Phallus preservation and reconstruction: 5-year outcomes of national penile cancer centralisation in the Republic of Ireland.

INTRODUCTION: Penile cancer is a rare urological malignancy with an age-standardised incidence of 0.8 per 100,000 person-years [1]. Given this low incidence it has been suggested that centralised care may improve patient outcomes in relation to phallus sparing surgery and nodal assessment [2]. We aim to assess the outcomes after 5-years of national centralisation of penile cancer care. METHODS: A retrospective analysis of prospectively collected data was performed. All patients undergoing penile cancer surgery from January 2018 to December 2022 following centralisation of care were included. The primary outcome was proportion of phallus sparing procedures performed. Secondary outcomes were patient characteristics, histologic outcomes and procedures performed. RESULTS: 124 patients underwent surgery in the study period. Mean age was 64.49 (±13.87). Overall, 82.3% of patients underwent phallus sparing surgery. This remained stable over the 5-year period from 2018 to 2022 â€‹at 92%, 85%, 76%, 79% and 78% respectively (p â€‹= â€‹0.534). 62.7% had reconstruction performed, including split-thickness skin graft neoglans formation, (57.8% [n â€‹= â€‹37]), preputial flap (32.8% [n â€‹= â€‹21]), glans resurfacing (4.7% [n â€‹= â€‹3]), shaft advancement flap (1.6% [n â€‹= â€‹1]), penile shaft skin graft (1.6% [n â€‹= â€‹1]), and partial penectomy with urethral centralisation (1.6% [n â€‹= â€‹1]). Phallus preservation was not affected by positive nodal status (OR 0.75 [95% CI 0.249-2.266], p â€‹= â€‹0.564) or T-stage ≥1b (OR 0.51 [95% CI 0.153-1.711], p â€‹= â€‹0.276). There has been a significant reduction in Nx nodal status from 64% in 2017 to 15% in 2021 (p â€‹= â€‹0.009). CONCLUSION: Centralisation of treatment for rare malignancies such as penile cancer may improve oncologic outcomes and rates of phallus preservation. This study has shown centralisation to has a high rate of phallus preservation. Further long-term analysis of outcomes in Ireland is required.

Diagnosis and management of indeterminate testicular lesions.

The sophistication and accessibility of modern-day imaging result in frequent detection of small or equivocal lesions of the testes. Traditionally, diagnosis of a testicular lesion with any possibility of malignancy would usually prompt radical orchidectomy. However, awareness is growing that a substantial proportion of these lesions might be benign and that universal application of radical orchidectomy risks frequent overtreatment. Given the potentially profound effects of radical orchidectomy on fertility, endocrine function and psychosexual well-being, particularly in scenarios of an abnormal contralateral testis or bilateral lesions, organ-preserving strategies for equivocal lesions should be considered. Image-based active surveillance can be applied for indeterminate lesions measuring ≤15 mm with a low conversion rate to surgical treatment. However, these outcomes are early and from relatively small, selected cohorts, and concerns prevail regarding the metastatic potential of even small undiagnosed germ cell tumours. No consensus exists on optimal surveillance (short interval (<3 months) ultrasonography is generally adopted); histological sampling is a widespread alternative, involving inguinal delivery of the testis and excisional biopsy of the lesion, with preoperative marking or intraoperative ultrasonographic localization when necessary. Frozen section analysis in this context demonstrates excellent diagnostic accuracy. Histological results support that approximately two-thirds of marker-negative indeterminate solitary testicular lesions measuring ≤25 mm overall are benign. In summary, modern imaging detects many small indeterminate testicular lesions, of which the majority are benign. Awareness is growing of surveillance and organ-sparing diagnostic and treatment strategies with the aim of minimizing rates of overtreatment with radical orchidectomy.

Penile cancer in younger men-A more aggressive disease?

