RESUMO

Azoospermia is defined as absence of spermatozoa and may be secondary to blocked seminal ducts, known as obstructive azoospermia. Semen quality may be impaired due to factors such as sperm cell DNA fragmentation and presence of antisperm antibodies. The objective of this article was to investigate potential differences in outcomes of in vitro fertilisation and intracytoplasmic sperm injection between groups with different obstruction aetiology, as well as between the use of different techniques and sperm cells of different origins. Retrospective, multi-centre analysis of 621 first cycles was carried out between 2008 and 2015: Group I, congenital obstruction, 45 patients and Group 2, vasectomy, 576 patients. Sperm cell retrieval was achieved in all cases. Results were similar for Group I and II fertilisation rates, 70% versus 66.85% (p = .786); pregnancy rates, 42.5% versus 41.46% (p = .896); and live birth rates, 29.73% versus 17.69% (p = .071). According to sperm cell origin (579 epididymal vs. 42 testicular), pregnancy rates, 41.47% versus 43.9% (p = .760); and live birth rates, 18.3% versus 27.78% (p = .163) had no difference. Fertilisation, pregnancy and live birth rates did not differ according to obstruction aetiology. Outcomes did not differ between groups according to sperm cell origin.

RESUMO

INTRODUCTION: Peyronie's disease is characterized by abnormal healing of the tunica albuginea (TA), resulting in the production of a fibrotic plaque that leads to penile curvature and considerable psychological impact. Precise knowledge of various surgical techniques is of fundamental importance for proper management of the patient. AIM: To compare results (including surgical success on quality of life and sexual satisfaction and complications) between 2 different techniques: with TA incision vs without TA incision. METHODS: The search was performed according to PRISMA in PubMed and Embase through September 2018. Key words searched were ["Peyronie" or "Peyronie's disease" or "penile curvature" or "penile induration"] and ["technique" or "surgery" or "surgical"] and ["quality of life" or "sexual quality of life" or "sexual satisfaction" or "outcome" or "outcomes"]. MAIN OUTCOME MEASURE: Thirty-one articles were considered for this review. The main outcomes were reported descriptively. RESULTS: The most significant results included penile straightening (88.5% vs 70.9% favoring not opening TA), perception of a palpable nodule (13.2% vs 27.4% favoring not opening TA), and loss of sensibility (11% vs 20% favoring not opening TA). Neither a prospective randomized study nor a direct comparison study has been performed for these techniques. There is no consensus among the studies on how to measure results. Subjective criteria were primarily used for evaluation, and there is a paucity of objective tools to quantify the outcomes. CONCLUSION: There is no consensus on which technique achieves better results or fewer complications; therefore, the decision on which technique to use is a matter of surgeon preference. Studies comparing distinctive techniques and either opening or not opening the tunica albuginea should be performed to support surgical decision making. In addition, guidelines that could assist in the standardization of criteria should be investigated in future studies, with the aim of better evaluating outcomes.

RESUMO

BACKGROUND: Post-radical prostatectomy urinary incontinence (PPI) negatively affects the quality of life of patients. Accurate identification of the problem by physicians is essential for adequate postoperative management. In this study we sought to access whether there is, for urinary incontinence, any discrepancy between medical reports and the perception of patients. METHODS: We performed a retrospective analysis of medical records of 337 patients subjected to radical retropubic prostatectomy (RRP) between 2005 and 2010. Sociodemographic variables were collected, as well as continence status over the course of treatment. Next, we contacted patients by phone to determine continence status at present and at time of their last appointment, as well as to apply ICIQ - SF questionnaire. Poisson regression model with robust variance was used to estimate the factors associated with discrepancy, using the stepwise backward strategy. Software used was Stata® (StataCorp, LC) version 11.0. RESULTS: There is discrepancy between medical reports and patients' perceptions in 42.2% of cases. This discrepancy was found in 56% of elderly patients and 52% of men with low schooling, with statistical significance in these groups (p = 0.069 and 0.0001, respectively), whereas in multivariate regression analysis the discrepancy rate was significantly higher in black men (discrepancy rate of 52.6%) with low schooling (p = 0.004 and 0.043, respectively). CONCLUSION: There is discrepancy between medical reports and the perception of black men with low schooling in respect to post-radical prostatectomy urinary incontinence and a need for more thorough investigation of this condition in patients that fit this risk profile.

