RESUMEN
OBJECTIVES: The application of minimally invasive laparoscopic techniques in gynecologic surgery gained popularity due to quicker recovery, shorter hospital stays as well as lower risk of complications. Ureteric injuries at laparoscopic hysterectomies are incidental and occur in less than 1% of cases. They can be identified intra-operatively but most of them are undetected. In most cases, the symptoms of an injury are non-specifically manifested after several days or even months following surgery. MATERIAL AND METHODS: We described different clinical symptoms suggesting ureteric injury based on 3 laparoscopic hysterectomies. Methods of diagnosis and repair techniques were also presented. CONCLUSIONS: All complications following laparoscopic hysterectomy should be analyzed meticulously and ureteral injury must be considered as one of the possible causes of abnormal patient recovery.

INTRODUCTION: The aim of the study was to identify predictors of surgical complications of transurethral resection of bladder tumour (TURBT). MATERIAL AND METHODS: We prospectively recruited 983 consecutive patients undergoing TURBT within 7 months in six academic institutions. All patients were followed up from the surgery up to 30 days postoperatively with at least one telephone contact at the end of the observation. The primary study endpoint was any intra- or postoperative surgical complication. For the identification of predictors of complications, univariate and multivariate logistic regression models were used. Trial registration: ClinicalTrials.gov (NCT03029663). Registered 24 January 2017. RESULTS: Surgical complications were noticed in 228 (23.2%) patients, including 83 (8.4%) patients with more than one complication and 33 cases of Clavien-Dindo grade 3 complications (3.3%). The most common in-hospital complications were bleeding (n = 139, 14.1%) and bladder perforation (n = 46, 4.7%). In a multivariate analysis, nicotine use, high ASA score, and the presence of high-grade tumour were the most significant predictors of high-grade complications. The stage of the disease was the strongest predictor of bleeding, while the presence of muscle in the specimen and resident surgeon were the strongest predictors for bladder perforation. CONCLUSIONS: TURBT poses a significant risk of surgical complications, the majority of which are of low grade.
RESUMEN
INTRODUCTION: Preoperative identification of high-grade bladder cancer presence can optimize patient management. The aim of this study was to assess the association between preoperative pyuria and the pathological features of bladder cancer. MATERIAL AND METHODS: This retrospective analysis enrolled 943 patients undergoing transurethral resection of a bladder tumor. Patients were divided into two study groups based on the presence of pyuria in preoperative urine analysis, defined as the presence of >5 leukocytes in the high power field. Pyuria status as a potential predictive factor was then confronted with pathological features based on standard microscopic examination of the surgical specimen. RESULTS: Among 943 recruited patients, 294 (31.2%) presented with pyuria. Patients with pyuria were older (71 vs. 68 years, p <0.05), had higher rates of large (≥3 cm) tumors (37% vs. 26%, p <0.05), and more frequently presented concomitant hematuria (58% vs. 24%, p <0.05). In case of recurrent tumors patients with pyuria more often received intravesical chemotherapy in the past (4.8% vs. 1.4%, p <0.05). Regarding oncological data, patients with pyuria had significantly higher tumor stage and grade. On multivariable analysis pyuria was independently associated with high-grade tumors (OR 1.97, 95% CI 1.45-2.67). Specificity and negative predictive value of pyuria as a biomarker of high-grade tumors were 76% and 68%, respectively. CONCLUSIONS: Preoperative pyuria can be regarded as a predictor of the presence of high-grade bladder carcinoma in patients with bladder tumors.
