien ≥ 3 complications (RPN 5.1% vs. OPN 16.5%, p = 0.041). Trifecta rate was significantly higher in RPN (47.5% vs. 34.0%, p = 0.041). Multivariable analysis demonstrated decreasing RENAL score (OR 1.11, p < 0.001), RPN (OR 1.2, p = 0.013), and decreasing EBL (OR 1.02, p = 0.016) to be associated with Trifecta attainment. CONCLUSIONS: RPN provided similar functional and oncologic precision to OPN, while being associated with improvements in major complications, the latter of which was reflected in a higher rate of Trifecta achievement for RPN. RPN may be considered to be a first-line option for select patients with cT2aRM when feasible and safe.

RESUMO

Background and Objective: Male stress urinary incontinence (SUI) and erectile dysfunction (ED) are well established diagnoses within Men's Health, often more specifically within the prostate cancer survivorship cohort. Taken individually, well defined treatment algorithms exist with which many surgeons are comfortable; however, treatment of both in a single setting or staged fashion introduces complexity. Emerging treatment options also exist, and there is immature or minimal data when these are combined with inflatable penile prosthesis (IPP) insertion, radiation history, and/or variable degrees of incontinence. Our objective was to describe and summarize the currently available treatment options for SUI particularly at the time of IPP insertion. Methods: A literature review was performed to summarize contemporary treatment of SUI at time of IPP placement. Anecdotal experience was added from high volume, subspecialty trained Men's Health and Reconstructive Urologists. Key Content and Findings: Non-invasive approaches such as pelvic floor muscle training (PFMT), behavioral modification, and external compression devices play some limited role in treatment and/or management of SUI, particularly in the early post operative period, or for those unwilling or unable to undergo more definitive intervention. More invasive options such as artificial urinary sphincter (AUS) implantation, male sling, or other implantable devices are more appropriate for good surgical candidates with higher bother and/or more severe incontinence. These options can be concomitant or staged relative to IPP placement. Climacturia, particularly with mild or no bothersome SUI, can successfully be addressed at the time of penile prosthesis placement with the utilization of the Mini-Jupette suburethral sling. Conclusions: A variety of treatment options exist for concomitant treatment of SUI at time of IPP, and both safety and efficacy have been demonstrated for many in the same operative setting. As with treatment of ED or SUI in isolation, patient selection, careful counseling, and management of expectations can lead to high patient satisfaction.

RESUMO

INTRODUCTION: Double-diaper technique with an open-drainage catheter is a common practice after hypospadias repair. However, double-diapering may increase the burden of postoperative care and has not been compared to single-diapering with an open-drainage catheter. OBJECTIVES: This study investigates whether the single-diaper technique is associated with inferior surgical outcomes compared to the double-diaper technique. MATERIALS AND METHODS: A single surgeon database was retrospectively reviewed for patients who underwent hypospadias repair between 2013 and 2021. Patients who were lost to follow-up and those in whom the type of diaper care (single- or double-diaper) was not documented were excluded. Patients in the single-diaper technique received the same type of dressing and discharge instructions, as those in the double-diaper group, except for leaving the catheter freely draining into a single-diaper. Short-term complications including surgical site infection (SSI), urinary tract infection (UTI) and wound dehiscence, were the primary outcome; whereas the long-term urethroplasty complications (urethrocutaneous fistula and meatal stenosis) were secondary outcomes. Outcomes were analyzed according to the type of diaper care. RESULTS: Among 323 patients reviewed, 219 patients met the inclusion criteria (72 patients in the double-diaper and 147 in the single-diaper group). Both study groups were similar regarding patient demographics, hypospadias characteristics and surgical technique. Looking at the primary outcomes, there was no statistically significant difference in SSI, UTI or wound dehiscence. For the secondary outcomes, the incidence of meatal stenosis (8.3 vs. 1.4%, p = 0.044), and fistula formation (15.3% vs 5.4%, p = 0.037) was significantly higher in the double-diaper than the single-diaper group, respectively (Table 2). CONCLUSION: Single-diaper technique following hypospadias repair is not associated with increased risk of complications compared to double-diaper technique.

