RESUMEN
We investigated whether prostate cancer patients treated with external beam radiation therapy (EBRT) have a higher cumulative incidence of secondary cancer compared with patients treated with radical prostatectomy (RP). We used state-wide linked data from South Australia to follow men with prostate cancer diagnosed from 2002 to 2019. The cumulative incidence of overall and site-specific secondary cancers between 5 and 15 years after treatment was estimated. Fine-Gray competing risk analyses were performed with additional sensitivity analyses to test different scenarios. A total of 7625 patients were included (54% underwent RP and 46% EBRT). Characteristics of the two groups differed significantly, with the EBRT group being older (71 vs. 64 years), having higher comorbidity burden and being more likely to die during follow-up than the RP group. Fifteen-year cumulative incidence for all secondary cancers was 27.4% and 22.3% in EBRT and RP groups, respectively. In the adjusted models, patients in the EBRT group had a significantly higher risk of genitourinary (adjusted subhazard ratio (aSHR), 2.29; 95%CI 1.16-4.51) and lung (aSHR, 1.93; 95%CI 1.05-3.56) cancers compared with patients in the RP group. However, there was no statistically significant difference between the two groups for risk of any secondary cancer, gastro-intestinal, skin or haematologic cancers. No statistically significant differences in overall risk of secondary cancer were observed in any of the sensitivity analyses and patterns for risk at specific cancer sites were relatively consistent across different age restriction and latency/time-lag scenarios. In conclusion, the increased risk of genitourinary and lung cancers among men undergoing EBRT may relate partly to treatment effects and partly to unmeasured residual confounding.

BACKGROUND: Recent studies have shown that radiation-induced pelvic toxicity often requires urological consultation. However, the 10-year incidence of genitourinary toxicity following intensity-modulated radiotherapy (IMRT) amongst patients with localised prostate cancer remains unclear. Hence, we conducted a systematic review and meta-analysis to determine the incidence of late genitourinary toxicity relying on Radiation Therapy Oncology Group (RTOG) and Common Terminology Criteria for Adverse Events (CTCAE) grade as well as the incidence of specific genitourinary toxicity. Secondary objectives involved quantifing the number of studies reporting 120-month follow-up endpoints, time to event analysis, predictive factors or economic evaluation. METHODS: Articles published from January 2008 to December 2021 describing prospective studies were systematically searched in MEDLINE, EMBASE and Cochrane (PROSPERO protocol CRD42019133320). Quality assessment was performed by use of the Cochrane Risk of Bias 2 Tool for RCTs and the Newcastle Ottowa Scale for non-RCTs. Meta-analysis was performed on the 60-month incidence of RTOG and CTCAE Grade ≥2 genitourinary toxicity, haematuria, urinary retention and urinary incontinence. RESULTS: We screened 4721 studies and six studies met our inclusion criteria. All included studies involved normofractionation, three included a hypofractionation comparator arm and none involved nodal irradiation. The pooled 60-month cumulative incidence of RTOG and CTCAE Grade ≥2 genitourinary toxicity were 17% (95% CI: 5-20%, n = 678) and 33% (95% CI: 27-38%, n = 153), respectively. The pooled 60-month cumulative incidence of Haematuria was 5% (95% CI: -4-14%, n = 48), Urinary incontinence 12% (95% CI: 6-18%, n = 194), Urinary retention 24% (95% CI: 9-40%, n = 10). One study reported time to event analyses, one reported predictive factors, no studies reported economic analysis or 120-month toxicity. There was considerable heterogeneity amongst the studies. CONCLUSION: There are few high-quality studies reporting 60-month toxicity rates after IMRT. Conservative estimates of 60-month toxicity rates are high and there is need for longer follow-up and consistent toxicity reporting standards.

