RESUMO

OBJECTIVE: To evaluate the histopathologic correlation of recently described subclassification of Bosniak category 3 cysts (3s and 3n). MATERIALS AND METHODS: A total of 106 patients who underwent partial/radical nephrectomy due to a complex renal cyst (≥Bosniak 3) were retrospectively reviewed. All the scans of the patients were reevaluated by 2 experienced uroradiologists. Bosniak 3 cysts were reclassified as 3n (nodularity on the cyst wall/septae) and 3s (septated cysts without nodularity) as described in a recently published paper. Group 1 consisted of patients with Bosniak 3s, Group 2 consisted of patients with Bosniak 3n, and Group 3 consisted of patients with Bosniak 4 cysts. Three groups were compared according to patients' characteristics, radiological findings, histopathologic results, and survival outcomes. RESULTS: There were 52 patients in Bosniak 3 group and 54 patients in Bosniak 4 group. Mean follow-up was 35.3 months. Among Bosniak 3 cysts, 37 lesions were classified in 3s and 15 were classified in 3n. Malignancy was higher in 3n group than 3s (86.7% vs 54.1%, P= .026). Lesion size was significantly lower for malignant cysts compared to benign ones in the patients with Bosniak 3 lesions (44.2 ± 27.5 vs 80 ± 55.9 P= .005). In the subgroups, malignant lesions were significantly smaller than benign lesions in 3s group similar to general Bosniak 3 group. Most of the Bosniak 3 lesions were organ confined and low grade. CONCLUSION: The subclassification of Bosniak 3 cysts as 3s and 3n can help to differentiate highly suspicious malignant lesions from the relatively less suspicious ones.

RESUMO

OBJECTIVE: The aim of the present study was to evaluate the influence of preoperative hydronephrosis and ureteral orifice involvement (UOI) on survival of patients undergoing radical cystectomy (RC) for bladder cancer (BC). MATERIAL AND METHODS: A total of 162 patients with BC underwent RC between January 2006 and March 2017. Patients were divided into two groups for both presences of preoperative hydronephrosis and orifice involvement at final pathology. Additionally, tumors with orifice involvement were subgrouped histopathologically after RC as those with only UOI and those with invasive to the ureter with an additional concurrent site at final pathology. RESULTS: Preoperative hydronephrosis was detected in 57 patients. Preoperative and postoperative creatinine on month 3 were higher in the preoperative hydronephrosis (+) group (p<0.001). In addition, postoperative T stage, surgical margin positivity, invasion of urethra, and pathological upstaging were higher in this group. Cancer-specific survival (CSS) and overall survival (OS) were better in the hydronephrosis (-) group than in the hydronephrosis (+) group (p=0.001 and p=0.001, respectively). Preoperative hydronephrosis was found to be an independent factor in pathological upstaging. Patients were divided into two groups according to the presence of UOI. Group 1 consisted of patients without UOI, and group 2 with UOI. Preoperative hydronephrosis, hydronephrosis grade, and T stage were statistically higher in tumors with UOI. Moreover, CSS and OS were lower in group 2 than in group 1. CONCLUSION: Preoperative hydronephrosis and UOI are predicting factors on survival of patients undergoing RC for BC. Preoperative hydronephrosis was found to be an independent factor in pathological upstaging.

RESUMO

OBJECTIVE: To evaluate the effect of variant histology on pathological and survival findings in patients undergoing radical cystectomy due to muscle invasive bladder cancer. MATERIALS AND METHODS: Data from 146 patients with radical cystectomy performed due to muscle-invasive urothelial carcinoma between January 2006 to November 2016 at our clinic were investigated. The preoperative and postoperative data of patients with variant histology were compared with nonvariant urothelial carcinoma patients. Then of patients with variant histology only those with squamous differentiation (SqD) were compared with nonvariant urothelial carcinoma patients in terms of preoperative, postoperative and survival data. RESULTS: Of the 146 patients, 23 had carcinoma with variant histology. Of these, 17 had SqD, 4 had glandular differentiation, 1 patient had plasmocytoid variant and 1 patient had sarcomatoid variant. In patients with variant histology, postoperative T stage and upstaging was higher, with no difference observed in terms of overall and cancer-specific survival compared with nonvariant urothelial cancer patients. SqD patients were observed to have higher postoperative T stage compared to nonvariant urothelial cancer patients, with no significant difference observed in terms of survival. CONCLUSIONS: In cystectomy pathologies, patients with variant histology (especially SqD patients) were observed to have proportionally higher T stage compared to nonvariant urothelial carcinoma; however there were no significant differences for overall survival and cancer-specific survival.

RESUMO

PURPOSE: To investigate the utility of attenuation value (Hounsfield unit) of the filled bladder on computed tomography (CT) images and the association of these values with simultaneously obtained urine culture results. METHODS: Between January 2016 and December 2017, retrospective data of 58 patients who were admitted to the emergency department for various symptoms were examined. All patients were evaluated with urine dipstick microscopy, urine culture, and abdominal CT simultaneously. Group 1 consisted of patients with positive urine culture (n = 28) and Group 2 consisted of patients with negative urine culture (n = 30). The attenuation value of urine in the bladder at the level of the bladder trigone was measured inside an elliptical drawing covering all the urine inside the bladder excluding the bladder wall on axial non-contrast CT images. The predictive value of this calculated attenuation value for urine culture positivity was evaluated. RESULTS: The median attenuation value was - 6 (range - 17.8 to + 11) and 12 (range 0-32) in group 1 and group 2 (p < 0.001). According to cut-off value of - 1 attenuation value, sensitivity for predicting urine culture positivity was 92.9%, whereas specificity was 100% (AUC: 0.977 p < 0.001). Urine culture was positive in all of the 26 patients with attenuation value < - 1, whereas only two of the 32 patients with attenuation value > - 1 had urine culture positivity (p < 0.001 OR 14). CONCLUSION: The attenuation value of the urine in the defined area of the bladder may aid in the diagnosis of urinary infection with high sensitivity and specificity and without any additional cost.