RESUMO

Inferior vena cava filters are effective for the management of thromboembolic disease but can erode into adjacent organ systems in rare instances. Endovascular retrieval of eroded filters has been the preferred management for this complication. We present a case for which endovascular retrieval was not appropriate because of filter orientation and erosion into the ureter and describe successful management using open retrieval of a permanent filter with erosion into the renal collecting system requiring reconstruction. Although minimally invasive retrieval is preferred over open repair, this approach should be considered when filter erosion is not amenable to endovascular retrieval.

RESUMO

Prostate cancer patients routinely undergo surveillance for recurrence using prostate-specific antigen (PSA). While PSA's benefit in screening is controversial, its use for detecting recurrence in patients with history of prostate cancer is pivotal. Rising PSAs with the newly advanced prostate-specific membrane antigen positron emission tomography (PSMA PET) can help localize the location of recurrences for better excision and management. Here, we present a 55-year-old with prostate cancer, with initially undetectable postprostatectomy PSA levels, who later presented with a PSA of 3.47 ng/mL. PSMA PET showed isolated uptake in an abdominal wall mass. Pelvic lymphadenectomy and abdominal wall mass excision were performed, confirming a single metastasis in an abdominal wall lymph node. Metastasectomy led to a dramatic drop in PSA to 0.10 ng/mL both postoperatively and on long-term follow-up. Our case illustrates the potential benefit of metastasis-directed therapy in delayed oligometastasis following definitive management of prostate cancer.

RESUMO

Objectives: To identify cystourethrogram (CUG) findings that independently predict the outcome of posterior urethroplasty (PU) following pelvic fracture urethral injury (PFUI). Methods: Findings of CUG included the location of the proximal end of the bulbar urethra in zones A (superficial) or B (deep) according to its relationship with the pubic arch. Others included the presence of pelvic arch fracture, bladder neck, and posterior urethral appearance. The primary outcome was the need for reintervention either endoscopically or by redo urethroplasty. Independent predictors were modeled using a logistic regression model and a nomogram was constructed and internally validated using 100-bootstrap resampling. Time-to-event analysis was performed to validate the results. Results: A total of 196 procedures in 158 patients were analyzed. The success rate was 83.7% with 32 (16.3%) procedures requiring direct vision internal urethrotomy, urethroplasty, or both in 13 (6.6%), 12 (6.1%), and 7 (3.6%) patients, respectively. On multivariate analysis, bulbar urethral end located at zone B (odds ratio [OR]: 3.1; 95% confidence interval [CI]: 1.1-8.5; p = 0.02), pubic arch fracture (OR: 3.9; 95%CI: 1.5-9.7; p = 0.003), and previous urethroplasty (OR: 4.2; 95% CI: 1.8-10.1; p = 0.001) were independent predictors. The same predictors were significant in the time-to-event analysis. The nomogram discrimination was 77.3% and 75% in the current data and after validation. Conclusions: The location of the proximal end of the bulbar urethra and redo urethroplasty could predict the need for reintervention after PU for PFUI. The nomogram could be used preoperatively for patient counseling and procedure planning.

RESUMO

Bladder cancer is rare in children, with 86.8% of pediatric patients diagnosed not carrying any of the common risk factors commonly seen in adults. Here, a 16-year-old female presented to the ED with in urinary retention. A renal bladder ultrasound revealed an echogenic focus in the bladder wall. On diagnostic cystoscopy a small papillary bladder lesion was appreciated and resected. Final pathology of the bladder mass resulted as non-invasive low grade papillary urothelial carcinoma (pTa). This report demonstrates bladder cancer in the pediatric age group, and should be considered as a possible differential diagnosis in patients with dysfunctional voiding.

