RESUMO

BACKGROUND: Clinically significant CKD following surgery for kidney cancer is associated with increased morbidity and mortality, but identifying patients at increased CKD risk remains difficult. Simple methods to stratify risk of clinically significant CKD after nephrectomy are needed. METHODS: To develop a tool for stratifying patients' risk of CKD arising after surgery for kidney cancer, we tested models in a population-based cohort of 699 patients with kidney cancer in Queensland, Australia (2012-2013). We validated these models in a population-based cohort of 423 patients from Victoria, Australia, and in patient cohorts from single centers in Queensland, Scotland, and England. Eligible patients had two functioning kidneys and a preoperative eGFR ≥60 ml/min per 1.73 m2. The main outcome was incident eGFR <45 ml/min per 1.73 m2 at 12 months postnephrectomy. We used prespecified predictors-age ≥65 years old, diabetes mellitus, preoperative eGFR, and nephrectomy type (partial/radical)-to fit logistic regression models and grouped patients according to degree of risk of clinically significant CKD (negligible, low, moderate, or high risk). RESULTS: Absolute risks of stage 3b or higher CKD were <2%, 3% to 14%, 21% to 26%, and 46% to 69% across the four strata of negligible, low, moderate, and high risk, respectively. The negative predictive value of the negligible risk category was 98.9% for clinically significant CKD. The c statistic for this score ranged from 0.84 to 0.88 across derivation and validation cohorts. CONCLUSIONS: Our simple scoring system can reproducibly stratify postnephrectomy CKD risk on the basis of readily available parameters. This clinical tool's quantitative assessment of CKD risk may be weighed against other considerations when planning management of kidney tumors and help inform shared decision making between clinicians and patients.

RESUMO

BACKGROUND: The current World Health Organization classification recognises 12 major subtypes of renal cell carcinoma (RCC). Although these subtypes differ on molecular and clinical levels, they are generally managed as the same disease, simply because they occur in the same organ. Specifically, there is a paucity of tools to risk-stratify patients with papillary RCC (PRCC). The purpose of this study was to develop and evaluate a tool to risk-stratify patients with clinically non-metastatic PRCC following curative surgery. METHODS: We studied clinicopathological variables and outcomes of 556 patients, who underwent full resection of sporadic, unilateral, non-metastatic (T1-4, N0-1, M0) PRCC at five institutions. Based on multivariable Fine-Gray competing risks regression models, we developed a prognostic scoring system to predict disease recurrence. This was further evaluated in the 150 PRCC patients recruited to the ASSURE trial. We compared the discrimination, calibration and decision-curve clinical net benefit against the Tumour, Node, Metastasis (TNM) stage group, University of California Integrated Staging System (UISS) and the 2018 Leibovich prognostic groups. RESULTS: We developed the VENUSS score from significant variables on multivariable analysis, which were the presence of VEnous tumour thrombus, NUclear grade, Size, T and N Stage. We created three risk groups based on the VENUSS score, with a 5-year cumulative incidence of recurrence equalling 2.9% in low-risk, 15.4% in intermediate-risk and 54.5% in high-risk patients. 91.7% of low-risk patients had oligometastatic recurrent disease, compared to 16.7% of intermediate-risk and 40.0% of high-risk patients. Discrimination, calibration and clinical net benefit from VENUSS appeared to be superior to UISS, TNM and Leibovich prognostic groups. CONCLUSIONS: We developed and tested a prognostic model for patients with clinically non-metastatic PRCC, which is based on routine pathological variables. This model may be superior to standard models and could be used for tailoring postoperative surveillance and defining inclusion for prospective adjuvant clinical trials.