RESUMO

The purpose of this study is to investigate the relationship between inflatable penile prosthesis (IPP) infection, time of year, climate, temperature and humidity. This is a retrospective IRB-approved analysis of 211 patients at 25 institutions who underwent salvage procedure or device explant between 2001 and 2016. Patient data were compiled after an extensive review of all aspects of their electronic medical records. Climate data were compiled from monthly norms based on location, as well as specific data regarding temperature, dew point, and humidity from dates of surgery. Rigorous statistical analysis was performed. We found that penile prosthesis infections occurred more commonly in June (n = 24) and less frequently during the winter months (n = 39), with the lowest number occurring in March (n = 11). One-hundred thirty-nine infections occurred at average daily temperatures greater than 55 °F, compared to 72 infections at less than 55 °F. The incidence rate ratio for this trend was 1.93, with a p-value of <0.001. Humidity results were similar, and fungal infections correlate with daily humidity. Infected implants performed in the fall and summer were over 3 and 2.3 times, respectively, more likely to grow Gram-positive bacteria compared to implants performed in spring (p = 0.004; p = 0.039). This was consistent across geographic location, including in the Southern hemisphere. We found trends between climate factors and IPP infection like those seen and proven in other surgical literature. To our knowledge these data represent the first exploration of the relationship between temperature and infection in prosthetic urology.

RESUMO

OBJECTIVES: To assess the prevalence and interrelationship between lower urinary tract symptoms and sexual dysfunction in men with multiple sclerosis (MS). METHODS: In a cross-sectional study, we evaluated 41 men (mean age 41.1±9.9 years) with MS from February 2011 to March 2013, who were invited to participate irrespective of the presence of lower urinary tract symptoms or sexual dysfunction. Neurological impairment was assessed with the Expanded Disability Status Scale; lower urinary tract symptoms were evaluated with the International Continence Society male short-form questionnaire, and sexual dysfunction was evaluated with the International Index of Erectile Function. All patients underwent transabdominal urinary tract sonography and urine culture. RESULTS: The mean disease duration was 10.5±7.3 years. Neurological evaluation showed a median Expanded Disability Status Scale score of 3 [2-6]. The median International Continence Society male short-form questionnaire score was 17 [10-25]. The median International Index of Erectile Function score was 29 [15-46]. Twenty-nine patients (74.4%) had sexual dysfunction as defined by an International Index of Erectile Function score <45. Voiding dysfunction and sexual dysfunction increased with the degree of neurological impairment (r=0.02 [0.02 to 0.36] p=0.03 and r=-0.41 [-0.65 to -0.11] p=0.008, respectively). Lower urinary tract symptoms and sexual dysfunction also displayed a significant correlation (r=-0.31 [-0.56 to -0.01] p=0.04). CONCLUSIONS: Most male patients with MS have lower urinary tract symptoms and sexual dysfunction. The severity of the neurological disease is a predictive factor for the occurrence of voiding and sexual dysfunctions.

RESUMO

ABSTRACT Purpose: The baseline PSA has been proposed as a possible marker for prostate cancer. The PSA determination before 40 years seems interesting because it not suffers yet the drawbacks related to more advanced ages. Considering the scarcity of data on this topic, an analysis of PSA kinetics in this period seems interesting. Materials and Methods: A retrospective assay in a database of a private diagnostic center was performed from 2003 to 2016. All subjects with a PSA before 40 years were included. Results: 92995 patients performed PSA between the ages of 21 - 39. The mean value ranged from 0.66 ng / mL (at age 22) to 0.76 ng / mL (at age 39) and the overall mean was 0.73 ng / mL. As for outliers, 3783 individuals presented a baseline PSA > 1.6 ng / mL (p95). A linear regression model showed that each year there is a PSA increase of 0.0055 ng / mL (β = 0.0055; r2 = 0.0020; p < 0.001). A plateau in PSA between 23 and 32 years was found and there were only minimal variations among the ages regardless of the evaluated percentile. Conclusion: It was demonstrated that PSA kinetics before 40 years is a very slow and progressive phenomenon regardless of the assessed percentile. Considering our results, it could be suggested that any PSA performed in this period could represent the baseline value without significant distortions.

RESUMO

OBJECTIVE: To evaluate the effect of normal saline lavage of the distal vas deferens ampulla in patients undergoing vasectomy on the time to achieve azoospermia. METHODS: A prospective randomized study of 60 men divided into two groups, group lavage (GL, n=30) in which distal vas deferens ampulla lavage was performed with 10 ml of normal saline during the vasectomy, and group without lavage (GWL, n=30) in which control patients received only a vasectomy. The patients provided sperm for semen analysis at the 5th, 10th, 15th, 20th and 25th ejaculations. RESULTS: Fifteen participants in GL and 16 in GWL, for a total of 31 patients, were excluded due to not completing the control spermiogram. The tests carried out at the five ejaculations showed immobile spermatozoa in 40 and 85.71%, 66.67 and 78.57%, 93.33 and 85.71%, 86.67 and 71.43%, and 93.33 and 85.71% of participants in GL and GWL, respectively. CONCLUSION: Vas deferens duct lavage with 10 ml of normal saline during vasectomy did not decrease the time required to achieve postoperative azoospermia.

