Should the current guidelines for the treatment of varicoceles in infertile men be re-evaluated?

Male infertility is a major health burden worldwide. In the United Kingdom, the diagnostic and treatment pathway for male factor fertility is fragmented with wide variance in management and funding protocols. There is now a focus on potential overtreatment of couples with IVF and failure to treat male factors before considering assisted reproductive technology (ART). Despite this, contemporary Urological guidelines are not definitive in the indications for varicocele treatment, whilst the current National Institute for Health and Care Excellence (NICE) guidelines do not advocate surgical intervention. While controversy exists concerning the effects of varicocele treatment on natural pregnancy rates, there is growing evidence that varicocele treatment can have additional positive effects on fertility by reducing their impact on sperm DNA fragmentation and improving ART outcomes. Studies have demonstrated that azoospermic men may become oligospermic following varicocele intervention, obviating the need for surgical sperm retrieval. Sperm retrieval rates also increase following varicocele treatment in men with non-obstructive azoospermia. The contemporary literature demonstrates a clear clinical benefit for treating varicoceles in infertile men, which may be more cost-effective than proceeding to immediate ART. This review comprehensively evaluates the current indications for varicocele treatment, and it is proposed that these should be redefined in contemporary guidelines to reflect current advances in male fertility research.

Open removal of a migrated Gellhorn pessary and repair of a vesicovaginal fistula.

This is a case of a 91-year-old woman presenting with urinary incontinence following insertion of a Gellhorn pessary 10 months previously. She had unfortunately missed her 6 months appointment for a change of pessary as she was admitted to hospital. Our patient was found to have had erosion of her Gellhorn shelf pessary into her urinary bladder. She underwent an open removal of the migrated Gellhorn pessary in the bladder and repair of the vesicovaginal fistula with omental interposition. She recovered well and has elected to keep her suprapubic catheter long-term.

Testicular Rupture or Testicular Fracture? A Case Report and Literature Review.

Testicular trauma is relatively uncommon. However, severe injuries can result in many complications and should be carefully diagnosed and managed. We present a case of testicular fracture diagnosis made by ultrasonography. The surgical exploration revealed the fracture as well as complete rupture of the tunica albuginea. Testicular rupture is the disruption of the tunica albuginea, while testicular fracture is a "break" in the testicular parenchyma. Management could be conservative in mild fracture cases without rupture while suspected or confirmed fracture should be treated by surgical exploration.

Laser ablation as monotherapy for penile squamous cell carcinoma: A multi-center cohort analysis.

INTRODUCTION: Although the trend towards penile sparing therapy is increasing for penile squamous cell carcinoma, outcomes for laser ablation therapy have not been widely reported. We assessed the clinical outcomes of penile cancer patients treated with only laser ablation. MATERIALS AND METHODS: A retrospective review was performed on 161 patients across 5 multi-center tertiary referral centers from 1985 to 2015. All patients underwent penile sparing surgery with only laser ablation for squamous cell carcinoma of the penis. Laser ablation was performed with neodymium-doped yttrium aluminum garnet or carbon dioxide. Overall and recurrence-free survival was calculated using the Kaplan-Meier method and compared with the log rank test. RESULTS: A total of 161 patients underwent laser ablation for penile cancer. The median age was 62 (IQR: 52-71) years and median follow-up was 57.7 (IQR: 28-90) months. The majority of patients were pTa/Tis (59, 37%) or pT1a (62, 39%). Only 19 (12%) had a poorly differentiated grade. The 5-year recurrence-free survival was 46%. When stratified by stage, the 5-year local recurrence-free survival was pTa/Tis: 50%; pT1a: 41%; pT1b: 38%; and pT2: 52%. The inguinal/pelvic nodal recurrence was pTa/Tis: 2%; pT1a: 5%; pT1b: 18%; and pT2: 22%. There were no differences among stages with respect to recurrence-free survival (P = 0.98) or overall survival (P = 0.20). CONCLUSION: Laser ablation therapy is safe for appropriately selected patients with penile squamous cell carcinoma. Due to the increased risk of nodal recurrence, laser ablation coupled with diagnostic nodal staging is indicated for patients with pT1b or higher.

Surgical management of penile carcinoma in situ: results from an international collaborative study and review of the literature.

OBJECTIVES: To evaluate recurrence after penile-sparing surgery (PSS) in the management of carcinoma in situ (CIS) of the penis in a large multicentre cohort of patients. PATIENTS AND METHODS: We identified consecutive patients from five major academic centres, treated between June 1986 and November 2014, who underwent PSS for pathologically proven penile CIS. The primary outcome was local recurrence-free survival (RFS), which was estimated using the Kaplan-Meier method. RESULTS: A total of 205 patients were identified. Treatment methods included circumcision, glansectomy, wide local excision, laser therapy and total glans resurfacing. Over a median (interquartile range [IQR]) follow-up of 40 (26-65.6) months, there were 48 local recurrences, with 45.8% occurring in the first year and 81.3% occurring by year 5. The majority of recurrences were observed in the laser group (58.3%). The median (IQR) time to local recurrence was 15.9 (5.66-26.14) months. The 1- 2- and 5-year RFS rates were 88.4, 85.6 and 75%, respectively, and the median (IQR) RFS time was 106.5 (80.2-132.2) months. CONCLUSIONS: Among patients with penile CIS selected for surgical management, durable responses at intermediate- to long-term follow-up were noted. For those with glandular CIS, glans resurfacing offered the best outcomes.