RESUMO

OBJECTIVES: To report outcomes from a multiparametric (mp) magnetic resonance imaging (MRI)-based active surveillance programme that did not include performing protocol biopsies after the first confirmatory biopsy. PATIENTS AND METHODS: All patients diagnosed with Gleason 3 + 3 prostate cancer because of a raised PSA level who underwent mpMRI after diagnosis were included. Patients were recorded in a prospective clinical database and followed up with PSA monitoring and repeat MRI. In patients who remained on active surveillance after the first MRI (with or without confirmatory biopsy), we investigated PSA dynamics for association with subsequent progression. Comparison between first and second MRI scans was undertaken. Outcomes assessed were: progression to radical therapy at first MRI/confirmatory biopsy and progression to radical therapy in those who remained on active surveillance after first MRI. RESULTS: A total of 211 patients were included, with a median of 4.2 years of follow-up. The rate of progression to radical therapy was significantly greater at all stages among patients with visible lesions than in those with initially negative MRI (47/125 (37.6%) vs 11/86 (12.8%); odds ratio 4.1 (95% CI 2.0-8.5), P < 0.001). Only 1/56 patients (1.8%) with negative initial MRI scans who underwent a confirmatory systematic biopsy had upgrading to Gleason 3 + 4 disease. PSA velocity was significantly associated with subsequent progression in patients with negative initial MRI (area under the curve 0.85 [95% CI 0.75-0.94]; P <0.001). Patients with high-risk visible lesions on first MRI who remained on active surveillance had a high risk of subsequent progression 19/76 (25.0%) vs 9/84 (10.7%) for patients with no visible lesions, despite reassuring targeted and systematic confirmatory biopsies and regardless of PSA dynamics. CONCLUSION: Men with low-risk Gleason 3 + 3 prostate cancer on active surveillance can forgo protocol biopsies in favour of MRI and PSA monitoring with selective re-biopsy.

RESUMO

OBJECTIVES: To describe contemporary radical prostatectomy (RP) practice using the British Association of Urological Surgeons (BAUS) data and audit project and to observe differences in practice in relation to surgeon or centre case-volume. PATIENTS AND METHODS: Data on 13 920 RP procedures performed by 179 surgeons across 86 centres were recorded on the BAUS data and audit platform between 1 January 2014 and 31 December 2015. This equates to ~95% of total RPs performed over this period when compared to Hospital Episode Statistics (HES) data. Centre case-volumes were categorised as 'high' (>200), 'medium' (100-200) and 'low' (<100); surgeon case-volumes were categorised as 'high' (>100) and 'low' (<100). Differences in surgical practice and selected outcome measures were observed between groups. All data and volume categories were for the combined 2-year period. RESULTS: The median number of RPs performed over the 2-year period was 63.5 per surgeon and 164 per centre. Overall, surgical approach was robot-assisted laparoscopic RP (RALP) in 65%, laparoscopic RP (LRP) in 23%, and open RP (ORP) in 12%. The dominant approach in high-case-volume centres and by high-case-volume surgeons was RALP (74.3% and 69.2%, respectively). There was a greater percentage of ORPs reported by low-volume surgeons and centres when compared to higher volume equivalents. In all, 51.6% of all patients in this series underwent RP in high-case-volume centres using robot-assisted surgery (RAS). High-case-volume surgeons performed nerve-sparing (NS) procedures on 57.3% of their cases; low-volume surgeons performing NS on 48.2%. Overall, lymph node dissection (LND) rates were very similar across the groups. An 'extended' LND was more commonly performed in high-volume centres (22.1%). The median length of stay (LOS) was lowest in patients undergoing RALP at high-volume centres (1 day) and highest in ORP across all volume categories (3-4 days). Reported pT2 positive surgical margin (PSM) rate varied by technique, centre volume, and surgeon volume. In general, observed PSM rates were lower when RALP was the surgical approach (14.4%) and when high-volume surgeons were compared to low-volume surgeons (13.6% vs 17.7%). Transfusion rates were highest in ORP across all centres and surgeons (2.96-4.49%) compared to techniques using a minimally-invasive approach (0.25-2.41%). Training cases ranged from 0.5% in low-volume centres to 6.0% in high-volume centres. CONCLUSIONS: Compliance with data registration for centres and surgeons performing RP is high in the present series. Most RPs were performed in high-case-volume centres and by high-case-volume surgeons, with the most common approaches being minimally invasive and specifically RAS. High-case-volume centres and surgeons reported higher rates of extended LND and training cases. Higher-case-volume surgeons reported lower pT2 PSM rates, whilst the most marked differences in transfusion rates and LOS were seen when ORP was compared to minimally invasive approaches. Caution must be applied when interpreting these differences on the basis of this being registry data - causality cannot be assumed.

