Can we avoid surgery in elderly patients with renal masses by using the Charlson comorbidity index

To determine the safety of surveillance for localized contrast‐enhancing renal masses in elderly patients whose comorbidities precluded invasive management; to provide an insight into the natural history of small enhancing renal masses; and to aid the clinician in identifying those patients who are most suitable for a non‐interventional approach.

Positive apical surgical margins after radical retropubic prostatectomy, truth or artefact?

Objective: The significance of a positive apical surgical margin following radical retropubic prostatectomy has been the subject of controversy. We examined the hypothesis that a positive apical margin alone is not associated with an increased probability of biochemical relapse. Material and Methods: A total of 162 men underwent radical prostatectomy for clinically organ‐confined disease between May 1990 and December 1998. The mean follow‐up period was 55 months (minimum 24 months). The mean patient age was 60.8 years. Clinical staging was 67.9% T1 and 32.1% T2. The mean preoperative prostate‐specific antigen level was 11.5ng/ml, and the mean Gleason score was 5.8. Results: Overall, 5/64 patients (7.8%) with negative surgical margins and 42/98 (42.9%) with at least one positive surgical margin had biochemical recurrence (p < 0.001). Seven of 25 patients (28%) with a solitary positive apical margin relapsed. A solitary apical positive margin was associated with a statistically significant higher risk of recurrence versus controls (p < 0.05). Conclusion: All patients with a positive surgical margin, including those with a solitary apical margin alone, are at significantly increased risk of biochemical failure.

Sexual function outcomes following fracture of the penis.

INTRODUCTION Fracture of the penis is a rare urological emergency which occurs as a result of abrupt trauma to an erect penis. There is paucity of data regarding long-term sexual function or erectile potency following fracture of the penis. The aim of this study is to objectively assess the overall sexual function following fracture of the penis. METHODS A retrospective analysis of 21 penile fractures was performed. A voluntary telephone questionnaire was performed to assess long term outcomes using three validated questionnaires-the Erection Hardness Grading Scale, the International Index of Erectile Function (IIEF-5) and the Brief Male Sexual Function inventory (BMSFI). RESULTS The mean age was 33.1 years (range: 19-63). The median follow up was 46 months (range: 3-144). All fractures were a result of sexual misadventure and all were surgically repaired. There were two concomitant urethral injuries. Seventeen patients were contactable. Fourteen patients demonstrated no evidence of erectile dysfunction (ED) (IIEF-5>22), 1 patient reported symptoms of mild ED (IIEF-5, 17-21) and one patient reported mild to moderate ED (IIEF-5, 12-16). No patients reported insufficient erection for penetration (EHGS: 1 or 2). Regarding the overall BMSFI, 13 (83%) patients were mostly satisfied or very satisfied with their sex life within the previous month. CONCLUSION In a small surgical series of men with penile fracture managed within a short time frame from presentation, we demonstrate erectile potency is maintained. Long-term overall sexual satisfaction is promising.

Can prostate biopsies predict suitability for nerve-sparing radical prostatectomy?

Objective: The process for selecting patients suitable for nerve‐sparing radical prostatectomy (NSRP) has been the source of much debate. In this study we analysed the use of prostate biopsies as the principal selection tool. Material and Methods: Patients undergoing radical retropubic prostatectomy (n = 133) were retrospectively categorized as having “unilateral” (biopsy demonstrated malignancy confined to one side of the gland) or “bilateral” carcinoma. The accuracy and reliability of this categorization were determined by correlation with the final histopathology of the resected radical prostatectomy specimen. Results: Prostate biopsy suggested “unilateral” carcinoma in 30/58 (52%) and 45/75 (60%) patients diagnosed using transrectal ultrasound‐guided (TRUS) and transperineal digital‐guided (TP) routes, respectively. Subsequent analysis of the resected specimen, however, revealed “bilateral” malignancy in 50 patients (86%) in the TRUS group and in 63 (84%) in the TP group. Furthermore, positive surgical margins were identified on the “benign” side (by preoperative biopsy) in 6 (20%) patients in the TRUS subgroup whose biopsy had suggested “unilateral” carcinoma, and in 12 (27%) of the comparative TP subgroup. Conclusions: Biopsy‐suggested “unilateral” carcinoma was associated with both a high incidence of “bilateral” disease on final histology following radical prostatectomy and an alarming incidence (24%) of positive surgical margins on the “benign” side where NSRP might be advocated.

A Narrative Review on the Pathophysiology and Management for Radiation Cystitis

Radiation cystitis is a recognised complication of pelvic radiotherapy. Incidence of radiation cystitis ranges from 23 to 80% and the incidence of severe haematuria ranges from 5 to 8%. High quality data on management strategies for radiation cystitis is sparse. Treatment modalities are subclassified into systemic therapies, intravesical therapies, and hyperbaric oxygen and interventional procedures. Short-term cure rates range from 76 to 95% for hyperbaric oxygen therapy and interventional procedures. Adverse effects of these treatment strategies are acceptable. Ultimately, most patients require multimodal treatment for curative purposes. Large randomised trials exploring emergent management strategies are required in order to strengthen evidence-based treatment strategies. Urologists encounter radiation cystitis commonly and should be familiar with diagnostic modalities and treatment strategies.

The value of appropriate assessment prior to specialist referral in men with prostatic symptoms

BackgroundReferrals to Urology OPD of men with a likely diagnosis of BPH are common.AimsTo review referrals to OPD of men with lower urinary tract symptoms (LUTS) to establish how many could have been managed without specialist assessment.MethodsWe reviewed records of 200 male patients referred to OPD with LUTS. We assessed whether the referral source had performed digital rectal examination (DRE), International Prostate Symptom Score (IPSS), Bother Score or PSA level.Results74% of patients were referred by GPs. In 31.5% of cases DRE was performed prior to referral. One GP had completed an IPSS, none a Bother Score. 96% had a PSA checked before OPD. Ultimately, 88.5% of our patients were diagnosed with BPH.ConclusionsWith better pre-assessment in the form of DRE, IPSS and Bother Score, allied to a PSA check, many patients with LUTS could be managed in a primary care setting.