Penile Sparing Surgery for Penile Cancer: A Multicenter International Retrospective Cohort.

PURPOSE: We evaluated recurrence outcomes of penile sparing surgery in what is to our knowledge the largest multicenter cohort of patients to date. MATERIALS AND METHODS: We retrospectively identified patients treated with penile sparing surgery from May 1990 to July 2016 at 5 tertiary referral institutions. Treatments consisted of circumcision, wide local excision, laser therapy with or without local excision, partial or total glansectomy and glans resurfacing. The study primary end point was local recurrence-free survival, defined from initial treatment to time of local recurrence and estimated with the Kaplan-Meier method. RESULTS: After applying study exclusion criteria 1,188 patients were included in analysis. During the median followup of 43.0 months there were 252 local recurrences (21.2%), of which 99 (39.3%) developed in year 1. Median time to local recurrence was 16.3 months and the 5-year local recurrence-free survival incidence was 73.6%. When stratified by stage, the 5-year local recurrence-free survival rate was 75.0%, 71.4% and 75.9% in Ta/Tis, T1 and T2 cases, respectively (log rank p = 0.748). Of the recurrences 58.3% were treated with repeat organ sparing procedures and the secondary partial (total) penectomy rate was 19.0%. Only margin status was significantly associated with local recurrence on multivariate analysis (p = 0.001). Study limitations included the retrospective design and the heterogeneous clinical approach. CONCLUSIONS: Penile sparing surgery can provide excellent local control for superficial penile tumors as well as for appropriately selected invasive lesions. Strict followup in the early postoperative period is highly recommended.

Glansectomy as Primary Management of Penile Squamous Cell Carcinoma: An International Study Collaboration.

OBJECTIVE: To analyze the recurrence and survival outcomes of glansectomy in patients with penile squamous cell carcinoma. MATERIALS AND METHODS: We performed a retrospective review of 410 patients across 5 international tertiary referral centers between 1999 and 2016. All patients had tumors involving the glans penis and underwent glansectomy as primary treatment. The Kaplan-Meier method and log-rank test were used to calculate survival and recurrence. Median follow-up was 42 months (interquartile range [IQR] 29-56). RESULTS: The median age was 64 years (IQR 53-72). Median tumor size was 2.2 cm (IQR 1.5-3.0). A total of 240 patients (58.5%) had pT2 disease, whereas only 43 patients (10.5%) had pT3 or pT4 disease. The majority of the cohort had poorly differentiated tumors (43.7%). Most recurrences were local at 7.6% (31 patients). Only 14 patients (3.4%) had regional recurrence and 9 patients (2.2%) had distant recurrence. When stratified by pathologic stage, tumors that were pT2 or higher were (P < .001) and were more likely to be poorly differentiated (P < .001). There were no differences in recurrence location among pathologic stages (P = .15). The 1-, 2-, and 5-year recurrence-free survival were 98%, 94%, and 78%, respectively. There were no differences in overall survival when stratified by stage (P = .67). CONCLUSION: Glansectomy is an oncologically safe treatment modality for squamous cell carcinoma of the glans in appropriately selected invasive tumors.

Light deprivation induces depression-like behavior and suppresses neurogenesis in diurnal mongolian gerbil (Meriones unguiculatus).

Recent evidence suggests that adult neurogenesis contributes to the pathophysiology of different psychiatric disorders, including depressive disorder, anxiety disorder, and schizophrenia. Seasonal affective disorder (SAD) is a specific form of recurrent depressive disorder that can be induced by shortened light period. It is unclear yet whether neurogenesis is affected in SAD or under altered light/dark cycle. The present study aims at examining whether neurogenesis and dendritic growth of immature neurons are affected in Mongolian gerbils, a mainly diurnal rodent, under light deprivation. Animals were divided into two groups: the control (kept in 12 h light:12 h dark) and the light-deprived groups (kept in 24 h dark). Depression-like behaviors and neurogenesis were assessed after 2 weeks. Compared with the control group, light-deprived gerbils showed increased immobile time in the tail suspension test and forced swimming test, which indicates induction of depression-like behavior. Cell proliferation in both the hippocampal and subventricular zone were significantly decreased in the light-deprived group, which also showed a decreased neuronal differentiation. Dendritic maturation of immature neurons was suppressed by light deprivation, which is revealed by doublecortin staining and Sholl analysis. The results revealed that the light/dark cycle exerts impacts on neurogenesis and maturation of new neurons. Additionally, the current experiment may offer a model for exploring the relationship among daylight exposure, circadian cycles, depressive behavior, and the underlying mechanisms.