RESUMO

OBJECTIVES: To identify areas of agreement and disagreement in the implementation of multi-parametric magnetic resonance imaging (mpMRI) of the prostate in the diagnostic pathway. MATERIALS AND METHODS: Fifteen UK experts in prostate mpMRI and/or prostate cancer management across the UK (involving nine NHS centres to provide for geographical spread) participated in a consensus meeting following the Research and Development Corporation and University of California-Los Angeles (UCLA-RAND) Appropriateness Method, and were moderated by an independent chair. The experts considered 354 items pertaining to who can request an mpMRI, prostate mpMRI protocol, reporting guidelines, training, quality assurance (QA) and patient management based on mpMRI levels of suspicion for cancer. Each item was rated for agreement on a 9-point scale. A panel median score of ≥7 constituted 'agreement' for an item; for an item to reach 'consensus', a panel majority scoring was required. RESULTS: Consensus was reached on 59% of items (208/354); these were used to provide recommendations for the implementation of prostate mpMRI in the UK. Key findings include prostate mpMRI requests should be made in consultation with the urological team; mpMRI scanners should undergo QA checks to guarantee consistently high diagnostic quality scans; scans should only be reported by trained and experienced radiologists to ensure that men with unsuspicious prostate mpMRI might consider avoiding an immediate biopsy. CONCLUSIONS: Our consensus statements demonstrate a set of criteria that are required for the practical dissemination of consistently high-quality prostate mpMRI as a diagnostic test before biopsy in men at risk.

RESUMO

INTRODUCTION: Surgery for prostate cancer can result in distressing side effects such as sexual difficulties, which are associated with lower levels of dyadic functioning. The study developed and tested an intervention to address sexual, relational, and emotional aspects of the relationship after prostate cancer by incorporating elements of family systems theory and sex therapy. AIMS: To develop and test the feasibility and acceptability of relational psychosexual treatment for couples with prostate cancer, determine whether a relational-psychosexual intervention is feasible and acceptable for couples affected by prostate cancer, and determine the parameters for a full-scale trial. METHODS: Forty-three couples were recruited for this pilot randomized controlled trial and received a six-session manual-based psychosexual intervention or usual care. Outcomes were measured before, after, and 6 months after the intervention. Acceptability and feasibility were established from recruitment and retention rates and adherence to the manual. MAIN OUTCOME MEASURES: The primary outcome measurement was the sexual bother subdomain of the Expanded Prostate Cancer Index Composite. The Hospital Anxiety and Depression Scale and the 15-item Systemic Clinical Outcome and Routine Evaluation (SCORE-15) were used to measure emotional and relational functioning, respectively. RESULTS: The intervention was feasible and acceptable. The trial achieved adequate recruitment (38%) and retention (74%) rates. The intervention had a clinically and statistically significant effect on sexual bother immediately after the intervention. Small decreases in anxiety and depression were observed for the intervention couples, although these were not statistically significant. Practitioners reported high levels of adherence to the manual. CONCLUSION: The clinically significant impact on sexual bother and positive feedback on the study's feasibility and acceptability indicate that the intervention should be tested in a multicenter trial. The SCORE-15 lacked specificity for this intervention, and future trials would benefit from a couple-focused measurement.