RESUMO

Angiomyolipoma (AML) is a benign renal tumor usually found incidentally. Rarely, AML can present with renal colic due to urinary tract obstruction. Prior cases of obstructing AML have been presented and managed successfully with surgical removal. Selective angioembolization has emerged as an alternative management strategy for AML, but no documented cases have been presented for this strategy in the setting of obstruction. Here, we present a case of obstructing AML treated with selective angioembolization with subsequent resolution of obstruction.

RESUMO

Introduction: Clinically node-positive non-metastatic bladder cancer (cN+) has been the target of several studies aiming to establish a standard of care for this population. Limited studies have shown a survival benefit for various multimodal therapy approaches. The role of radiation therapy has not been well established. Our study aims to study the trends of the reported treatment options offered to patients with cN+ bladder cancer in a national database and to evaluate the effect of various treatments, including radiation, on survival. Methods: The National Cancer Database (NCDB) was used to identify cN+ bladder cancer patients who received chemotherapy alone or in combination with radical cystectomy (RC) or radiotherapy. 3,481 patients were included and divided into 4 groups: chemotherapy only, chemotherapy and RC, chemotherapy and radiation therapy, and chemotherapy, RC, and radiation therapy. Demographic data was compared using ANOVA for continuous variables, and Chi-square for categorical variables. Multivariable analysis was done to compare groups using a multinomial logistic regression model. Kaplan-Meier test was used for survival analysis and Cox-Regression was used for multivariable survival analysis. Results: Patients undergoing RC were significantly younger (P <0.001). There was a significant difference between the groups regarding racial distribution, facility-type and insurance status. There was no difference in gender, Charlson\Deyo score, financial or educational status. Patients who underwent combination therapy with chemotherapy and RC were found to have the longest median survival time at 27 months. Multivariable analysis showed that final treatment, age, sex, Charlson\Deyo comorbidity score, TNM edition and facility-type were significant survival predictors. Race, insurance and financial status failed to maintain significance. There was no survival difference between the chemotherapy group and chemo-radiotherapy group. Conclusions: The combination of surgery and chemotherapy achieves statistically significant superior survival in cN+ bladder cancer. Adding radiotherapy to chemotherapy did not improve survival in this group of patients.

RESUMO

We present a case of severe acute variceal bleeding in an ileal conduit stoma successfully managed with trans-hepatic trans-portal selective angioembolization as a lifesaving measure. Despite repeated transfusions, the patient's hemoglobin continued to be unstable. The patient underwent transhepatic embolization of ileal stoma varicose veins. Angioembolization was followed up with excision of ileal conduit stoma and creation of cutaneous ureterostomy for definitive treatment management of hemorrhage. In conclusion, trans-hepatic trans-portal embolization is an effective option for management of severe acute variceal bleeding in an ileal conduit stoma as a lifesaving measure and can be followed by excision of the conduit.

RESUMO

BACKGROUND: The aim of this study was to evaluate the association between tumor complexity based on RENAL nephrometry score and complications. METHODS: We retrospectively identified 2555 patients who underwent RPN for renal cell carcinoma. Major complication was defined as Clavien Grade ≥3. The relationship between baseline demographic, clinical characteristics, perioperative and postoperative outcomes, and tumor complexity were assessed using χ2 test of independence, Fisher's Exact Test and Kruskal Wallis Test. An unadjusted and adjusted logistic regression model was used to assess the relationship between major complication and demographic, clinical characteristics, and perioperative outcomes. RESULTS: There was a significant relationship between tumor complexity and WIT (P<0.001), operative time (P<0.001), estimated blood loss (P<0.001), and major complication (P=0.019). However, there was no relationship with overall complications (P=0.237) and length of stay (LOS) (P=0.085). In the unadjusted model, higher tumor complexity was associated with major complication (P=0.009). Controlling for other variables, there was no significant difference between major complication and tumor complexity (low vs. moderate, P=0.142 and high, P=0.204). LOS (P<0.001) and operative time (P=0.025) remained a significant predictor of major complication in the adjusted model. CONCLUSIONS: Tumor complexity is not associated with an increase in overall or major complication rate after RPN. Experience in high-volume centers is demonstrating a standardization of low complications rates after RPN independent of tumor complexity.

