ABSTRACT Objective To assess testicular volumes and sexual maturation in patients with testicular torsion. Methods A retrospective analysis of consecutively treated patients with testicular torsion between 2016 and 2018. Age, pubic hair staging (Tanner), and by ultrasonography, volume of the unaffected testis (in cubic centimeters) were evaluated either immediately before surgery or at the first postoperative visit. Patients with previous testicular disease, such as cryptorchidism, or with no records of testicular volume were excluded. The analysis included descriptive statistics and Bayesian regression. Results We treated 149 patients during the study period, and 141 (94.6%, median age 17.3 years) met the inclusion criteria. Median testicular volume was 13.0cm3 (interquartile range of 10.5-15.2), with similar right and left volumes (12.9cm3versus 13.3cm3; p=0.94). Sixty-five (46.1%) patients were Tanner stage IV, 17 (12.1%) stage III, and 59 (41.8%) stage V. Conclusion In this study, we were able to estimate volumes of testicular torsion, which aggregated around late puberty values (13.0cm3 for the whole dataset, 12.2cm3 for patients <25 years), suggesting that testicular hypermobility, due to congenital anatomical abnormalities, remains quiescent until the organ reaches a critical volume, after which torsion becomes possible. These findings provide a tentative explanation for the disease’s age distribution.

ABSTRACT Purpose To estimate statewide presentation delay, misdiagnosis rate, inter-hospital transfer times and testicular salvage for testicular torsion patients treated in our state’s public health system. Patients and Methods Case series of consecutive testicular torsion patients treated in our state’s public health system between 2012-2018. Predictors included presentation delay (time from symptoms to first medical assessment), facilitie’s level-of-care (primary, secondary, tertiary), first diagnosis (torsion, epididymitis, other), Doppler-enhanced ultrasound request (Doppler-US) and inter-hospital transfer times, with surgical organ salvage as the main response. We used Bayesian regression to estimate the effect of first examining facilitie’s level-of-care, first diagnosis, and Doppler-US on transfer time. Results 505 patients were included, most (298, 59%) with presentation delay >6 hours. Misdiagnosis at first examining facility raised transfer time from median 2.8 to 23.4 (epididymitis) and 37.9 hours (other) and lowered testicular salvage rates from 60.3% (torsion) to 10.7% (epididymitis) and 18.3% (other). Doppler-US had negligible effects on transfer time once controlling for misdiagnosis in the regression model. Although organ salvage in patients presenting before 6 hours at the tertiary facility was high (94.6%, and about 20% lower for those presenting at lower levels-of-care), the overall salvage rate was more modest (46%). Conclusion Our low overall testicular salvage rates originated from a large proportion of late presentations combined with long transfer times caused by frequent misdiagnoses. Our results indicate that efforts to improve salvage rates should aim at enhancing population-wide disease awareness and continuously updating physicians working at primary and secondary levels-of-care about scrotal emergencies.

ABSTRACT Purpose: To analyze pre-transplantation and early postoperative factors affecting post-transplantation urine output and develop a predictive nomogram. Patients and Methods: Retrospective analysis of non-preemptive first transplanted adult patients between 2001-2016. The outcomes were hourly diuresis in mL/Kg in the 1st (UO1) and 8th (UO8) postoperative days (POD). Predictors for both UO1 and UO8 were cold ischemia time (CIT), patient and donor age and sex, HLA I and II compatibility, pre-transplantation duration of renal replacement therapy (RRT), cause of ESRD (ESRD) and immunosuppressive regimen. UO8 predictors also included UO1, 1st/0th POD plasma creatinine concentration ratio (Cr1/0), and occurrence of acute cellular rejection (AR). Multivariable linear regression was employed to produce nomograms for UO1 and UO8. Results: Four hundred and seventy-three patients were included, mostly deceased donor kidneys’ recipients (361, 70.4%). CIT inversely correlated with UO1 and UO8 (Spearman's p=-0.43 and −0.37). CR1/0 inversely correlated with UO8 (p=-0.47). On multivariable analysis UO1 was mainly influenced by CIT, with additional influences of donor age and sex, HLA II matching and ESRD. UO1 was the strongest predictor of UO8, with significant influences of AR and ESRD. Conclusions: The predominant influence of CIT on UO1 rapidly wanes and is replaced by indicators of functional recovery (mainly UO1) and allograft's immunologic acceptance (AR absence). Mean absolute errors for nomograms were 0.08 mL/Kg h (UO1) and 0.05 mL/Kg h (UO8).

OBJETIVO: Avaliar a frequência de Sintomas Urinários Irritativos (SUI) três anos após o parto em mulheres previamente entrevistadas no terceiro trimestre da gestação e sua associação com a via de parto exclusiva, a paridade, a idade materna, o peso do RN, a realização da episiotomia e o uso de fórcipe. MÉTODOS: Das 340 mulheres, originalmente avaliadas no terceiro trimestre da gestação, 120 foram localizadas e entrevistadas por telefone, três anos após o parto, entre junho e outubro de 2006. Foi analisada a associação entre SUI e via exclusiva de parto (vaginalou cesáreo), paridade,idade materna, peso do recém-nascido, realização da episiotomia e uso de fórcipe. Os resultados foram avaliados por meio de estatística descritiva, teste Qui quadrado e cálculo da razão de prevalência (p< 0,05). RESULTADOS: O grupo de mulheres estudadas consistiu de primíparas (37,5%) e multíparas (62,5%). As 95 que tiveram via exclusiva de parto foram categorizadas em vaginal (53) e cesáreas (42). Não houve associação significativa entre a presença de SUI após o parto e a via de parto exclusiva e a paridade. Também não encontramos associação entre a presença de SUI e a idade materna (> 35) peso do recém-nascido (> 4000g), realização da episiotomia e uso de fórcipe. CONCLUSÃO: A via de parto e a paridade não foram fatores determinantes para a disfunção do trato urinário inferior após o parto, representada pelos sintomas urinários irritativos, tampouco, a idade materna, o peso do RN, a realização da episiotomia e o uso de fórcipe.

OBJECTIVE: This study intended to investigate the frequency of irritative bladder symptoms three years after delivery in women previously interviewed in the third trimester of pregnancy and its correlation to mode of delivery, parity, maternal age, birth weight, episiotomy and forceps. METHODS: From 340 women previously evaluated at the third trimester of pregnancy, 120 were interviewed three years after delivery, between June and October 2006. Correlation of postpartum irritative bladder symptoms and mode of delivery (exclusively vaginal or c-section), parity, maternal age, birth weight, episiotomy and forceps was analyzed. Associations between irritative bladder symptoms and obstetric parameters were assessed by the Fisher's exact test and Chi-square (p< 0.05). RESULTS: The study group consisted of 37.5% primiparous and 62.5% multiparous women. Mode of delivery was exclusively vaginal in 53 women and exclusively c-section in 42. No statistical difference was found between irritative bladder symptoms and mode of delivery and parity. No statistical difference was found between irritative symptoms and maternal age (> 35), birth weight (> 4000g), episiotomy and forceps. CONCLUSION: After childbirth, dysfunction of the lower urinary tract, characterized by irritative bladder symptoms, was not associated with mode of delivery, parity, maternal age, birth weight, episiotomy and forceps.