RESUMO

To systematically review the range of methods available for assessing elasticity in the prostate and to examine its use as a biomarker for prostate cancer. A systematic review of the electronic database PubMed was performed up to December 2012. All relevant studies assessing the use of elasticity as a biomarker for prostate cancer were included except those not studying human prostates or reporting a sensitivity, specificity or quantitative elasticity value. There has been much interest in the use of elasticity in the detection of prostate cancer and there have been many publications using various methods of detection. The most common method of assessment is an imaging method, called sonoelastography. Further imaging methods include ultrasound (US), three-dimensional US and magnetic resonance elastography. These methods are reviewed for sensitivity and specificity. The other method of assessment is the mechanical method. These use quantitative elasticity values to differentiate benign from malignant areas of the prostate. This method of assessment has shown that the elasticity changes for differing Gleason grades and T stages of disease within the prostate. Quantitative elasticity values offer the potential of using 'threshold' elasticity values under which the prostate is benign. Tissue elasticity has great potential as a diagnostic and prognostic biomarker for prostate cancer and can be assessed using various methods. Currently transrectal sonoelastography has the most evidence supporting its use in clinical practice.

RESUMO

OBJECTIVE: Does decision navigation (DN) increase prostate cancer patients' confidence and certainty in treatment decisions, while reducing regret associated with the decisions made? METHODS: Two hundred eighty-nine newly diagnosed prostate cancer patients were eligible. 123 consented and were randomised to usual care (n = 60) or navigation (n = 63). The intervention involved a 'navigator' guiding the patient in creating a personal question list for a consultation and providing a CD and typed summary of the consultation to patients, the general practitioner and physician. The primary outcome was decisional self efficacy. Secondary outcomes included decisional conflict (DCS) and decisional regret (RS). Measures of mood (Hospital Anxiety and Depression Scale) and adjustment (Mental Adjustment to Cancer Scale) were included to detect potential adverse effects of the intervention. RESULTS: ANOVA showed a main effect for the group (F = 7.161, df 1, p = 0.009). Post hoc comparisons showed significantly higher decisional self efficacy in the navigated patients post-consultation and 6 months later. Decisional conflict was lower for navigated patients initially (t = 2.005, df = 105, p = 0.047), not at follow-up (t = 1.969, df = 109, p = 0.052). Regret scores were significantly lower in the navigation group compared to the controls 6 months later (t = -2.130, df = 100, p = 0.036). There was no impact of the intervention on mood or adjustment. CONCLUSION: Compared to control patients, navigated patients were more confident in making decisions about cancer treatment, were more certain they had made the right decision after the consultation and had less regret about their decision 6 months later. Decision navigation was feasible, acceptable and effective for newly diagnosed prostate cancer patients in Scotland.

RESUMO

OBJECTIVES: Urologists are cautious to offer minimally invasive radical prostatectomy in prostate cancer patients with high prostate-specific antigen (and therefore anticipated to have locally advanced or metastatic disease) because of concerns regarding lack of complete cure after minimally invasive radical prostatectomy and of worsening of continence if adjuvant radiotherapy is used. METHODS: A retrospective review of our institutional database was carried out to identify patients with PSA ≥20 ng/mL who underwent minimally invasive radical prostatectomy between January 2002 and October 2010. Intraoperative, pathological, functional and short-term oncological outcomes were assessed. RESULTS: Overall, 233 patients met study criteria and were included in the analysis. The median prostate-specific antigen and prostate size were 28.5 ng/mL and 47 mL, respectively. Intraoperative complications were the following: rectal injury (0.86%) and blood transfusion (1.7%). Early postoperative complications included prolonged (>6 days) catheterization (9.4%), hematoma (4.7%), deep venous thrombosis (0.86%) and lymphocele (5.1%). Late postoperative complications included cerebrovascular accident (0.4%) and anastomotic stricture (0.8%). Pathology revealed poorly differentiated cancer in 48.9%, pT3/pT4 disease in 55.8%, positive margins in 28.3% and lymph node disease in 20.2% of the cases. Adverse pathological findings were more frequent in patients with prostate-specific antigen >40 ng/mL and (or) in those with locally advanced disease (pT3/pT4). In 62.2% of the cases, adjuvant radiotherapy was used. At 1-year follow up, 80% of patients did not show evidence of biochemical recurrence and 98.8% of them had good recovery of continence. CONCLUSION: Minimally invasive radical prostatectomy might represent a reasonable option in prostate cancer patients with high prostate-specific antigen as a part of a multimodality treatment approach.