INTRODUCTION: Penile cancer (PC) in men under 45 is very rare with an incidence of 0.1 to 0.8/100,000. There is little published data on disease characteristics and outcomes of PC in younger men. Herein, we evaluate the disease characteristics and outcomes of penile cancer in younger men compared to an older cohort. METHODS: This study included all men diagnosed with PC at our institution from 2016 to 2021. Primary outcomes included overall survival, cancer-specific survival, and disease-free survival. Secondary outcomes included disease characteristics and surgical management. Men aged ≤45 years (Group A) were compared with men aged >45 years (Group B) at diagnosis. RESULTS: There were 90 patients treated for invasive PC over the study period. The median age at diagnosis was 64 (26-88). The mean length of follow-up was 27 (±18) months. There were 12 (13%) in Group A, and 78 (87%) patients in Group B. Group A had a worse cancer-specific survival compared to Group B (39 months vs. not reached, HR 0.1 (95%CI 0.02-0.85, P = 0.03). There was no significant difference in overall or disease-free survival between both groups. More men in Group A had lymph node metastases at the time of diagnosis (58% vs. 19%, P < 0.001). There was no significant difference in histopathological features including tumor subtype, grade, T stage, p53 status or presence of lymphovascular or perineural invasion. CONCLUSION: In our study, younger men were more likely to have nodal involvement at time of diagnosis and had a worse cancer-specific survival.

Functional outcomes and health-related quality of life following penile cancer surgery: a comprehensive review.

INTRODUCTION: Organ-sparing surgery (OSS) in penile cancer management aspires to maintain organ form and function and preserve health-related quality of life (HRQoL), yet there is a lack of integrated evidence exploring these outcomes. OBJECTIVES: The aim sought to review HRQoL, functional, aesthetic, and psychological outcomes following OSS or radical penectomy for penile cancer. METHODS: A systematic review of MEDLINE and Cochrane databases included studies reporting on function (sexual, urinary or sensory), genital appearance or HRQoL/psychological well-being following surgical treatment of primary penile cancer. English-language reports (2000-2022), incorporating patient-reported or objective clinical outcome measures, were eligible. Studies of nonsurgical treatment strategies and those in the context of metastatic disease were excluded. Data were compiled and analyzed. RESULTS: Twenty-six studies were included. Sexual function was the most studied outcome (754 pooled respondents; 19 studies), most frequently with the original 15-item and abridged 5-item International Index of Erectile Function. Preservation of erectile function following OSS is generally described, with some reduction in overall sexual satisfaction cited. Heterogeneous assessment of voiding function with little preoperative evaluation render interstudy comparison difficult. Most patients appear able to void from a standing position following OSS, with spraying the most common symptom. Maintenance of some sensory function is described with both split-thickness skin grafting and urethral glanduloplasty following radical glansectomy. Limited studies suggest reasonable patient satisfaction with genital cosmesis post-OSS. A negative impact on HRQoL is described in most studies following penile cancer surgery, variably correlated with aggressiveness of penile surgery and addition of lymphadenectomy. Anxiety, depression, and reduced self-esteem have been reported in penile cancer survivors. Relationship well-being varies, with some survivors reporting this to be unchanged. CONCLUSION: OSS can preserve elements of sexual, urinary, and sensory function, supporting advantages over radical penectomy for eligible patients. However, a comprehensive understanding remains limited due to small, heterogeneous patient cohorts, challenges in obtaining premorbid data, and variability in outcome measures. Standardization of patient-reported outcomes following OSS is desirable.

The role of tissue biomechanics in the implantation and performance of inflatable penile prostheses: current state of the art and future perspective.