PURPOSE: The risk of treatment-related toxicity is important for patients with localised prostate cancer to consider when deciding between treatment options. We developed a model to predict hospitalisation for radiation-induced genitourinary toxicity based on patient characteristics. METHODS: The prospective South Australian Prostate Cancer Clinical Outcomes registry was used to identify men with localised prostate cancer who underwent curative intent external beam radiotherapy (EBRT) between 1998 and 2019. Multivariable Cox proportional regression was performed. Model discrimination, calibration, internal validation and utility were assessed using C-statistics and area under ROC, calibration plots, bootstrapping, and decision curve analysis, respectively. RESULTS: There were 3,243 patients treated with EBRT included, of which 644 (20%) patients had a treated-related admission. In multivariable analysis, diabetes (HR 1.35, 95% CI 1.13-1.60, p < 0.001), smoking (HR 1.78, 95% CI 1.40-2.12, p < 0.001), and bladder outlet obstruction (BOO) without transurethral resection of prostate (TURP) (HR 7.49, 95% CI 6.18-9.08 p < 0.001) followed by BOO with TURP (HR 4.96, 95% CI 4.10-5.99 p < 0.001) were strong independent predictors of hospitalisation (censor-adjusted c-statistic = 0.80). The model was well-calibrated (AUC = 0.76). The global proportional hazards were met. In internal validation through bootstrapping, the model was reasonably discriminate at five (AUC 0.75) years after radiotherapy. CONCLUSIONS: This is the first study to develop a predictive model for genitourinary toxicity requiring hospitalisation amongst men with prostate cancer treated with EBRT. Patients with localised prostate cancer and concurrent BOO may benefit from TURP before EBRT.

Pelvic radiation is increasingly being used for the neoadjuvant and definitive treatment of pelvic organ malignancy. While this treatment can be highly effective, and may assist in organ sparing, it is also associated with significant toxicity and devastating adverse events that need to be considered. In broad terms, pelvic radiation disease affects both the primary target organ as well as adjacent organs and soft tissue structures, with complications that can be classified and graded according to consensus criteria. The complication grade is often modality, dose, and area dependent. The most common manifestations are proctitis, cystitis, recto-urethral fistula, ureteric stricture, and bone involvement. Toxicity can be misdiagnosed for many years, resulting in significant management delays. Complications can be difficult to prevent and challenging to treat, requiring specialized multi-disciplinary input to achieve the best possible strategy to minimize impact and improve patient quality of life.
RESUMEN
PURPOSE: Studies of genitourinary toxicity following radiotherapy for prostate cancer are mainly from high volume single institutions and the incidence and burden of treatment remain uncertain. Hence we determine the cumulative incidence of treatment-related genitourinary toxicity in patients with localised prostate cancer treated with primary external beam radiotherapy (EBRT) at a state population level. METHODS: We analysed data from a prospective population-based cohort, including hospital admission and cancer registry data, for men with localised prostate cancer who underwent primary EBRT without nodal irradiation between 1998 and 2019 in South Australia. The 10-year cumulative incidence of genitourinary toxicity requiring hospitalisation or procedures was determined. Clinical predictors of toxicity and the volume of admissions, non-operative, minor operative and major operative procedures were determined. RESULTS: All the included patients (n = 3350) had EBRT, with a median (IQR) of 74 Gy (70-78) in 37 fractions (35-39). The 10-year cumulative incidence of was 28.4% (95% CI 26.3-30.6) with a total of 2545 hospital admissions, including 1040 (41%) emergency and 1893 (74%) readmissions. The 10-year cumulative incidence of patients in this cohort requiring a urological operative procedure was 18% (95% CI 16.1-19.9), with a total of 106 (4.2%) non-operative, 1044 (41%) minor operative and 57 (2.2%) major operative urological procedures. CONCLUSIONS: Genitourinary toxicity after radiotherapy for prostate cancer is common. Although there continue to be advancements in radiotherapy techniques, patients and physicians should be aware of the risk of late toxicity when considering EBRT.

