RESUMO
Objective: The present study aimed to evaluate the predictive value of bony pelvic parameters measured by computerized tomography (CT) for use in the estimation of the likely technical difficulties that may be encountered when performing open radical prostatectomy (RP) for localized prostate cancer. Material and methods: One hundred patients, undergoing open RP for localized prostate cancer, were evaluated between October 2016 to November 2018. All operations were performed by the same experienced surgeon. Pelvic parameters were measured using spiral CT images. Data were retrospectively collected from medical, operative, radiology, and pathology records and analyzed. Positive surgical margin (PSM), presence of vesicourethral anastomosis stricture (VUAS) and urine leakage, operative time, urethral catheterization time, and estimated blood loss were used as indicators of operative difficulty. Univariate and multivariate analyses were performed to determine the significance of these variables. Results: There was no significant correlation between the pelvic parameters of the patients and the presence of PSM, VUAS, and urine leakage. Only PSA levels and pathological tumor stage were higher in patients with PSM (p = 0.002 and p = 0.001). On univariate and multivariate analyses, none of the individual pelvic parameters assessed showed a significant relationship with the operation time, estimated blood loss, and urethral catheterization time. In univariate analysis, there was a significant relationship between PSA levels and pathological tumor stage and operation time (p = 0.048 and p = 0.001, respectively). Conclusion: Bony pelvic parameters may not be a significant factor in influencing the perioperative outcomes of open RP. Higher PSA levels and pathological tumor stage may lead to surgical margin positivity and longer operative time.
RESUMO
OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic disrupted all routine health care services and resulted in a significant reconfiguration of urologic cancer services and care pathways across the globe. This study aimed to retrospectively determine the pandemic's impact on the urologic oncological surgery outcomes at a high-volume referral center. MATERIALS AND METHODS: We compared the number and histopathological outcomes of urologic oncological procedures in a referral center coded during the pandemic and data of the period before the pandemic as control. Data were extracted from patient files and hospital records. The pathological examination included a complete histopathological staging according to TNM stage. RESULTS: A total of 683 patients were included in the study, 424 (62%) of which were operated in the pre-pandemic period. There was a 39% decline in urologic oncological surgical activity in the pandemic, mostly in renal and prostate cancer. The mean tumor size was larger in renal cancer patients who underwent surgery during the pandemic (5.6 cm vs 4.5 cm, p=0.002). During the pandemic, more lymph node involvement was seen after radical cystectomy and prostatectomy (50% vs 27.8%, p=0.024 and 12.5% vs 4.5%, p=0.026, respectively). No differences in terms of main pathologic features were observed in patients undergoing radical orchiectomy. CONCLUSION: COVID-19 appeared to adversely effect oncologic outcomes in patiens undergone surgery for prostate and bladder cancer. Tumor development induced by a delay in diagnosis may cause severe consequences for patients. Reprioritizion of non-deferrable urologic oncological seems crucial.