INTRODUCTION: Erectile dysfunction (ED) affects to some degree approximately 52% of the male population aged 40-70 years. Many men do not respond to, or are precluded from using, pharmaceutical treatments for ED and are therefore advised to consider penile prostheses. Different types of penile prosthesis are available, such as inflatable penile prostheses (IPPs). IPPs consist of a pair of inflatable cylinders inserted into the corpora cavernosa (CC). During inflation/deflation of these cylinders, the CC and other surrounding tissues such as the tunica albuginea (TA) are highly impacted. Therefore, it is critical to understand the mechanics of penile tissues for successful implantation of IPPs and to reduce tissue damage induced by IPPs. OBJECTIVES: We explored the importance of the biomechanics of penile tissues for successful IPP function and reviewed and summarized the most significant studies on penile biomechanics that have been reported to date. METHODS: We performed an extensive literature review of publications on penile biomechanics and IPP implantation. RESULTS: Indenters have been used to characterize the mechanical behavior of whole penile tissue; however, this technique applied only local deformation, which limited insights into individual tissue components. Although one reported study addressed the mechanical behavior of TA, this investigation did not consider anisotropy, and there is a notable absence of biomechanical studies on CC and CS. This lack of understanding of penile tissue biomechanics has resulted in computational models that use linear-elastic materials, despite soft tissues generally exhibiting hyperelastic behavior. Furthermore, available benchtop/synthetic models do not have tissue properties matched to those of the human penis, limiting the scope of these models for use as preclinical testbeds for IPP testing. CONCLUSION: Improved understanding of penile tissue biomechanics would assist the development of realistic benchtop/synthetic and computational models enabling the long-term performance of IPPs to be better assessed.

Extra-mammary Paget's disease of the penis.

Paget's disease was first described in 1874 as an eczematoid changes of the nipple associated with underlying breast carcinoma. Extra-mammary Paget's disease (EMPD) is rare with involvement of the male genitalia described in small case series and management options varying according to location and extent. The diagnosis of EMPD requires a high index of clinical suspicion and close liaison with the multidisciplinary team, particularly histopathology. We present two cases of EMPD affecting the male external genitalia that highlight important learnings in the presentation, diagnosis, and management of EMPD.

Surgical treatment of urachal remnants in an adult population-a single-centre experience.

BACKGROUND: Urachal remnants are a rare congenital defect resulting from failure of obliteration of a fibrous tube that connects the umbilicus to the bladder dome during embryological development. Oftentimes a urachal remnant will go undiagnosed, but occasionally a patient may present with a variety of symptoms, ultimately leading to the identification of the remnant. Given its rarity, there is very limited literature available on the management of symptomatic urachal remnants, especially in adults. Surgical resection has been the first-line management of urachal remnants for years, especially given the risk of the development of urachal adenocarcinoma secondary to recurrent infection, persistent irritation, and urinary stasis associated with some urachal remnants. AIM: We present our experience in the management of symptomatic urachal remnants in adults at our institute and perform a brief literature review of the same. METHODS: A retrospective review of all cases who underwent surgical management of symptomatic urachal remnants between December 2015 and January 2022 was performed. Seven cases of urachal remnant excision in total were identified over the time period. Patient characteristics and perioperative parameters were analysed. Post-operative complications were measured in accordance with the Clavien-Dindo grading system. RESULT: In total, 7 cases of urachal remnants were treated at our institute over the study period. Four patients were treated with a TURBT and 3 patients were treated with a laparoscopic partial cystectomy. There were no intraoperative complications and one post-operative complication requiring readmission for intravenous antibiotics. There was one mortality but this was not as a direct result of the operative procedure. Mean length of stay was 1.71 days. Two of patients had histologically confirmed urachal adenocarcinoma and the remaining five patients had benign histology. Each patient was seen in the outpatients department 6 weeks post-operatively for clinical review and review of histology. No further follow-up was required for the patients with benign histology given resolution of symptoms and follow-up for the malignant histology was arranged appropriately following MDM. CONCLUSION: There is a paucity of data available on the management of urachal remnants in the adult population; however, an endoscopic or laparoscopic approach is a safe and effective method of excising symptomatic urachal remnants.

Reconstruction of the male external genitalia in diverse disease processes: Our reconstructive algorithm, techniques, and experience.