INTRODUCTION AND OBJECTIVES: Urodynamic studies are often performed in the evaluation of post-prostatectomy urinary incontinence (PPUI). The male transobturator sling (TOS) is a minimally invasive treatment for PPUI. Others have reported their results with a specific Valsalva leak point pressure (VLPP) that predicts a good outcome with the male TOS. Our objective was to determine the relationship of the pre-operative VLPP on the success rate of the male TOS in a high-volume, single center. We hypothesized that a higher pre-operative VLPP better predicts successful outcomes. METHODS: We reviewed patients undergoing a male TOS placement from 2006 to 2012 at our institution. Patients who underwent TOS placement were identified using our patient data portal (DEDUCE). Demographic, urodynamic, and follow-up data were extracted by chart review. Post-operative success was defined by the use of 0 or 1 security pad, a negative stress test on exam, or pad weight of less than 8 g per 24 h. Cox and linear regression models were performed. RESULTS: 290 patients were included. All patients underwent a radical prostatectomy for prostate cancer and presented with PPUI. Mean age at surgery was 66.3 (± 7.4) years and 84% were Caucasian. Median time to follow-up was 5 months (IQR 1-15). A linear regression model shows an inverse prediction curve for sling failure versus VLPP (p = 0.02). The hazard ratio for failure with a VLPP of ≤ 70 cm H2O compared with a VLPP of > 70 cm H2O, adjusted for pelvic radiation and 24-h pad weight was 0.5 (95% CI 0.2-0.98). CONCLUSION: Patient selection is imperative in the success of the male TOS for patients with PPUI. In our cohort of patients with PPUI, those with a pre-procedural VLPP of > 70 cm H2O were 50% less likely to fail after TOS placement versus those with a VLPP ≤ 70 cm H2O. In our practice, we use these data to support the use of VLPP cut off of 70 cm H2O as an indicator for success to help in the evaluation and counseling of patients.

BACKGROUND: Recent evidence from observational studies suggests a bidirectional association between lower urinary tract symptoms (LUTS) and depression in men. We sought to systematically quantify the effect of the presence of LUTS on depression symptoms, compared to those without LUTS, in adult males, and vice versa. METHODS: Electronic databases (MEDLINE, PsycINFO, SCOPUS, Embase) were examined for articles in English before March 2021. Observational studies of men aged over 18 years; reporting an association between LUTS and depression; including a validated scale for LUTS and depression symptoms were eligible for study inclusion. RESULTS: Seventeen studies out of 1787 records identified 163 466 men with reported depression symptoms by LUTS status, while 10 studies reported 72 363 men with LUTS by depression symptoms. Pooled estimates showed a strong effect of LUTS presence on depression risk (OR: 2.89, 95% CI: 2.50-3.33), with a high degree of heterogeneity among the examined studies (I2 = 83%; τ2 = 0,06; p < 0.001). Subgroup analyses demonstrated differences by study region (Q value:13.7, df:4, p = 0.003), setting (7.8(2), p = 0.020), design (7.2(1), p = 0.003), quality (6.2(1), p = 0.013), and LUTS measure (40.9(3), p < 0.001). Pooled estimates also showed a strong effect of depression presence on LUTS risk in men (OR: 3.13, 95% CI: 2.72-3.60), with only moderate heterogeneity between studies (I2 = 58%; τ2 = 0,02; p = 0.001). CONCLUSIONS: The strong relationship observed between LUTS and depression implies shared risk factors that cannot be solely attributed to the prostate. This has immediate implications for future studies and the assessment and management of patients with either condition.

