RESUMO

Objectives: To explore beliefs and practice patterns of urologists regarding intrarenal pressure (IRP) during ureteroscopy (URS). Methods: A customized questionnaire was designed in a 4-step iterative process incorporating a systematic review of the literature and critical analysis of topics/questions by six endourologists. The 19-item questionnaire interrogated perceptions, practice patterns, and key areas of uncertainty regarding ureteroscopic IRP, and was disseminated via urologic societies, networks, and social media to the international urologic community. Consultants/attendings and trainees currently practicing urology were eligible to respond. Quantitative responses were compiled and analyzed using descriptive statistics and chi-square test, with subgroup analysis by procedure volume. Results: Responses were received from 522 urologists, practicing in six continents. The individual question response rate was >97%. Most (83.9%, 437/515) respondents were practicing at a consultant/attending level. An endourology fellowship incorporating stone management had been completed by 59.2% (307/519). The vast majority of respondents (85.4%, 446/520) scored the perceived clinical significance of IRP during URS ≥7/10 on a Likert scale. Concern was uniformly reported, with no difference between respondents with and without a high annual case volume (p = 0.16). Potential adverse outcomes respondents associated with elevated ureteroscopic IRP were urosepsis (96.2%, 501/520), collecting system rupture (80.8%, 421/520), postoperative pain (67%, 349/520), bleeding (63.72%, 332/520), and long-term renal damage (26.1%, 136/520). Almost all participants (96.2%, 501/520) used measures aiming to reduce IRP during URS. Regarding the perceived maximum acceptable threshold for mean IRP during URS, 30 mm Hg (40 cm H2O) was most frequently selected [23.2% (119/463)], with most participants (78.2%, 341/463) choosing a value ≤40 mm Hg. Conclusions: This is the first large-scale analysis of urologists' perceptions of ureteroscopic IRP. It identifies high levels of concern among the global urologic community, with almost unanimous agreement that elevated IRP is associated with adverse clinical outcomes. Equipoise remains regarding appropriate IRP limits intraoperatively and the most appropriate technical strategies to ensure adherence to these.

RESUMO

OBJECTIVES: To perform a multi-institutional investigation of incidence and outcomes of urethral trauma sustained during attempted catheterization. PATIENTS & METHODS: A prospective, multi-center study was conducted over a designated 3-4 month period, incorporating seven academic hospitals across the UK and Ireland. Cases of urethral trauma arising from attempted catheterization were recorded. Variables included sites of injury, management strategies and short-term clinical outcomes. The catheterization injury rate was calculated based on the estimated total number of catheterizations occurring in each center per month. Anonymised data were collated, evaluated and described. RESULTS: Sixty-six urethral catheterization injuries were identified (7 centers; mean 3.43 months). The mean injury rate was 6.2 ± 3.8 per 1000 catheterizations (3.18-14.42/1000). All injured patients were male, mean age 76.1 ± 13.1 years. Urethral catheterization injuries occurred in multiple hospital/community settings, most commonly Emergency Departments (36%) and medical/surgical wards (30%). Urological intervention was required in 94.7% (54/57), with suprapubic catheterization required in 12.3% (n = 7). More than half of patients (55.56%) were discharged with an urethral catheter, fully or partially attributable to the urethral catheter injury. At least one further healthcare encounter on account of the injury was required for 90% of patients post-discharge. CONCLUSIONS: This is the largest study of its kind and confirms that iatrogenic urethral trauma is a recurring medical error seen universally across institutions, healthcare systems and countries. In addition, urethral catheter injury results in significant patient morbidity with a substantial financial burden to healthcare services. Future innovation to improve the safety of urinary catheterization is warranted.