RESUMO

PURPOSE: To determine the optimal post-operative risk stratification system associated with survival following surgery for clear cell renal cell carcinoma (ccRCC): tumour grade, tumour stage, Leibovich 2003, Leibovich 2018, Kattan, Stage, size, grade and necrosis (SSIGN) or UCLA Integrated Staging System (UISS) scores. METHODS: 542 patients with non-metastatic ccRCC who underwent nephrectomy 2008-2018 were reviewed. Primary outcome was recurrence-free survival (RFS), with secondary outcomes cancer-specific survival (CSS) and overall survival (OS). RESULTS: All systems were significantly associated with RFS, CSS and OS by Kaplan-Meier and unadjusted Cox-regression. ROC analysis identified that Leibovich 2003, Leibovich 2018A or B and SSIGN were optimally association with 5year RFS (AUC (Area under curve) 0.87, 0.86, 0.86 and 0.86), but Leibovich 2003 or 2018A offered additional information on adjusted regression analysis (HR 1.24, P = 0.02; HR 1.17, P = 0.04). ROC analysis identified that Leibovich 2018B, Leibovich 2003, SSIGN and UISS were equally associated with 5 year OS (AUC 0.76, 0.74, 0.73 and 0.72). UISS added additional explanation of the variance in OS on adjusted regression analysis (HR 1.96, P = 0.002). A novel combination of Leibovich 2003 score and Eastern Co-operative Oncology Group (ECOG) performance status improved 5 year OS association compared to the Leibovich 2003 alone (AUC 0.78, P = 0.001), without affecting association with 5year RFS (AUC 0.87, P = 0.75). CONCLUSIONS: All systems were robust tools associated with RFS, CSS and OS in ccRCC. In our cohort, the Leibovich 2003 and Leibovich 2018A scores may be better associated with RFS compared to other strategies. The UISS, Leibovich 2018B or Leibovich 2003 combined with ECOG performance status may stratify OS better than other modalities.

RESUMO

OBJECTIVE: To assess the outcomes and learning curve of extraperitoneal endoscopic radical prostatectomy (EERP) using cumulative summation charts from a single tertiary referral centre. PATIENTS AND METHODS: The data from 300 consecutive men with localized prostate cancer who underwent EERP at Western General Hospital, Edinburgh, UK, between February 2006 and July 2009 were prospectively maintained in a database. The data collected included demographic details, perioperative outcomes, complications and follow-up for functional and oncology outcomes. The learning curve was analysed using generalized linear models for complication rate, operative time and blood loss, using procedure experience. RESULTS: The mean (sd, range) operative duration was 160.52 (40.84, 100-310) min, and the intraoperative blood loss was 229.3 (172, 20-1000) mL. There was no conversion to open surgery and no patient required intraoperative blood transfusion. Only one of 250 (0.3%) patients required a blood transfusion after EERP. The median (range) hospital stay was 3 (2-20) days and the median catheterization time before cystography was 9 days. There was evidence that the complication rate reduced as experience was gained (odds ratio 0.98, 95% confidence interval, CI, 0.97-0.99; P= 0.002), with the estimated probability of a complication decreasing from 29% for the first to <1% for the 250th procedure. Also there was evidence of a decrease in operative duration (-0.0020 rate parameter on log scale; 95% CI -0.0024 to -0.0017; P < 0.001) and blood loss (-0.01 rate parameter on log scale; 95% CI -0.003 to -0.0002; P= 0.021). The positive surgical margin rate in pT2 disease decreased from 27% in the first 50 to 14.7% in the last 50 operated cases. The continence rate and biochemical recurrence-free rate at a minimum follow-up of 1 year for the first 100 patients was 89% and 94%, respectively. CONCLUSION: The results from this series suggest that the benefits of minimally invasive surgery for localized prostate cancer (EERP) can be replicated after mentored fellowship training of a surgeon. The complication rate reduced substantially as experience was gained, suggesting a continuous surgical learning curve.