RESUMO

ABSTRACT Context: Polyacrylate-polyalcohol copolymer is a synthetic product, non-biodegradable, with low rate of therapeutic failure and lower incidence of reactions at the site of injection, when compared to biodegradable agents. We report an unprecedent, exuberant and persistent inflammatory reaction following injection of that substance. Patient: a 17 years-old patient with vesico-ureteral reflux and complete pyelocaliceal right duplication was submitted to treatment with polyacrylate-polyalcohol copolymer (STING technique). In the seventh day of post-operatory, she presented intense dysuria and hypogastric pain, without laboratory exams alterations; a symptomatic treatment was started. After two months, the symptoms persisted and an ultrasound detected thickening of bladder wall close to the uretero-vesical junction. After that exam, a cystostopic biopsy showed epithelial hyperplasia with increased edema of lamina propria, suggesting an adverse reaction to the polymer. After four months, there was complete remission, but the reflux persisted with the same grade. Hypothesis: This is an unprecedent reaction following injection of this copolymer. The presence of characteristics such as absence of infection, temporal relation between treatment and beginning of symptoms, and detection of epithelial hyperplasia at the local of injection reinforce the hypothesis of association of the substance and adverse reaction. In that patient, important complains motivated early investigation of urinary tract, that confirmed those aspects. Maybe if that reaction had occurred in patients with lower capacity of expression (such as in infants) it would be unnoticed.

RESUMO

INTRODUCTION: The impact of surgery for stress urinary incontinence (SUI) on female sexual function has received attention in the medical literature, but not in a structured manner. AIM: To assess the most recent evidence on the impact of surgical management for female SUI on female sexual function. METHODS: The review and meta-analysis of available articles published in Medline, Cochrane, LILACS, SCOPUS, Web of Science, CINHAL, and EMBASE included prospective randomized and non-randomized studies that assessed patients who underwent surgical treatment for UI through 2 validated questionnaires: the Pelvic Organ Prolapse Urinary Incontinence Sexual Questionnaire (PISQ-12) and the Female Sexual Function Index (FSFI). MAIN OUTCOME MEASURES: The following terms were searched: (urinary incontinence OR female OR woman OR women) AND (suburethral slings OR transobturator tape* OR transobturator suburethral tape OR trans-obturator tape* OR urethral sling* OR midurethral sling* OR mid-urethral sling* OR "standard midurethral slings" OR tensionless vaginal tape* OR mini sling* OR Burch* OR "Burch colposuspension" OR "urologic surgical procedures" OR "tension-free vaginal tape" OR pubovaginal sling) AND (sexual behavior OR "Female Sexual Function Index" OR FSFI OR sexual function OR "Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire" OR PISQ-12). RESULTS: 1,043 articles were retrieved; 9 studies were included for qualitative analysis and 4 were included for meta-analysis. 25 articles were excluded because they used questionnaires other than the FSFI and PISQ-12. Meta-analysis of 2 studies composed of 411 women who underwent to retropubic and transobturator sling intervention and completed the PISQ-12 questionnaire showed an increase in sexual function of 2.40 points after transobturator compared with retropubic sling intervention (95% CI = -2.48 to -2.32; I2 = 35%, P < .00001). However, 2 other studies composed of 183 women comparing the same techniques, but using the FSFI, did not show a statistically significant difference (95% CI = -1.77 to 3.78; I2 = 0%, P = .48). CONCLUSION: The impact of UI surgery on sexual function is uncertain because of the imprecision of the effect and inconsistency among studies. Only limited evidence on the impact of the transobturator vs the retropubic sling was found. Bicudo-Fürst MC, Borba Leite PH, Araújo Glina FP, et al.

RESUMO

The cause of Peyronie's disease (PD) is still not completely understood. The objective of this study, therefore, was to analyze the histological and biochemical alterations that occur after the instillation of blood in the tunica albuginea (TA) of rats with an emphasis on the remodeling process of ECM. Thirty male Wistar rats were divided into 4 groups: two control groups with instillation of distilled water in TA followed by penectomy after 15 days or 45 days, respectively and two experimental groups with instillation of blood in TA followed by penectomy after 15 days or 45 days, respectively. Histological, immunofluorescent and immunohistochemical analyses were performed. The higher presence of fibrotic tissue in rats injected with blood demonstrated alterations in TA similar to inflammation found in PD. The increased expression of TGF-ß, MMP9, HPSE, and biglycan associated with the decreased expression of syndecan-1 and aggrecan in the experimental groups suggested an enhancement in the remodeling of ECM. The results contribute to show that blood instillation on TA appears to trigger alterations in the ECM similar to the ones found in inflammatory diseases such as PD.