Background: Male genital form and function may be rendered abnormal by a number of disease processes, with profound associated psychological and functional consequences. The aim of the study is to review our reconstructive experience with cases of genital loss or distortion due to nonmalignant diseases processes and atypical neoplasia. Materials and methods: A retrospective review of a prospectively maintained database was performed to identify reconstructive cases performed from 2018 to 2020 under the care of a single surgeon. Male patients 18 years or older with a disease diagnosis other than squamous cell carcinoma affecting genital form were included. Disease processes, patient factors, surgical techniques, and both functional and cosmetic outcomes were reviewed. Results: Fourteen cases were identified. The patients had a mean age of 52.2 years (range, 21-72 years). Acquired buried penis was present in 8 patients. Etiology of genital abnormality included balanitis xerotica obliterans (n = 6), excess skin loss at circumcision (n = 2), self-injection of petroleum jelly to penile shaft (n = 1), Fournier gangrene (n = 1), hidradenitis suppurativa (n = 1), extramammary Paget disease (n = 1), idiopathic lymphoedema (n = 1), and penoscrotal webbing (n = 1). Reconstructive techniques performed included penile debridement/shaft skin release, scrotectomy, suprapubic apronectomy, and division of penoscrotal webbing, in combination with split-thickness skin grafting where required. A penile implant was inserted in one patient. Reconstructive planning, techniques, and outcomes are described. Conclusions: A variety of reconstructive techniques in andrology can be used to improve the aesthetic and functional outcomes of multiple disease processes affecting the male external genitalia.

En bloc transurethral resection of bladder tumors: A review of current techniques.

INTRODUCTION: Growing interest surrounds the concept of en bloc transurethral resection of bladder tumors (ERBT). Theoretical advantages include improved adherence to oncological principles and potential yield of superior pathological specimens. Multiple ERBT methods exist. This review summarizes the current evidence regarding application of differing techniques and technologies to ERBT. METHODS: A systematic review of MEDLINE/EMBASE/Scopus databases was performed, using terms "en bloc," "ERBT," "bladder," and "urinary bladder neoplasm." Template-based data extraction included technique of ERBT, feasibility, tumor size, activation of obturator nerve reflex, operative complications, detrusor muscle sampling rate, and recurrence data. RESULTS: Multiple approaches to ERBT have evolved, using a variety of energy sources. The feasibility of electrocautery, laser, combined waterjet/electrocautery, and polypectomy snare techniques have been confirmed in achieving ERBT. ERBT appears safe, with a low complication rate. The use of laser energy sources reduces the risk of activating the obturator nerve reflex during lateral wall resections. Otherwise, no energy source is unequivocally superior in achieving ERBT. The rate of detrusor muscle sampling is high with use of ERBT and appears superior to that achieved with conventional TURBT (cTURBT) in multiple comparative studies. A limited number of largely non-randomized trials assess bladder tumor recurrence; current evidence suggests this is similar between ERBT and cTURBT groups. CONCLUSIONS: ERBT using a variety of technologies is feasible and safe, with a high detrusor muscle sampling rate. Further research is required to determine whether rates of residual disease or recurrence can be reduced with ERBT vs. cTURBT.

The relationship of human papillomavirus positivity with tumor characteristics in an Irish penile cancer population.

