ABSTRACT
ABSTRACT Objective: To evaluate the length hospital stay and predictors of prolonged hospitalization after RRP performed in a high-surgical volume teaching institution, and analyze the rate of unplanned visits to the office, emergency care, hospital readmissions and perioperative complications rates. Materials and Methods: Retrospective analysis of prospectively collected data in a standardized database for patients with localized prostate cancer undergoing RRP in our institution between January/2010 - January/2012. A logistic regression model including preoperative variables was initially built in order to determine the factors that predict prolonged hospital stay before the surgical procedure; subsequently, a second model including both pre and intraoperative variables was analyzed. Results: 1011 patients underwent RRP at our institution were evaluated. The median hospital stay was 2 days, and 217 (21.5%) patients had prolonged hospitalization. Predictors of prolonged hospital stay among the preoperative variables were ICC (OR. 1.40 p=0.003), age (OR 1.050 p<0.001), ASA score of 3 (OR. 3.260 p<0.001), prostate volume on USG-TR (OR, 1.005 p=0.038) and African-American race (OR 2.235 p=0.004); among intra and postoperative factors, operative time (OR 1.007 p=0.022) and the presence of any complications (OR 2.013 p=0.009) or major complications (OR 2.357 p=0.01) were also correlated independently with prolonged hospital stay. The complication rate was 14.5%. Conclusions: The independent predictors of prolonged hospitalization among preoperative variables were CCI, age, ASA score of 3, prostate volume on USG-TR and African-American race; amongst intra and postoperative factors, operative time, presence of any complications and major complications were correlated independently with prolonged hospital stay.

ABSTRACT Objective: To present our technique of ureteroileal bypass to treat uretero-enteric stric- tures in urinary diversion. Materials and Methods: One hundred and forty-one medical records were reviewed from patients submitted to radical cystectomy to treat muscle-invasive bladder cancer between 2013 and 2015. Twelve (8.5%) patients developed uretero-enteric anastomotic stricture during follow-up. Five patients were treated with endoscopic dilatation and double J placement. Four were treated surgically with standard terminal-lateral im- plantation. Three patients with uretero-enteric anastomotic stricture were treated at our institution by "ureteroileal bypass", one of them was treated with robotic surgery. Results: All patients had the diagnosis of uretero-enteric anastomotic stricture via computerized tomography and DTPA renal scan. Time between cystectomy and diag- nosis of uretero-enteric anastomotic stricture varied from five months to three years. Mean operative time was 120±17.9 minutes (98 to 142 min) and hospital stay was 3.3±0.62 days (3 to 4 days). Mean follow-up was 24±39.5 months (6 to 72 months). During follow-up, all patients were asymptomatic and presented improvement in ure-terohydronephrosis. Serum creatinine of all patients had been stable. Conclusions: Latero-lateral ureter re-implantation is feasible by open or even robotic surgery with positive results, reasonable operation time, and without complications.

Summary Objective: To evaluate the relation between serum total testosterone (TT) and prostate cancer (PCa) grade and the effect of race and demographic characteristics on such association. Method: We analyzed 695 patients undergoing radical prostatectomy (RP), of whom 423 had serum TT collected. Patients were classified as having hypogonadism or eugonadism based on two thresholds of testosterone: threshold 1 (300 ng/dL) and threshold 2 (250 ng/dL). We evaluated the relation between TT levels and a Gleason score (GS) ≥ 7 in RP specimens. Outcomes were evaluated using univariate and multivariate analyses, accounting for race and other demographic predictors. Results: Out of 423 patients, 37.8% had hypogonadism based on the threshold 1 and 23.9% based on the threshold 2. Patients with hypogonadism, in both thresholds, had a higher chance of GS ≥ 7 (OR 1.79, p=0.02 and OR 2.08, p=0.012, respectively). In the multivariate analysis, adjusted for age, TT, body mass index (BMI) and race, low TT (p=0.023) and age (p=0.002) were found to be independent risk factors for GS ≥ 7. Among Black individuals, low serum TT was a stronger predictor of high-grade disease compared to White men (p=0.02). Conclusion: Hypogonadism is independently associated to higher GS in localized PCa. The effect of this association is significantly more pronounced among Black men and could partly explain aggressive characteristics of PCa found in this race.
Resumo Objetivo: Avaliar a relação entre testosterona sérica total (TT) e grau do câncer de próstata (CP) e o efeito da raça e de características demográficas sobre essa associação. Método: Foram analisados 695 pacientes submetidos a prostatectomia radical (PR), dos quais 423 tinham medidas dos níveis séricos de TT. Os pacientes foram classificados como portadores de hipogonadismo ou eugonadismo com base em dois limites de testosterona: limite 1 (300 ng/dL) e limite 2 (250 ng/dL). Avaliou-se a relação entre nível de TT e escore Gleason (GS) ≥ 7 em amostras de PR. Os resultados foram avaliados por análises univariada e multivariada, com ajuste para raça e outros fatores prognósticos demográficos. Resultados: Do total de 423 pacientes, 37,8% apresentavam hipogonadismo com base no limite 1, e 23,9% com base no limite 2. Os pacientes com hipogonadismo, independentemente do limite de referência, tiveram uma chance maior de GS ≥ 7 (OR 1,79, p=0,02 e OR 2,08, p=0,012, respectivamente). Na análise multivariada, após ajuste para idade, TT, índice de massa corporal (IMC) e raça, baixo TT (p=0,023) e idade (p=0,002) foram considerados fatores de risco independentes para GS ≥ 7. Entre os indivíduos negros, baixo TT sérico foi mais preditivo de doença de alto grau em comparação com os brancos (p=0,02). Conclusão: O hipogonadismo é independentemente associado a escores mais altos de GS no CP localizado. O efeito dessa associação é significativamente mais pronunciado entre homens negros, o que poderia explicar, em parte, as características agressivas do CP observadas nessa população.

To describe our experience with percutaneous nephrolithotomy (PCNL) in patients with solitary kidneys and analyze factors that can impact on intra-operative bleeding and postoperative complications.
We reviewed our stone database searching for patients with solitary kidney who underwent PCNL from Jan-05 through Oct-13. Demographic data, stone characteristics, and intra- and postoperative outcomes were recorded. Spearman correlation was performed to assess which variables could impact on bleeding and surgical complications. Linear and logistic regressions were also performed.
Twenty-seven patients were enrolled in this study. The mean age and BMI were 45.6 years and 28.8Kg/m2, respectively; 45% of cases were classified as Guys 3 (partial staghorn or multiple stones) or 4 (complete staghorn) – complex cases. Stone-free rate was 67%. Eight (29.6%) patients had postoperative complications (five of them were Clavien 2 and three were Clavien 3). On univariate analysis only number of tracts was associated with increased bleeding (p=0.033) and only operative time was associated with a higher complication rate (p=0.044). Linear regression confirmed number of access tracts as significantly related to bleeding (6.3, 95%CI 2.2-10.4; p=0.005), whereas logistic regression showed no correlation between variables in study and complications.
PCNL in solitary kidneys provides a good stone-free rate with a low rate of significant complications. Multiple access tracts are associated with increased bleeding.