OBJECTIVE: To investigate the changes in elective private urological procedures in Australia during the coronavirus disease 2019 pandemic. METHODS: Data were extracted from publicly available datasets from Medicare Benefits Schedule using item numbers assigned to each commonly performed urological intervention. These procedures were divided into three groups: Oncological therapeutic, diagnostic, and non-oncological therapeutic procedures. A smoothing model, based on the historic procedure numbers from 2017 to 2019, was used to forecast monthly number of procedures performed in each category between January 2020 and June 2020. These forecasted models were compared with reported figures. RESULTS: A total of 108 169 procedures were performed between January 2020 and June 2020 based on the Medicare Benefits Schedule item numbers listed. There was a significant reduction (percentage change) in total procedures performed in April 2020 (-22.6%, 95% confidence interval [CI]: -28.7% to -15.4%) and May 2020 (-33.2%, 95% CI: -37.5% to -28.3%). There was a significant reduction in oncological therapeutic, non-oncological therapeutic, and diagnostic procedures performed in April 2020 and May 2020 (p<0.05). These numbers did not include procedures performed in public sector. CONCLUSION: There was a significant reduction in total urological procedures (including diagnostic, oncological, and non-oncological) performed in months of April 2020 and May 2020 during time of federal restrictions. Both public and private healthcare sectors need to be supported in the upcoming months to prevent further delays in treatment and poorer clinical outcomes.
RESUMEN
BACKGROUND: Recent studies of patients with Fournier's gangrene (FG) highlight the importance of early surgical intervention in improving mortality rates. We prospectively determined subgroups of patients with FG at high risk of severe local morbidity. METHODS: We prospectively evaluated all patients diagnosed with FG at a tertiary hospital (1 January 2018 to 1 January 2021). Data were collated on demographics, comorbidity, infection source, treatment and clinical outcomes. RESULTS: We identified 14 consecutive male patients with a median (interquartile range) age of 57 (50-64) years. Most common risk factors were diabetes (n = 10, 71%) and obesity (n = 10, 71%). Median (range) HbA1c was 11.20 (7.5-15.3), and body mass index of 41.25 (23.7-70.0). Seven patients had adjacent organ involvement (AOI), involving the corporal bodies (57%) and testes (43%). The most common suspected source was dermatological (50%), followed by genitourinary (29%) and gastrointestinal (GI) (21%). Median (interquartile range) hospital length of stay (LOS) was 32 (8.5-30.75) days. Patients with AOI were more likely to have a suspected GI source, need mechanical ventilation (p = 0.023), a significantly longer LOS (p = 0.015) and time to wound closure (p = 0.04). Patients with suspected dermatological origin of infection, had a significantly lower rate of AOI (p = 0.029), mechanical ventilation (p = 0.029) and a shorter LOS (p = 0.035). CONCLUSION: In our prospective series, FG is associated with a high rate of AOI and suspected non-dermatological origin of infection, which confers significant perioperative morbidity including the need for mechanical ventilation, LOS and longer time from initial debridement to wound closure.

INTRODUCTION: Tri-tubular penile fracture is a very rare subset of penile fractures, typically due to high-energy trauma to the erect penis. CASE PRESENTATION: A 26-year-old healthy man presents with a triad of audible crack, immediate detumescence, and hematoma formation, following blunt trauma sustained during vaginal sexual intercourse. A diagnosis of penile fracture is made, with intraoperative finding of a complete traumatic transection of the urethra with total bilateral corpus cavernosa disruption. Both corpora cavernosa were repaired using 2/0 polydioxanone sutures, with the dartos fascia placed in between. The urethra was repaired with interrupted 5/0 polyglactin braided absorbable suture. At 5 weeks, patient reported normal erections and sexual activity with no physical or psychological issues. The literature on management was reviewed. CONCLUSION: Current evidence of surgical management of tri-tubular penile fractures remains predominantly expert opinion, due to difficulties of conducting prospective trials for a rare condition.
RESUMEN
OBJECTIVE: To identify and explore the various classification systems that have been proposed for anterior urethral stricture disease (AUSD) and to identify the advantages and disadvantages of each. METHODS: A comprehensive systematic review was conducted in MEDLINE, EMBASE, SCOPUS and COCHRANE databases with a search strategy created appropriately. Titles and abstracts of search results were screened by two authors and selected for full-text review. Studies exploring urethral stricture classification, clinical scoring or staging systems used in men over the age of 18 with benign anterior urethral stricture disease were included. RESULTS: The search identified 3113 articles, of which 10 were selected for inclusion after scrutiny. Four classification systems were identified. These include ULTRA score, urethral stricture score, cystoscopy-based staging system and Gombe Urethrographic score. These were based on various modalities, including cystoscopy, retrograde urethrogram (RUG) and sonourethrogram (SUG). From the scoring systems identified, the urethral stricture scoring system has multiple external validation studies and is predictive of operative complexity, operative time, recurrence and postoperative complications. CONCLUSIONS: Several classification systems have been proposed for AUSD. Each has its advantages and disadvantages. The urethral stricture score has been externally validated and shown to been predictive of surgical outcomes and recurrence. There are no scores that incorporate patient-related outcome measures (PROMs). Many classification systems have yet to provide sufficient external validation. Further external validation studies are needed before the general adoption of a particular system.