INTRODUCTION: Penile cancer is a rare malignancy, with a European-wide annual incidence rate of 1/100 000 males. Approximately one-third of cases are attributable to human papillomavirus (HPV) infection. p16INK4a is a recognized surrogate marker for HPV infection in penile cancer. University Hospital Waterford (UHW) is the national referral center for penile cancer in Ireland. We report the prevalence of HPV infection and histological characteristics of an Irish penile cancer cohort using p16INK4a as a surrogate marker. METHODS: Patients who attended UHW for penile cancer surgery between June 2015 and November 2020 were entered into a prospectively maintained database. Clinical, histopathological, and outcome data were collected. RESULTS: Over the study period, 70 patients with a histological diagnosis of penile squamous cell carcinoma had staining for p16INK4a, of whom 64% were positive. p16INK4a-positive patients were significantly younger at diagnosis, with a mean age of 61±15 years compared to 68±12 (p <0.05). Of note, 97% of tumors with high-risk histology were p16INK4a-positive (p<0.001). p16INK4a positivity was more prevalent among higher-grade tumors (p<0.02). Interestingly, p16INK4a status was not associated with recurrence-free or overall survival. CONCLUSIONS: Our data is representative of the Irish landscape in penile cancer over the last five years. Using p16INK4a staining, we demonstrate a high rate of HPV prevalence in penile cancer cases in our patient cohort, which is associated with prognostically worse tumor subtypes. This would suggest that HPV vaccination of adolescent boys is a useful public health intervention in preventing penile cancer in the Irish male population.

The Pull-through Anastomosis of Ureter to Enteric Conduit (PAUTEC): A Novel Technique for Urinary Diversion.

OBJECTIVE: To describe and illustrate a novel technique of uretero-ileal anastomosis for use in urinary diversion - the Pull-through Anastomosis of Ureter To Enteric Conduit (PAUTEC). A second objective was to evaluate the surgical outcomes of the PAUTEC anastomosis. MATERIALS AND METHODS: Our novel anastomotic technique was described step-by-step and visually depicted with illustrations and the accompanying narrated video. Additionally, to evaluate safety and efficacy, a retrospective review of a prospectively maintained database was performed. Patients who underwent radical cystectomy alone or during pelvic exenteration, with ileal conduit diversion incorporating PAUTEC, 2016-2020 with ≥6 months follow-up were included. Surgical outcomes and renal function were analysed. RESULTS: PAUTEC anastomosis was performed on 43 ureters in 23 patients. Mean age was 66 years [50-80] and 21 of 23 patients were male. One patient had a conservatively-managed small urine leak. No ureteric strictures have been identified to date. Mean serum creatinine was 1.15 mg/dL [0.69-2.08] (102umol/L, range 61-184 umol/L) preoperatively, and 1.09 mg/dL [0.61-2.59] (96.3 umol/L, range 54-229 umol/L) at follow-up, demonstrating no significant change (P= .26, paired t-test). Mean follow-up was 15 months [6-44]. CONCLUSION: A PAUTEC technique of uretero-ileal anastomosis is feasible and technically straightforward, with satisfactory outcomes observed to date.

Long-Term Surveillance and Laparoscopic Management of Zinner Syndrome.

Zinner syndrome was first described in 1914 and represents the triad of unilateral renal agenesis and ipsilateral seminal vesicle cyst and ipsilateral ejaculatory duct obstruction. Seminal vesicle cysts are often asymptomatic but can also present with pain, haematospermia, or other lower urinary tract symptoms. Treatment strategies include observation and surgical excision. We present the laparoscopic management of an enlarged seminal vesicle cyst, consistent with Zinner syndrome, 14 years after the initial diagnosis. A 58-year-old male patient was diagnosed with a left-sided seminal vesicle cyst while undergoing assessment for renal transplant due to progressively worsening renal function in his solitary right kidney. The otherwise asymptomatic cyst enlarged from the time of initial diagnosis in 2004 (11.3 cm × 9.7 cm × 13.1 cm) to nearly double the size in 2018 (12.8 cm × 11.9 cm × 14.2 cm). This cyst size ultimately precluded renal transplant, and the patient was referred for excision. Laparoscopic excision of the cyst was performed, histopathology confirmed seminal vesicle cyst tissue, and there has been no recurrence of the cyst to date. The patient remains active on the renal transplant waitlist. Zinner syndrome is a rare syndrome, with the seminal vesicle cysts being managed by observation or surgical excision. We report the longest documented observation of a seminal vesicle cyst, culminating in a safe and successful laparoscopic excision.

Phallus Preservation in Penile Cancer Surgery: Patient-reported Aesthetic & Functional Outcomes.