RESUMO

BACKGROUND: The American Urological Association published guidelines in 2014 regarding management of undescended testicles (UDT). Despite these guidelines, prior studies have indicated discordance between guidelines and actual practice, especially in rural states. This study aims to identify if educating referring providers improves management of UDT. METHODS: Patients with UDT referred to our institution were divided into two groups: those referred prior to (Group 1) and after (Group 2) targeted education. A retrospective review was performed to compare the groups in terms of age at time of referral and surgery, laterality, specialty, and practice setting of referring provider, and whether or not ultrasound (US) was performed prior to referral. RESULTS: A total of 100 patients were identified in Group 1 and 168 in Group 2. No significant differences were noted between groups regarding age, variability of referring provider, or those receiving US prior to referral. Median age at referral was 20.7 months (range=0-194) and 33 months (range=0-205.1) in Groups 1 and 2, respectively (p=0.26). Sixty-two (37%) patients underwent surgical evaluation within 18 months of age or younger in Group 1 compared to 39 (39%) in Group 2 (p=0.73). Private practice pediatricians comprised the majority of referring providers in both cohorts. US was performed prior to referral in 41% of patients in Group 1 compared to 35.8% in Group 2 (p=0.51). The number of US ordered prior to referral significantly decreased from 10 (50%) to six (19%) following education among academic providers (p=0.02). No significant difference was found following education for private practice physicians (p=0.27). CONCLUSION: Targeted education did not improve age at referral in the short-term, which may reflect suboptimal healthcare access. Additionally, more research is needed to evaluate whether more diverse targeted education provided on a regular basis to both physician and mid-level providers would have a meaningful impact.

RESUMO

Diphallia is an exceedingly rare anomaly characterized by partial or complete duplication of the phallus. Approximately 100 cases have been reported worldwide since its initial documentation, and incidence is estimated at 1 in 5 to 6 million live births. Therapeutic management is dependent on the extent of the anomaly, ranging from phallic excision to complex reconstructive procedures in cases of broader systemic involvement. We present the case of congenital true diphallia with associated penoscrotal transposition, bifid scrotum, partial urethral duplication, ventral chordee, large scrotal lipoma and sacral dimple. We further present a review of available literature pertaining to diphallia.

RESUMO

PURPOSE: To address whether preoperative tamsulosin increases the rate of successful ureteral orifice navigation for ureteroscopy (URS) without prestenting in school-age pediatric patients. METHODS: We retrospectively reviewed all pediatric patients who had undergone ureteroscopy (URS) at our institution from 2013 to 2020. Patients were divided into two groups: those who had received tamsulosin 0.4 mg daily ≥48 hours preoperatively and those who had not. Statistical analysis was done using independent-sample t-tests and Mann-Whitney U tests for continuous variables, and χ2 and Fisher's exact tests were used for categorical variables. Multivariate analysis was done using binary logistic regression test. RESULTS: Overall, successful ureteral orifice navigation occurred in 44 of 50 patients (88%) who had received tamsulosin and 17 of 26 (65.4%) who had not (p=0.019). On further subanalysis based on stone location and instrumentation used, successful ureteral orifice navigation had occurred in 21 of 24 patients (87.5%) in the tamsulosin group and one of five (20%) in the no-tamsulosin group for semirigid ureteroscopy for mid-distal ureterolithiasis (p=0.007). For proximal ureteral and renal stones, successful ureteral orifice navigation with a flexible ureteroscope or ureteral access sheath had occurred in 23 of 26 patients (88.5%) in the tamsulosin group and 16 of 21 (76.2%) in the no-tamsulosin group (p=0.437). Multivariate analysis showed no significant difference between success rates in the two groups after controlling for patient weight, height, BMI, and stone location. We did not observe any adverse effects from tamsulosin. CONCLUSION: This is the first study to evaluate preoperative tamsulosin on successful ureteral orifice navigation in school-age pediatric patients. Although not reaching statistical significance, further evaluation should be done on larger cohorts. Patient height was found to be an independent predictor of successful ureteral orifice navigation.