Can delayed time to referral to a tertiary level urologist with an abnormal PSA level affect subsequent gleason grade in the opportunistically screened population

There is growing conflict in the literature describing the effect of delayed treatment on outcomes following radical prostatectomy. There is also evidence to suggest progression of low‐risk prostate cancer to develop higher grades and volumes of prostate cancer during active surveillance. It is unknown as to what affect a delay in referral of those men with abnormal screened‐PSA levels have on subsequent Gleason grade.

Incidentalology: A developing urological sub-specialty

OBJECTIVE To identify the incidence and features of significant incidental findings discussed at our departmental multidisciplinary team meeting (MDM). The improved quality of radiological imaging has resulted in increased rates of incidental findings. Although some may be trivial, many have clinical significance and early diagnosis and treatment may be beneficial. METHODS A retrospective analysis was performed of all cases discussed at the MDM between January 2012 and February 2013. Cases were divided into two groups--Group 1 consisted of patients whose initial imaging was performed for a urological presentation which resulted in a synchronous finding; Group 2 consisted of patients who were referred with a synchronous urological finding for discussion following investigation of an initial benign urological condition or a non-urological condition. RESULTS 696 patients were discussed at 53 MDMs. 109 (15.7%) patients had incidental findings. 61 (56%) of these were in Group 1. 16 (26.2%) were synchronous malignant diagnoses, 25 (41%) were benign and 20 (32.8%) were indeterminate. 48 (44%) patients in Group 2 - 40 (83.3%) were renal in origin and 30 (75%) of these proceeded to surgery. The median tumour size was 3.2 cm (Range: 1.2 cm-10 cm). One patient had radio-frequency ablation. Two were referred for palliative care. Seven patients are under ongoing surveillance--the median size of these lesions is 3.6 cm (Range: 2.1 cm-8.3 cm). CONCLUSION A substantial workload is generated from the investigation of incidental findings discussed at MDM--these now represent the majority of the caseload for renal cancer surgery.

Should patients with a pre-operative prostatespecific antigen greater than 15ng/ml be offered radical prostatectomy?

AbstractBackground Patients with prostate cancer with a pre-operative prostate-specific antigen (PSA) τ;15ng/ml who undergo radical retropubic prostatectomy (RRP) generally do not have a good outcome, yet may have organ-confined cancer and should be offered the option of surgery. Aim To assess the outcome of patients who underwent RRP with a pre-operative PSA ≥ 15ng/ml. Methods Thirty-four patients, mean pre-operative PSA: 25.46ng/ml (15.03–76.6) and mean Gleason score: 6.4 (5–9) were assessed. Results Two groups were identified. Group I: 41% (14/34) have no biochemical recurrence to mean follow up of 58 months (30–106). Mean PSA: 18.8ng/ml (15.03–25.84). Mean Gleason score: 6.1 (5–7). Clinical stage: T1c in 80%. No patient had seminal vesicle or lymph node involvement. Group II: 59% (20/34) have biochemical recurrence or died (3) from their disease to mean follow up of 66 months (36–98). Mean PSA: 28.9ng/ml (15.28–76.6). Mean Gleason score: 6.7 (5–9). Clinical stage: T1c in 25%. Eleven patients had seminal vesicle (8) involvement or positive lymph nodes (3) or both (2). Conclusion RRP seems feasible in patients whose pre-operative PSA is between 15 and 25ng/ml with stage T1c, Gleason score ≤ 7 and negative lymph node frozen section.

Clinico-pathological analysis of renal cell carcinoma demonstrates decreasing tumour grade over a 17-year period

INTRODUCTION Renal cell carcinoma (RCC) represents about 3% of adult malignancies in Ireland. Worldwide there is a reported increasing incidence and recent studies report a stage migration towards smaller tumours. We assess the clinico-pathological features and survival of patients with RCC in a surgically treated cohort. METHODS A retrospective analysis of all nephrectomies carried out between 1995 and 2012 was carried out in an Irish tertiary referral university hospital. Data recorded included patient demographics, size of tumour, tumour-node-metastasis (TNM) classification, operative details and final pathology. The data were divided into 3 equal consecutive time periods for comparison purposes: Group 1 (1995-2000), Group 2 (2001-2006) and Group 3 (2007-2012). Survival data were verified with the National Cancer Registry of Ireland. RESULTS In total, 507 patients underwent nephrectomies in the study period. The median tumour size was 5.8 cm (range: 1.2-20 cm) and there was no statistical reduction in size observed over time (p = 0.477). A total of 142 (28%) RCCs were classified as pT1a, 111 (21.9%) were pT1b, 67 (13.2%) were pT2, 103 (20.3%) were pT3a, 75 (14.8%) were pT3b and 9 (1.8%) were pT4. There was no statistical T-stage migration observed (p = 0.213). There was a significant grade reduction over time (p = 0.017). There was significant differences noted in overall survival between the T-stages (p < 0.001), nuclear grades (p < 0.001) and histological subtypes (p = 0.022). CONCLUSION There was a rising incidence in the number of nephrectomies over the study period. Despite previous reports, a stage migration was not evident; however, a grade reduction was apparent in this Irish surgical series. We can demonstrate that tumour stage, nuclear grade and histological subtype are significant prognosticators of relative survival in RCC.