OBJECTIVE: To assess patient-reported outcomes of oncoplastic penile reconstruction using standardized questionnaires. Whilst organ-preserving penile cancer surgery has evolved, aiming to preserve genital function, reduce psychological morbidity of radical penectomy, and maximise patient quality of life, few studies have evaluated patients' final perceptions. METHODS: Following ethical approval, patients post partial/radical glansectomy with reconstruction 2016-2019, under a single surgeon, were identified. Patients were posted a modified Index of Male Genital Image, the IIEF-5, a customised questionnaire exploring outcomes of urinary and sensory function and the EORTC QLQ-C30 to complete and return. Questionnaires were nonidentifiable, however study ID linked responses to the procedure performed. RESULTS: A total of 130 questionnaires were received from 35 patients post penile reconstruction, giving a response rate of 71.4% (35/49). Mean time from surgery was 22 months (4-51), and mean age 61 years (31-79). The majority (82.4%, n = 28) were satisfied or felt neutral about the appearance of their genitalia. High satisfaction with postprocedure urinary function was reported; 85.3% (29/34) could void from a standing position and 79.4% (27/34) reported little or no spraying of urine. Nineteen patients (55.89%) were sexually active, with mean IIEF-5 scores of 14.9 (5-25) (partial glansectomy) and 15.8 (5-25) (radical glansectomy). Mean QoL over past week on 7-point EORTC QLQ-C30 scale was 5.88 (3-7). CONCLUSION: We report good aesthetic and functional outcomes in a unique study exploring penile cancer surgery patient-reported outcome measures. These results strongly support phallus-preserving phallic-preserving strategies as the standard of care in eligible patients undergoing penile cancer surgery.

Paratesticular sarcomas: a case series and literature review.

Paratesticular soft tissue tumours are remarkably rare entities, with malignant subtypes accounting for approximately 30%. Due to the paucity of cases, a consensus on the best treatment has not yet been reached, presenting a diagnostic and therapeutic challenge for clinicians. Although rare, three such cases presented to the care of our institution serving a population of approximately 400,000 in the space of 13 months. These were three gentlemen, aged 54, 82 and 86 years old, presenting with left sided testicular swellings. Ultrasound in each case confirmed an extratesticular mass. Only the second gentleman complained of associated pain, however he had experienced scrotal trauma in the preceding weeks. Only one patient had suspicions of metastatic disease, with a 9 mm pulmonary nodule on computed tomography. All patients underwent a radical inguinal orchidectomy with high ligation of the spermatic cord, in keeping with best accepted guidelines. Histology confirmed a well-differentiated liposarcoma, a dedifferentiated liposarcoma and a leiomyosarcoma respectively, all high grade. One gentleman returned to theatre for re-excision of margins. Our case series emphasises the need for full multidisciplinary team specialist sarcoma input, as well as radical resection with judicious margins in order to reduce the risk of local recurrence, in the treatment of these rare tumours.

The dangers of hurling-genital injuries arising in the modern game.

OBJECTIVE: To assess the proportion of penoscrotal injuries arising from the sport of hurling and to assess work-up and management of each injury. METHODS: Using Hospital In-Patient Enquiry data, all penoscrotal injuries occurring over a 10-year period between 2007 and 2017 were identified and assessed. Chart review, imaging reports, operative notes and discharge summaries were used to identify the aetiology of each injury and those occurring due to hurling were selected for analysis. Investigations and management of each case were reviewed. RESULTS: Seventy patients presented to our institution over a 10-year period with penoscrotal injuries and, of these, ten patients (14%) presented with injuries arising due to blunt scrotal trauma whilst playing hurling. The average age of these patients was 24.3 years, and the right testicle was injured six times, compared with the left testicle twice and isolated scrotal injuries twice also. One hundred percent of patients underwent diagnostic ultrasonography with Doppler flow assessment with 90% (n = 9) having positive findings. Three patients (33%) required operative management with only one patient (10%) requiring an orchidectomy. There were no delayed or interval procedures. CONCLUSION: Hurling is a physical sport with a notable proportion of blunt scrotal trauma arising due to the sport. Prompt physical examination and diagnostic ultrasonography are essential in investigations of injuries, and surgical exploration should be considered in all cases with concerns of testicular survival. Groin protection should be recommended to all players and in particular to those at high risk such as single testis or prior injury.

