RESUMO

Testicular cancer is the most common form of cancer in young men of reproductive age and its incidence is increasing globally. With the currently successful treatment and 95% survival rate, there is a need for deeper understanding of testicular cancer-related infertility. Most patients with testicular cancer experience semen abnormalities prior to cancer therapy. However, the exact mechanism of the effect of testicular cancer on sperm anomalies is not known. Mitochondria are organelles that play a crucial role in both tumorigenesis and spermatogenesis and their malfunction may be an important factor resulting in sperm abnormalities in testicular cancer patients. Within the scope of this review, we will discuss current knowledge of testicular cancer-related alterations in the ATP production pathway, a possible pathophysiological switch from oxidative phosphorylation (OXPHOS) to glycolysis, as well as the role of oxidative stress promoting sperm dysfunction. In this regard, the review provides a summary of the impact of testicular cancer on sperm quality as a possible consequence of impaired mitochondrial function including the energy metabolic pathways that are known to be altered in the sperm of testicular cancer patients.

RESUMO

INTRODUCTION AND HYPOTHESIS: The aim of this video is to provide a step-by-step description of our approach to the surgical management of intravesically localized transobturator tape after previous failure of repeated cystoscopic tape resection. METHODS: This video presents a patient with tape erosion to the urinary bladder after repeated cystoscopic tape resection, recurrent stone formation, and repeated lithotripsy, with recurrent urinary tract infections and overactive bladder (OAB) with urgency incontinence. RESULTS: During the laparoscopy procedure tape was identified in the left obturator muscle, cut near the obturator muscle, and dissected up to the bladder wall. Afterward, a vertical 2-cm incision was made in the bladder wall, the stone was removed, and the rest of the tape was dissected from the bladder wall. A two-layer suture of the bladder wall was performed. The postoperative course was uneventful. In follow-up visits 3 and 6 months after surgery the patient was continent with no symptoms of OAB. CONCLUSIONS: Cystoscopic resection of protruded mesh is inadequate in many cases. In such cases the mesh should be removed from the urinary bladder wall completely. Laparoscopy allows minimally invasive complete removal of the tape, combining resection of the extravesical and intravesical parts of the tape.

RESUMO

BACKGROUND: Surgery is the optimal treatment for a severe form of clitoral phimosis (CP) that is initiated by lichen sclerosus (LS) and causes female sexual dysfunction. AIM: We aimed to determine the etiology of clitoral phimosis, its influence on sexual function, and outcomes after surgical treatment. METHODS: In this prospective cohort study, we observed the occurrence of clitoral phimosis and related changes in a group of 3,650 sexually active heterosexual women with a mean age of 34.8 ± 14.9 years (20-45 years) from September 2014 to September 2016. Ultimately, we compared the changes in sexual function and distress and satisfaction with postoperative genital appearance in 9 patients with severe clitoral phimosis at 12 months after surgical treatment. MAIN OUTCOME MEASURES: Sexual function was evaluated using the Female Sexual Distress Scale-Revised and the Female Sexual Function Index, and the patient's genital self-image was evaluated using the Female Genital Self-Image Scale; gynecologic examinations were performed on all patients. RESULTS: Various forms of CP were found in 46 of 3,650 patients (1.3%). Severe forms of CP were found in 9 cases, but it was complicated by stenosis of vaginal introitus in only 2 cases. These 9 patients underwent circumcision, and 2 of them underwent perineoplasty. Female sexual dysfunction occurred mainly in those with LS and severe forms of phimosis. Sexual function, as indicated by the total Female Sexual Function Index score, was significantly improved at 12 months after surgery (17.9 ± 0.9 vs 26.6 ± 0.5; P < .001). The Female Genital Self-Image Scale score assessing genital perception was significantly higher after surgery than before in women who underwent clitoral circumcision (20 ± 3.0 vs 12.3 ± 3.3; P < .001). The Female Sexual Distress Scale-Revised score was significantly lower after surgery than before (21.3 ± 6.2 vs 33.8 ± 6.9; P < .001). Sexual function in 2 women with CP and stenosis of vaginal introitus improved after surgery, but the sexual distress level did not decrease significantly. CLINICAL IMPLICATIONS: The results of this study will help clinicians to centralize treatment methods and advise patients on the management of clitoral phimosis. STRENGTHS & LIMITATIONS: This is a study evaluating postoperative results of sexual function, distress, and satisfaction with genitalia in women with severe CP, using validated questionnaires. However, the small number of patients and the absence of an appropriate control group are limitations. CONCLUSION: Surgical treatment of clitoral phimosis can improve sexual function, but because LS-a common underlying cause-is chronic in nature, patients may experience recurrence.