RESUMEN
PURPOSE: The neutrophil-to-lymphocyte ratio (NLR), as an indicator of the systemic inflammatory response, predicts adverse outcomes in many malignancies. We investigated its prognostic significance in patients with non-metastatic renal cell carcinoma. MATERIALS AND METHODS: We retrospectively evaluated data of 196 consecutive non-metastatic RCC patients who underwent radical or partial nephrectomy between 2010 and 2012 at a single center. Overall survival (OS) was assessed using the Kaplan-Meier method and compared using the log-rank test. We applied univariate and multivariate Cox regression models to evaluate the prognostic value of dichotomized NLR for OS. Results: At a median follow up of 68 months, high NLR (? 2,69) correlated with worse survival outcome (P = .006 in log-rank test) and higher tumor stage (P = .035). Univariate and multivariate analysis identified elevated NLR (P = .039), as well as age (P = .002), high Fuhrmann grade (P = .002) and high pathologic T stage (P < .001), as significantly associated with overall survival. CONCLUSION: In our cohort, an elevated neutrophil-to-lymphocyte ratio is significantly associated with worse OS on univariate and multivariate analysis. Consequently, the NLR is an easily acquired biomarker, which may be useful in pretreatment patient risk stratification.

A potential reason for poor survival among patients with muscle-invasive bladder cancer (MIBC) in Poland is initial disqualification from curative treatment due to advanced stage of the disease or low performance status. The aim of this study was to describe patterns of care in patients with newly diagnosed MIBC. This is a multicentre retrospective cohort study involving 296 consecutive patients with primary histologically diagnosed MIBC. Therapeutic decisions and potentially underlying clinical factors were analysed. Full clinical data was available for 285 patients. One hundred and sixty-four (57.5%) patients were qualified for radical cystectomy (RC), 32 (11.2%) patients for a second step of transurethral resection of the bladder tumour (TURBT) intentionally followed by systemic chemotherapy, four (1.4%) patients after complete TURBT were qualified for adjuvant intravesical chemotherapy only, while the remaining 85 (29.8%) patients were qualified for palliative treatment in the form of chemotherapy and/or radiotherapy and/or best supportive care. Patients disqualified from curative treatment were older (78 vs. 69 years, p < 0.02), had lower BMI values (24.5 vs. 25.7 kg/m(2), p < 0.02), lower haemoglobin concentration (11.6 vs. 12.9 mg/l, p < 0.02), declared lower rate of nicotine abuse (50.5% vs. 72.1%, p < 0.02), and had a shorter time interval between first symptom and diagnosis (30 vs. 60 days, p = 0.02). As the majority of Polish patients with primary MIBC receive curative treatment, the stage of the disease alone seems not to be the leading cause of poor survival. However, appropriateness of qualification for RC and treatment quality needs to be assessed for final conclusion on the factors influencing outcomes of treatment in Poland.
RESUMEN
OBJECTIVES: To assess the interobserver variability of Clavien-Dindo scoring in urology. METHODS: A thematic survey was carried out simultaneously in nine Polish urological centers among 171 responders - 81 urologists and 90 urologists-in-training, made up of 16 women and 155 men. After Clavien-Dindo classification was presented, respondents were asked to grade nine typical urological complications according to Clavien-Dindo classification. Interobserver agreement, reproducibility of answers, as well as the influencing factors were analyzed. Questions in the survey related to complications of variable severity after basic urological operations, including four open, one laparoscopic and four endourological. RESULTS: Agreement on the grade of complication was moderate (κ = 0.45) and it was noticed in 69% of respondents (range 38-87%). No effect of surgical approach (classic vs endoscopic, 70% vs 67%, P = 0.64), or physician professional experience (resident vs urologist, 71% vs 66%, P = 0.77) was observed. The most significant discrepancies were found in cases of local complications after transurethral surgery (accordance in 39%) and laparoscopic radical prostatectomy (accordance in 55%), and in cases of severe general complications after Bricker operation (accordance in 58%). CONCLUSIONS: The variability of Clavien-Dindo classification scoring among urologists is significant. Thus, the Clavien-Dindo classification might require detailing before its eventual implementation in urology, together with appropriate training of specialists. However, despite some disadvantages, the simplicity, reproducibility and logical scheme of the Clavien-Dindo classification make it a promising tool for quality assessment in different fields of urology.