OBJECTIVE: To assess the histologic findings in the pubic bone resected during extirpative surgery for urinary pubic symphysis fistula (UPF). The concurrent presence of osteomyelitis and the need for bone resection at time of extirpative surgery for UPF has been debated. We hypothesized that UPF results in histopathologically confirmed osteomyelitis, underscoring the importance of bone resection at the time of surgery. METHODS: An IRB-approved retrospective review of all patients undergoing surgery for UPF from 2012 to 2019 was performed. Demographic data were recorded. A single pathologist performed histopathologic examination of bone tissue in each case. Logistic regression and Fisher exact test were used to assess association of osteomyelitis with clinical factors. RESULTS: We identified 36 patients who underwent major extirpative surgery for UPF with bone pathology available for review. Bone histopathology findings confirmed presence of osteomyelitis in the majority (nâ¯=â¯32, 88.9%). This was characterized as chronic osteomyelitis in 15 (41.7%), acute osteomyelitis only in 1 (2.8%) and combined chronic, and acute osteomyelitis in 16 (44.4%). Osteonecrosis was seen in 11 cases (33.6%). There was no correlation between presence of osteomyelitis and age, timing from radiotherapy to diagnosis of UPF, type of radiotherapy, or history of endoscopic bladder outlet procedures. CONCLUSION: Osteomyelitis is present on histology of the pubic bone resected during surgery for UPF in the majority of cases (88.9%). Osteonecrosis is also common. These findings underscore the critical importance of pubic bone resection at time of UPF surgery to adequately treat the diseased bone.

OBJECTIVE: To review the published literature evaluating the efficacy and safety of buccal mucosa ureteroplasty. METHODS: A systematic literature review was carried out using a protocol devised a priori. The review was registered with the Joanna Briggs Institute. Results were scrutinized and full text of all relevant articles was obtained for review. RESULTS: A systematic search resulted in 1092 articles, with scrutiny resulting in 1079 exclusions. Two additional articles were identified from references, resulting in a total of 15 included studies containing a total of 72 buccal mucosal ureteroplasty procedures. A total of 34 cases were carried out using the open approach, and 38 were carried out using the robot assisted approach. The overall reported success rate was reported to be 66 out of 72 (91.6%), being 32 out of 34 (94.1%) and 34 out of 38 (89.5%) open and robotic cases, respectively. The complication rate was reported in 60 cases, being 15 out of 60 (25%) for all complications, with a 5% (3/60) rate for complications graded as Clavien-Dindo score ≥3. CONCLUSIONS: Buccal mucosa ureteroplasty appears to have high success rates and low rates of serious complications in both open and robot assisted approaches. However, the current available literature is limited to 72 cases, and further studies with larger patient populations and ongoing longitudinal review are warranted.

BACKGROUND: Anecdotal evidence reveals that medical equipment are easily found in hospital changing rooms. Access to potentially lethal drugs and intravenous access equipment may put vulnerable medical staff at risk. The aims are to quantify the burden of medical equipment found in this environment, calculate the associated cost burden and to raise clinician awareness about a potential health hazard. METHODS: We prospectively collected data on the medical paraphernalia found in surgical changing rooms from one private and two public hospitals in South Australia over 2 months. We systematically searched open surgical lockers, benches and floors in male and female lockers rooms. Item costs were calculated from Imprest and the Pharmacy Department. RESULTS: During the study period, we found a total of 537 items. There were 280 sharps, including 185 scalpels found in one open locker. There were 78 items of intravenous paraphernalia, 38 surgical tapes, 70 bandages and 73 miscellaneous items. In addition, there were six medications found including 3 × 5 mL vials of 1% lignocaine, one vial of lignocaine with adrenaline, one ketorolac suppository and 5 mL fentanyl. There were 529 (98.5%) items within their date of expiry. The total cost of the items was 2358 Australian dollars (AUD), with an estimated annual cost of 14 148 AUD over the three sites and 424 400 AUD over South Australia. CONCLUSION: The burden of available medical supplies found in the theatre changing room is high and worrisome. Strategies for appropriate disposal and safe storage of medical equipment are required.