RESUMO

OBJECTIVE: To analyze the volumetric changes of the ipsilateral and contralateral kidneys and their effect on functional outcome post partial nephrectomy using segmentation analysis. PATIENTS AND METHODS: We have analyzed the data of 119 patients from a single surgeon series of partial nephrectomy patients. Median follow-up was 11.40 months. Patients with bilateral tumors, and solitary kidney were excluded from analysis. Volumetric measurements were performed using a semiautomated tissue segmentation tool. A simple linear regression model to assess the predictors for parenchymal volume loss (PVL). A multivariable linear regression model was used to evaluate the association between PVL and warm ischemia time (WIT), controlling for other factors. RESULTS: Mean WIT was 12.09 ± 4.40 minutes and the mean percentage decrease in the volume of the operated kidney was 16.99 ± 13.49%. WIT (ß = 1.24, P < 0.001) and tumor complexity (simple vs. intermediate, ß = 0.06, P = 0.984; simple vs. high, ß = 11.62,P = 0.007) were associated with PVL. A 1 minute increase in WIT was associated with an increase in the percentage volume loss in the operated kidney by 1.38% (ß = 1.20, P < 0.001). Patients with high tumor complexity (ß = 11.17, P = 0.009) had a significantly higher percentage volume loss compared to patients with simple tumor complexity. Ipsilateral PVL (ß = -0.35, P = 0.015) and male gender (ß = -9.89, P = 0.021) were associated with change in eGFR. After adjusting for confounders, % volume loss (ß = -0.32, P < 0.001) remained a significant predictor for contralateral hypertrophy. CONCLUSION: Tumor complexity results in higher WIT and increased PVL as measured by volumetric segmentation. PVL is a key factor associated with functional outcome, and is directly linked to WIT. Increased PVL is also associated with decreased contralateral hypertrophy. Prospective studies with larger samples sizes will be required to validate our findings.

RESUMO

Background: To investigate the incidence, timing, and risk factors of venous thromboembolic events (VTE) following radical cystectomy and urinary diversion in a large cohort of patients.Patients and Methods: The electronic data base of patients underwent radical cystectomy and urinary diversion in a tertiary referral center between January 2004 and February 2014 was retrospectively reviewed. Patients developed VTE namely deep vein thrombosis (DVT) and pulmonary embolism (PE) within 90 days after surgery were identified and compared to those without VTE. Univariate and multivariate analyses were used to evaluate the predictors of the VTE.Results: Out of 1737 patients, 77 VTE have occurred in 70 (4%) patients. DVT and PE occurred in 34 (2%) and 43 (2.5%) patients, respectively. PE was the leading cause of mortality in 17 patients. The median (range) time for VTE was 11 days (1-92) with 39 (50.6%) events developed after the stoppage of thrombo-prophylaxis. On multivariate analysis, older age ≥60 years (OR = 1.9; p = 0.009), female gender (OR = 1.9; p = 0.02), morbid obesity (BMI ≥35 kg/m2) (OR = 2.4; p = 0.008) and preoperative platelet count (≥300.000/cc) (OR = 1.6; p = 0.045) were significant predictors for developing VTE.Conclusion: The overall incidence of VTE is 4% with more than half of events occurred after the stoppage of thromboprophylaxis highlighting the necessity of adopting an extended protocol. Independent predictors included older age, female gender, morbid obesity and preoperative thrombocytosis. These group of patients require particular attention for the prevention of this complication.