RESUMO

OBJECTIVES: Systemic lupus erythematosus and granulomatosis with polyangiitis are systemic inflammatory conditions associated with renalfailure that can recur after renal transplant. Patients with these conditions are treated with chronic immunosuppression, potentially increasing risk of secondary malignancies. Here, we investigated long-term outcomes in renal transplant recipients with these conditions. MATERIALS AND METHODS: Transplant recipients with end-stage kidney disease due to systemic lupus erythematosus and granulomatosis with polyangiitis seen between 1982 and 2016 at a national kidney transplant center were included. Primary outcome variables were long-term allograft survival and incidence of secondary malignancy. Secondary outcome measures were incidence of delayed graft function, primary disease recurrence, and serum creatinine at follow-up. RESULTS: Ninety-eight transplant procedures (90 from deceased donors) in 92 consecutive patients (mean age 42.3 ± 14.4 y) were included: 55 with systemic lupus erythematosus and 37 with granulomatosis with polyangiitis. Follow-up duration was 110.53 ± 81.95 months (range, 1-393 mo). Overall renal allograft survival was 94.7% at 1 year, 85.4% at 5 years, and 75.4% at 10 years posttransplant. Patientswith systemic lupus erythematosus showed overall allograft survival of 91.6% at 1 year, 84.3% at 5 years, and 74.4% at 10 years. There was 1 allograft failure due to recurrence of primary disease in this group. Patients with granulomatosis with polyangiitis showed overall allograft survival of 100% at 1 year, 92.4% at 5 years, and 92.4% at 10 years. There were 21 mortalities, with 5 (23.8%) due to secondary malignancy. In total, 46 malignancies were diagnosed in 31 patients. CONCLUSIONS: We found excellent long-term renal allograft survival rates in patients with systemic lupus erythematosus and granulomatosis with polyangiitis, with secondary malignancy rates similar to those shown in recipients without autoimmune diseases. These findings provide clinicians with long-term data on transplant recipients with end-stage renal failure due to systemic inflammatory conditions.

RESUMO

INTRODUCTION: Surgery performed later in the week has been associated with longer length of stay (LOS). The aim of this study was to assess if the day of the surgery impacted the LOS for two major urological procedures in a tertiary referral university teaching hospital. METHODS: A retrospective review was performed of two major urological procedures consecutively performed by a single surgeon in our unit from March 2012 to December 2015. Patient demographics, histopathological characteristics, operative details, and LOS were obtained from the patients' medical records. Procedures performed on Monday or Tuesday were defined as early in the week and procedures performed on Wednesday, Thursday, or Friday were defined as late in the week. RESULTS: During the study period, 140 open radical prostatectomy (ORP) and 42 open partial nephrectomy (OPN) procedures were performed. There was a significant difference in median LOS for major urological procedures performed early in the week compared to late in the week (3 [3-4] days vs. 4 [4-5] days; p= 0.0001). There was a significant difference in median LOS for ORP performed early in the week compared to late in the week (3 [3-4] days vs. 4 [4-5] days; p= 0.0004). There was a similar significant difference in OPN performed early in the week compared to late in the week (4 [3-5.5] days vs. 5 [4-5] days; p= 0.029). CONCLUSIONS: The day of surgery impacts LOS for major urological procedures. Major procedures should be performed early in the week, when it is feasible to facilitate prompt safe discharge and better use of hospital resources.

RESUMO

BACKGROUND: Currently, there is no standardised screening for prostate cancer in Europe. Assessment of risk is opportunistically undertaken in consultation with the GP or urologist. Evaluation of the prostate gland consists of a prostate-specific antigen (PSA) serum level and a digital rectal examination (DRE) of the gland. DRE is an essential part of the assessment that can independently predict prostate cancer in the setting of a normal PSA level. AIM: To evaluate the clinical usefulness of the DRE in general practice and urology clinics, and to ascertain its positive predictive value and sensitivity. DESIGN AND SETTING: A retrospective analysis study of a cohort of Irish men who underwent TRUS guided biopsy of the prostate in a single Irish tertiary referral centre, despite a normal PSA level. Patients were identified from a Rapid Access Prostate Clinic patient database. Pathological biopsy results were correlated with clinical DRE findings. METHOD: Patient demographics, PSA levels, and DRE findings from a prospectively established database and hospital data systems from May 2009 to October 2013 were analysed. RESULTS: Of 103 men referred over a 53-month period with a normal age-adjusted PSA level, 67% were referred on the basis of an abnormal DRE alone. Thirty-five per cent of males with a normal PSA had prostate cancer. DRE alone had a sensitivity and specificity of 81% and 40% respectively in diagnosing prostate cancer, with a positive predictive value of 42%. Seventy-six per cent of these men had high-grade disease. CONCLUSION: DRE is a key part of the assessment for prostate cancer. It can independently identify patients at risk of prostate cancer, with a substantial proportion of these having clinically significant disease requiring treatment. This study reinforces the importance of DRE in the primary care setting in the assessment for prostate cancer. An abnormal DRE, even in the setting of a normal PSA level, necessitates referral.