RESUMO

OBJECTIVES: Our purpose was to review current practice regarding the use of prostate biopsies in men older than 75 years with raised PSA by presenting the results of a retrospective audit and to identify these older men who really benefit from prostate biopsies. METHODS: A high-volume tertiary center's prospectively maintained prostate biopsy database of contemporary biopsies was reviewed. Men were stratified by age and PSA. Logistic regression analysis, Mantel-Haenszel and Fisher's exact tests were used for statistical analysis. RESULTS: Overall, 1,593 men underwent prostate biopsies between April 2004 and August 2006. Of these, 293 patients (18.4%) with a mean age of 82.62 years and mean PSA of 30.37 ng/ml were eligible for the study with an overall incidence of prostate cancer of 73.7%. Elderly men with PSA >20 ng/ml had a prostate cancer detection rate of 91%. They were more likely to have-high grade disease (OR = 5.4, 95% CI = 2.8-10.8, p < 0.0001) and receive hormone deprivation therapy (RR = 3.0, 95% CI = 2.1-4.3, p < 0.0001). Elderly men with PSA <20 ng/ml had a 3-fold risk of being placed on active monitoring. Almost 20% of them had 1 complication following biopsy, of whom 12 (4.1%) needed hospitalization. CONCLUSIONS: Given the high probability of detecting prostate cancer and receiving conservative treatment, prostate biopsies can be omitted in men >75 years with PSA >20 ng/ml. However, they are still useful in fit men >75 and <80 years with PSA <20 ng/ml who can be the potential candidates for treatment with curative intent.

RESUMO

Identification and characterization of nodules in soft tissue, including their size, shape, and location, provide a basis for tumor identification. This study proposes an inverse finite-element (FE) based computational framework, for characterizing the size of examined tissue sample and detecting the presence of embedded tumor nodules using instrumented palpation, without a priori anatomical knowledge. The inverse analysis was applied to a model system, the human prostate, and was based on the reaction forces which can be obtained by trans-rectal mechanical probing and those from an equivalent FE model, which was optimized iteratively, by minimizing an error function between the two cases, toward the target solution. The tumor nodule can be identified through its influence on the stress state of the prostate. The effectiveness of the proposed method was further verified using a realistic prostate model reconstructed from magnetic resonance (MR) images. The results show the proposed framework to be capable of characterizing the key geometrical indices of the prostate and identifying the presence of cancerous nodules. Therefore, it has potential, when combined with instrumented palpation, for primary diagnosis of prostate cancer, and, potentially, solid tumors in other types of soft tissue.

RESUMO

Abdominal aortic aneurysm (AAA) rupture commonly presents with abdominal or lower back pain and haemodynamic instability. There have been case reports of co-existing left testicular pain;(1) however, very few cases describe right testicular pain as the sentinel symptom. We discuss the case of a 75-year-old man who presented to the on-call urologists with a 6-day history of right testicular pain. On examination, a painless AAA was detected. The patient was stable and a CT scan demonstrated a large AAA extending into the right iliac vessels, with suggestion of leakage. Attempted emergency repair was unsuccessful and the patient died in theatre. This atypical presentation of occult aneurysm leak highlights the need for clinical vigilance in the older patient with seemingly benign groin symptoms, including isolated right testicular pain.