OBJECTIVE: To examine the infectious features of patients with urinary pubic symphysis fistula (UPF) and their association with osteomyelitis. METHODS: We conducted a review of our quality improvement database for 36 patients with UPF undergoing bone resection and extirpative surgery from October 2012 to January 2019. An assessment of bone and urine cultures was carried out along with surgical, radiologic, and demographic data. We analyzed descriptive statistics and used Fisher Exact Tests and unpaired Welch t tests to assess for associations with positive bone cultures. RESULTS: In our cohort, 33 patients (91.7%) had positive bone cultures with the 3 most common organisms being candida (22.0%), enterococcus (18.0%), and pseudomonas (10.0%). There was a correlation between positive preoperative urine culture and positive bone culture (P <.01), with 63.0% of those with positive urine cultures growing the same organism on bone culture. CONCLUSION: In this series, 91.7% of patients undergoing extirpative surgery for UPF at our institution have positive bone cultures at time of pubic bone debridement. Additionally, we demonstrate a statistically significant correlation between positive urine cultures and positive bone cultures in these patients. This supports the need for a multidisciplinary approach including infectious disease, orthopedic surgery and reconstructive urology in order to address this complex clinical condition.

AIMS: Measuring the urethral circumference accurately during artificial urethral sphincter (AUS) placement is an important technical aspect to optimize the selection of cuff size. Differing methods exist for this step with some experts recommending measurement with no urethral catheter in place. In this prospective observational trial, we compared urethral measurements with and without an indwelling catheter to determine if the presence of a catheter affects the circumferential measurement. METHODS: With IRB approval, we prospectively collected data on consecutive cases of transperineal male AUS implantation. Urethral circumference was measured with no urethral catheter (0 French [Fr]), 12Fr, and 16Fr Foley catheters in the urethra. The final measurements and cuff size chosen were recorded. A comparison was made between each measurement using Spearman's correlation coefficient. RESULTS: A total of 54 patients were included, the majority of whom (92.6%) underwent AUS placement for postprostatectomy incontinence. The three urethral circumference measurements were highly correlated (0Fr vs 12Fr, ρ = 0.96, P < .001, mean difference 1 mm) (0Fr vs 16Fr, ρ = 0.94, P < .001, mean difference 2 mm) (12Fr vs 16Fr, ρ = 0.96, P < .001, mean difference 1 mm). Patients with a history of radiation had a lower mean urethral circumference than those who had never been radiated (4.78 cm vs 5.3 cm, P = .01). CONCLUSIONS: Urethral circumference measurement during AUS implantation is not influenced by the presence of a 12 or 16Fr Foley catheter when compared to no catheter in the urethra. Measurement of the urethral circumference can, therefore, be accurately performed with or without a catheter in place, depending on the surgeon's preference.

BACKGROUND: Cancers comprise a significant proportion of urologic workload. The epidemiology of prostate and renal cancers is well described. We report the incidence, survival and predictors of survival for non-prostate, non-renal urologic cancers between 1977 and 2013. METHODS: All patients in the South Australian Cancer Registry diagnosed with bladder, testis, penis, renal pelvis, ureteric and other male genital organ cancers between 1977 and 2013 were included. Demographic data included age, sex, year of diagnosis, grade, and metropolitan/rural status. Changes in incidence, survival and predictors of survival are reported for each cancer type. RESULTS: Between 1977 and 2013, bladder cancer was the most common of the studied urologic cancers (6465/9317). Age standardized incidence rate for bladder cancer decreased from 15.6-9.0 per 100,000 in 2013 (Annual Percentage Change (APC) -0.97 %, p < 0.05 %). Between 1977 and 2013 mortality has increased in patients with bladder cancer (HR 1.01 per year, p = 0.004). Testicular cancer diagnoses increased from 1.7 to 4.7 per 100,000 through 1977-2012 (APC 2.41 %, p < 0.05 %). Survival has increased (HR 0.95 per year, p < 0.001). Incidence of penile cancers has increased from 0.23 to 0.46 per 100,000 (APC 2.8 %); Penile cancer survival has remained static (HR 1.02 p = 0.23).Five and ten year survival estimates were highest for testicular cancer - 93.4 % and 91.1 % respectively; and lowest for renal pelvis - 36.3 % and 24.6 %. CONCLUSION: The incidence of non-prostate, non-renal urologic cancers remains low and stable. The age-standardized incidence of testicular cancer has increased whilst there has been a decline in the age-standardized incidence of bladder cancer. Bladder cancer survival has decreased since the 1970s.