RESUMO

INTRODUCTION AND HYPOTHESIS: A urethrovaginal fistula is a possible rare complication of tension-free vaginal tape procedures. Surgical management of these fistulas is sometimes complicated, and failure can occur. The operation is difficult when the defect between the urethra and the vagina is larger or scarred, so surgical intervention and the preferred technique are controversial. METHODS: The patient was referred to our department, where the first operation was performed to address the urethrovaginal fistula by the transvaginal and transabdominal approach with interposed omentum. This initial repair failed, resulting in a large urethrovaginal fistula with minimal redundant anterior vaginal wall to provide a tension-free closure. This video presentation describes the second operation-transvaginal repair of a large recurrent urethrovaginal fistula using the skin island flap technique. RESULTS: The video of the procedure shows how to address a recurrent urethrovaginal fistula by employing a skin flap. An examination during the patient's follow-up visit 3 months later revealed excellent healing and persistent stress urinary incontinence (SUI). Six months after the fistula repair, the patient underwent a bulking agent procedure. CONCLUSIONS: The skin island flap procedure allowed the larger defect to heal, though it did not address the SUI, which was later treated by application of a bulking agent.

RESUMO

INTRODUCTION: After spinal cord injury (SCI), individuals are typically considered by the general public to be asexual. Handicapped women have more problems with socio-sexual adaptation, stemming from low self-confidence, low self-esteem, and the absence of spontaneity. AIMS: To determine changes in the sexual lives of women after SCI. METHODS: A self-constructed questionnaire was used to map sexual function after SCI. We retrospectively compared sexual function in 30 women with SCI with that in 30 without SCI who led an active sexual life. Descriptive and inductive statistics were applied using the Student paired and non-paired t-tests and the Levene test. MAIN OUTCOME MEASURES: The main variables were presence vs absence of sexual dysfunction in a group of women after SCI and a comparison of the incidence of sexual dysfunctions in women after SCI with that of a control group. RESULTS: A significant difference was ascertained in women with SCI in sexual desire (P < .001), lubrication (P < .001), and reaching orgasm before and after injury (P = .030). A comparison of the two groups showed a significant difference in the realization of coital sexual activity (P < .001), erotogenous zones of the mouth (P = .016), nipples (P = .022), and genitals (P < .001), and in the ability to reach orgasm (P = .033). The negative impact of incontinence on the sexual life of women with SCI proved significant (P < .001). Negative factors for sexual activity in women with SCI were lower sensitivity in 16 (53%), spasms and mobility problems in 12 (40%), lower desire in 11 (36%), pain in 4 (13%), and a less accommodating partner in 3 (10%). CONCLUSION: Intercourse was the preferred sexual activity in women with SCI. Compared with the period before injury, there was significant lowering of sexual desire, impaired lubrication, and orgasmic ability after SCI. A comparison of the two groups showed a difference in erotogenous zones and in reaching orgasm. Sramkova T, Skrivanova K, Dolan I, et al. Women's Sex Life After Spinal Cord Injury.

RESUMO

OBJECTIVES: Vascular erectile dysfunction (ED) predicts future development of cardiovascular diseases (CVD). We performed a study in men seeking consultant medical advice regarding vascular ED for the first time without a history of cardiovascular disease, diabetes mellitus or renal insufficiency. Our goal was to evaluate the prevalence of CVD risk factors in this cohort of patients. Furthermore, we assessed the prevalence of asymptomatic subclinical atherosclerosis. MATERIAL AND METHODS: All study subjects underwent a thorough physical examination including anthropometric measurements. Laboratory analyses comprising assessment of lipid spectrum, liver and kidney function tests, glycaemia and glycated haemoglobin were measured using automated analysers. Intima-media thickness of carotid arteries was measured using SONOS machine and ankle-brachial index using a mini-duplex device. CVD risk was calculated by standard SCORE charts. Chi-square test, t-test and ANOVA were used for statistical analysis. RESULTS: We examined 35 men, average age 46.5 ± 9.9 years. Six (17.1%) had a positive family history of CVD, 19 (54.3%) had dyslipidemia, 10 (28.6%) were obese, 9 (25.7%) were active smokers, and 14 (40.0%) had arterial hypertension. Eighteen (51.4%) subjects had subclinical atherosclerosis as determined by ABI and CIMT assessment. CONCLUSION: Patients with vascular erectile dysfunction have similar prevalence of CVD risk factors to general population.