RESUMO

INTRODUCTION: In our series of 1,900 endoscopic extraperitoneal radical prostatectomies (EERPE) the incidence of symptomatic lymphocele following simultaneous pelvic lymph node dissection (PLND) is between 3 and 14% depending on the extent of lymph node dissection. We report the impact of bilateral peritoneal fenestration after completion of extraperitoneal prostatectomy and PLND on the incidence of lymphocele, postoperative pain and complications. PATIENTS AND METHODS: A total of 100 consecutive patients undergoing EERPE and extended PLND were allocated into two groups. In Group A (n = 50) a 4-6 cm incision was performed bilaterally over the external iliac vessels down to the obturator fossa after completion of the main procedure. In Group B (n = 50) no peritoneal incisions were made. The postoperative assessment protocol included a visual analogue pain scale administered three times daily for 6 days, analgesia requirement, and ultrasound examination on 4th and 8th days, and 3 months postoperatively. CRP and leucocyte counts were measured on 1st and 2nd postoperative days. Complications were recorded according to our standard protocol using the Clavien classification. RESULTS: Three patients (6%) in Group A were found to have lymphoceles, none of which were symptomatic. Significantly more patients in Group B developed a lymphocele, (n = 16, 32%, P < 0.001) of which a significant number were symptomatic (n = 7, 14%, P < 0.001) and required laparoscopic fenestration. No significant difference was observed between the pain score in either group. Mean pain scores were 3.4 versus 3.8 at 6 h, and 0.8 versus 1.1 at 6 days, respectively. No difference in analgesia requirement, serum inflammatory markers and return to normal bowel activity was observed between the groups. CONCLUSIONS: This study demonstrates that peritoneal fenestration significantly reduces the incidence of both symptomatic and asymptomatic lymphocele, without an increase in postoperative morbidity. As symptomatic lymphocele is one of the most common complications of extraperitoneal PLND requiring reintervention, we recommend that peritoneal fenestration should be performed routinely after extraperitoneal radical prostatectomy and PLND.

RESUMO

PURPOSE: Trial without catheter after a short course of an alpha-blocker in men presenting with acute urinary retention is successful in up to 50% of cases. The ability to better predict outcome could avoid a trial without catheter for some men. Intravesical prostatic protrusion and not prostate volume has been shown to predict trial without catheter outcome in an Asian cohort. We investigated the relationship between the outcome of trial without catheter and prostate volume and intravesical prostatic protrusion in white men given alpha-blockers before a trial without catheter. MATERIALS AND METHODS: Consecutive men 50 years old or older presenting with acute urinary retention were prospectively recruited based on strict selection criteria. At presentation factors thought to precipitate acute urinary retention were treated, alpha-blocker therapy started and the patient brought back for a trial without catheter after 2 weeks. Prostate volume and intravesical prostatic protrusion were measured by standard transrectal ultrasonography. RESULTS: Of 121 men presenting with acute urinary retention 57 fulfilled the study selection criteria. Mean (+/- SD) age, prostate volume and intravesical prostatic protrusion of recruited men were 70 +/- 9.2 years, 69.7 +/- 36.3 ml and 12.8 +/- 10.1 mm, respectively. A total of 25 men (43.9%) had a successful trial without catheter. Mean intravesical prostatic protrusion was significantly smaller in those who had a successful trial without catheter (7.2 vs 16.5 mm, 95% CI 4.5-14, p <0.001). With intravesical prostatic protrusion correlating well with prostate volume (r = 0.588), mean prostate volume was also smaller in men with a successful trial without catheter, albeit with a smaller effect size. Men with an intravesical prostatic protrusion of 10 mm or less, compared to those with a larger intravesical prostatic protrusion, were 6 times more likely to have a successful trial without catheter. CONCLUSIONS: In this cohort presenting with acute urinary retention related to benign prostatic hyperplasia and receiving alpha-blockers before a trial without catheter, intravesical prostatic protrusion appears to strongly predict the outcome of a trial without catheter. A trial without catheter is more likely to fail in patients with intravesical prostatic protrusion larger than 10 mm.