To tube or not to tube? Utilising a tubeless antegrade ureteric stenting system in a tertiary referral hospital.

INTRODUCTION: To assess the benefits and complications of developing a practice of single-stage primary ureteral stenting in a university hospital. METHODS: A practice change developed from the traditional practice of multi-stage stenting to single-episode stent placement. To evaluate this change of practice, we retrospectively analysed data of 70 patients who underwent primary tubeless antegrade ureteric stenting and compared this group to the previous 54 patients who had a covering nephrostomy. RESULTS: There was an overall success rate of 91.3% (85/93 stents having had tubeless antegrade stenting). There were no major and 33 minor complications. The comparative group of 54 patients whose stents had a covering nephrostomy had a median length of stay of 13.2 days compared to 7.4 days for the tubeless group. CONCLUSION: Single-stage primary ureteric stenting is a safe practice to employ and has universal benefits for both the patient and the health service.

Methicillin-resistant Staphylococcus aureus as a uropathogen in an Irish setting.

Urinary tract infections are one of the most common infectious diseases diagnosed in the community and in the hospital setting. Their treatment is complicated by drug-resistant pathogens and the colonization by microbes of indwelling urinary catheters. This study assessed the occurrence and antimicrobial susceptibility of methicillin-resistant Staphylococcus aureus (MRSA) uropathogens isolated for 5 consecutive years at University Hospital Waterford between 2010 and 2014. We created 4 clinically relevant subdivisions, based on urine source: hospital inpatients, patients from the Emergency Department, patients referred from their General Practitioner, and Nursing Home patients. We performed a retrospective review from the hospital's electronic microbiological system and calculated resistance rates for each of the standard antimicrobial agents. During the 5-year study period, we studied 151 urine isolates obtained from 128 patients who had an MRSA cultured in their urine sample. There was 100% resistance of all MRSA isolates to Flucloxacillin and Coamoxiclav. Ninety-eight percent of isolates were resistant to Ciprofloxacin. The resistance rate for Trimethoprim was 7.4% and there was only 2.7% resistance for Nitrofurantoin. For a clinical subset of patients, we also demonstrated 100% sensitivity for samples tested against Teicoplanin and Vancomycin. Urinary MRSA is an infrequently studied phenomenon, but with the rising trend of hospital superbugs nationally, its management is of critical importance. Suitable agents to address this within our population include Nitrofurantoin in the well patient requiring urinary MRSA eradication or Vancomycin/Teicoplanin in the unwell patient requiring intravenous therapy. In all groups, fluoroquinolones should be avoided due to significant resistance rates.

Pursuit of sexual function post-radical prostatectomy.

INTRODUCTION: In the event of the implementation of prostate cancer screening, younger men will be diagnosed more frequently. Erectile dysfunction (ED) is a frequent long-term complication in men post-radical prostatectomy (RP). Since the introduction of RP, urologists have strived to improve postoperative sexual function. There is little literature, however, in the area of ED prescribing and sexual pursuit in men post-RP. We assessed the pursuit of sexual function in this group of patients. METHODS: The study involved a detailed questionnaire sent to patients who have undergone radical retropublic prostatectomy (RRP) by one surgeon in one institution to ascertain the impact of ED on lifestyle and ED therapy prescription use. RESULTS: There was a response rate of 59%; most patients who responded were in the 61 to 70 year age group at the time of the survey. About 25% of patients had intercourse more than once in the 4 weeks prior to the survey. A total 50% of patients had no problem or a very small problem with their sexual function. Overall 80% of patients were prescribed ED therapy, but less than 35% of them used it. CONCLUSION: Sexual frequency peaked in younger patients who were 3 years or more from surgery. Of note, 46% of men either declined the offer of ED therapy or got the prescription and never used it. Only 34% of men had used their ED prescription in the last 4 weeks. Urologists frequently find that patients behave differently postoperatively, with less interest in sexual activity. Interestingly, we found that 50% of our patients classified their sexual function, as at most a small problem.