BACKGROUND: High concentrations of local anaesthetic have an anti-proliferative effect on colonic cancer in vitro. Intraperitoneal local anaesthetic (IPLA) has shown analgesic benefit and improved recovery in the perioperative setting. The long-term effects of IPLA in colon cancer resection have not been examined. This study aims to review the survival and oncological outcomes of a previously conducted trial that compared perioperative IPLA with placebo. METHODS: Sixty patients underwent colonic resection for benign and malignant disease as part of a double-blinded, randomized, placebo-controlled study between September 2008 and November 2009. The IPLA group received instillation of intraperitoneal ropivacaine before dissection followed by a 3-day infusion. The placebo group was treated identically but with 0.9% saline solution. A follow-up analysis was conducted to evaluate overall survival, disease-free survival and recurrence specifically for patients undergoing resection for stages I-III colon cancer. Kaplan-Meier analysis was performed, and the log-rank test was used to evaluate difference in survival between groups. RESULTS: Thirty-seven of the 60 patients had stages I-III colon cancer and were included in this analysis. Nineteen patients were in the placebo group. There was no significant difference in overall survival or all-cause mortality. There was a higher incidence of cancer-specific mortality in the local anaesthetic group (P < 0.046). CONCLUSION: It does not appear that IPLA is associated with a significant survival benefit in patients with colonic malignancy undergoing colectomy. Other studies are needed to analyse the long-term outcomes.

Posterior urethral stenosis (PUS) is an uncommon but challenging problem following prostate cancer therapy. A review of the recent literature on the prevalence of PUS and treatment modalities used in the last decade was performed. A summative narrative of current accepted techniques in management of PUS is presented, and supplement with our own experience and algorithms.
RESUMEN
PURPOSE: We evaluated the management of recurrent bulbar urethral stricture disease after urethroplasty at our institution. MATERIALS AND METHODS: We performed an institution review board approved, retrospective case study of our urethroplasty database to collect stricture related and postoperative information with an emphasis on bulbar urethral stricture disease recurrence after urethroplasty between 1996 and 2012. Repair types included primary anastomotic, augmented anastomotic and onlay repair. Recurrence, which was defined as the need for intervention, was diagnosed with cystoscopy or retrograde urethrogram. RESULTS: We identified 437 men who underwent urethroplasty of bulbar urethral stricture disease as performed by 2 surgeons from January 1996 to December 2012. Of the men 395 had available followup data. Recurrence was identified in 25 men (6.3%), of whom all presented with symptoms, including a weak stream in 23, urinary tract infection in 1 and pyelonephritis in 1. Median time to recurrence was 10 months. Recurrence was initially treated endoscopically in 23 of 25 cases (92%), dilatation in 12 and visual urethrotomy in 11. In 5 patients (22%) further recurrence developed after endoscopic treatment, which was managed by repeat urethroplasty in 2, self-calibration only in 2 and visual urethrotomy with subsequent self-calibration in 1. We identified 2 distinct phenotypes of recurrent stricture, including type A-short focal recurrence, which may be salvaged with an endoscopic procedure, and type B-the long graft length type, which is less likely to be salvaged with endoscopy. CONCLUSIONS: Recurrence after urethroplasty is most likely to develop within the first 12 months. Type A short focal recurrence may be managed by a salvage endoscopic procedure, including dilation or visual urethrotomy. These data on the phenotype of recurrence may be useful for patient treatment.