Prospective study of antibiotic prophylaxis for prostate biopsy involving >1100 men.

We aimed to compare infection rates for two 3-day antibiotic prophylaxis regimens for transrectal ultrasound-guided prostate biopsy (TRUSgbp) and demonstrate local microbiological trends. In 2008, 558 men and, in 2009, 625 men had TRUSgpb. Regimen 1 (2008) comprised 400 mg Ofloxacin immediately before biopsy and 200 mg 12-hourly for 3 days. Regimen 2 (2009) comprised Ofloxacin 200 mg 12-hourly for 3 days commencing 24 hours before biopsy. 20/558 (3.6%) men had febrile episodes with regimen 1 and 10/625 (1.6%) men with regimen 2 (P = 0.03). E. coli was the most frequently isolated organism. Overall, 7/13 (54%) of positive urine cultures were quinolone resistant and (5/13) 40% were multidrug resistant. Overall, 5/9 (56%) patients with septicaemia were quinolone resistant. All patients were sensitive to Meropenem. There was 1 (0.2%) death with regimen 1. Commencing Ofloxacin 24 hours before TRUSgpb reduced the incidence of febrile episodes significantly. We observed the emergence of quinolone and multidrug-resistant E. coli. Meropenem should be considered for unresolving sepsis.

Prospective randomised controlled trial comparing trigone-sparing versus trigone-including intradetrusor injection of abobotulinumtoxinA for refractory idiopathic detrusor overactivity.

BACKGROUND: Botulinum toxin A is effective for treatment of idiopathic detrusor overactivity (IDO). The trigone is generally spared because of the theoretical risk of vesicoureteric reflux (VUR), although studies assessing injection sites are lacking. OBJECTIVE: Evaluate efficacy and safety of trigone-including versus trigone-sparing intradetrusor injections of abobotulinumtoxinA in patients with IDO. DESIGN, SETTING, AND PARTICIPANTS: Twenty-two patients from one centre were randomised to trigone-including or trigone-sparing injections. INTERVENTION: Injection of 500 U abobotulinumtoxinA diluted to 20ml into 20 trigone-including or trigone-sparing sites. MEASUREMENTS: The primary outcome measure was total overactive bladder symptom score (OABSS) at 6 wk. The OABSS questionnaire was completed at 0, 6, 12, and 26 wk. Baseline and postinjection urodynamic studies and micturating cystourethrograms were performed. Baseline values and subsequent time points were compared by t test. A mixed-effect model was used for repeated measures in time. RESULTS AND LIMITATIONS: For symptom scores at baseline compared with scores at 6 wk postinjection, the mean total OABSS improved from 22.4 to 8.7 (p<0.001) in the trigone-including group compared with 22.7 to 13.4 (p<0.03) in the trigone-sparing group. The difference in mean change from baseline was 4.4 points in favour of the trigone-including group (p=0.03). The total OABSS at 12 and 26 wk and the urgency subscale scores at 6, 12, and 26 wk showed significant improvement in favour of the trigone-including group. Mean postvoid residual volumes and clean intermittent self-catheterisation rates between the two groups were similar. No patients developed VUR. Performing injections under general anaesthetic was a limitation, as tolerability under local anaesthetic was not assessed. A further limitation is the lack of a trigone-only arm. CONCLUSIONS: Trigone-including injections are superior to trigone-sparing injections for the treatment of refractory IDO and did not cause VUR in this study.