RESUMO

PURPOSE: The purpose of the study was to investigate the predictive value of stone measurements by including a novel method on non-contrast computed tomography (NCCT) images for stone composition. METHODS: We retrospectively evaluated patients who had stone analysis, NCCT images, and underwent percutaneous nephrolithotomy between 2013 and 2016. Patient characteristics, stone measurements on NCCT images, and stone analysis results were evaluated. Hounsfield unit (HU) values (maximum (HUmax), minimum (HUmin), and average (HUave) of HU values) were investigated on NCCT images. HUdiff was calculated as the difference between the HUmax and the HUmin values. Patients were divided into seven stone groups and data were compared. Then patients were separately divided into two groups according to mineral complexity (mono-mineral and multi-mineral groups) and calcium-based (calcium and other stone groups) evaluation. RESULTS: In the study, 115 patients were evaluated. Age, gender, HUmin, HUmax, and HUave were significantly different between the stone groups. HUdiff and HUave were found to be 341.5 HU (AUC = 0.719, p = 0.017) and 1051.5 HU (AUC = 0.701, p = 0.029) as cut-off, respectively. Seventy of 72 > 341.5 HUdiff patients and 64 of 67 > 1051.5 HUave patients had multi-mineral stones (p = 0.001, OR 9.26, and p = 0.028, OR 4.27), respectively. In multivariate analysis, > 341.5 HUdiff rate was significantly higher in multi-mineral and calcium stone groups; HUave was also significantly higher in the calcium stone group. CONCLUSIONS: HUdiff and HUave were significant predictors of mineral complexity. HUdiff of < 341.5 HU showed 81.8% sensitivity and 67.2% specificity for identification of mono-mineral stones.

RESUMO

Intrauterine device (IUD) insertion is a long-acting and one of the most effective modes of reversible contraception. Complications that most commonly arise following IUD insertion are failed insertion, pain, vasovagal reactions, infection, menstrual abnormalities, and expulsion. In this paper, we present the case of a woman who experienced hydronephrosis due to the migration of IUD into the ureter after 30 years of insertion. To the best of our knowledge, this is the third such case reported in the literature.

RESUMO

The residual fragments in patients with preoperative and intraoperative culture positivity may serve as an infection focus. The aim of this study was to assess the importance of residual fragments for developing SIRS in patients with stone culture and/or RPUC positivity. After obtaining institutional review board approval, a total of 729 patients who undergone PCNL for renal stones were included in this study. Residual fragments accepted to be positive if any fragment was detected irrespective of size. All patients were followed-up postoperatively for SIRS criteria. The patients were then followed-up for residual stone-related events and infectious complications. 94 of the 729 patients have developed SIRS postoperatively. SIRS positivity was more common among males and found to be associated with higher stone burden and presence of staghorn stone. Patients with residual fragments after PCNL also had higher rates of SIRS. In the subgroup analysis of 203 patients who had post-PCNL residual fragments, the peroperative stone and/or RPUC positivity was not found to be associated with the development of the SIRS. Although presence of residual fragments after PCNL is associated with SIRS development, stone culture and/or RPUC positivity has no additional risk for development of post-PCNL infectious complications in patients with residual fragments.

RESUMO

Objective: The aim of this study is to examine the usefulness of preoperative neutrophile-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratios to predict pathological upstaging of invasive bladder cancer who underwent radical cystectomy. Material and methods: A total of 126 patients who underwent radical cystectomy at our clinic between January 2006 and March 2015 were retrospectively analysed. One hundred and twelve patients with organ-confined invasive bladder tumors (T2) detected at histopathological examination of transuretral resection material were included in the study. Upstaging was seen at histopathological examination of radical cystectomy specimens of 42 patients. We compared preoperative neutrophile-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio between upstaged and not-upstaged groups. Results: There were no statistically significant correlation between age, time to radical cystectomy, gender, lymphocyte-to-monocyte ratio, platelet-to-lymphocyte ratio ratios and carcinoma in situ in upstaged and non-upstaged groups. Statistical analyses showed that preoperative neutrophile-to-lymphocyte ratio was higher in upstaged patients (p=0.009). In multivariate analysis preoperative neutrophile-to-lymphocyte ratio and positive surgical margin were significantly higher in upstaged group. Conclusion: In organ-confined muscle invasive bladder cancer neutrophile-to-lymphocyte ratio seems to be an acceptable parameter to predict locally advanced disease.

RESUMO

The aim of this study was validation and comparison of stone scoring systems (S.T.O.N.E, GUY, CROES, S-ReSC) used to predict postoperative stone-free status and complications after percutaneous nephrolithotomy (PCNL) for staghorn stones. A total of 160 patients who had staghorn renal stones and underwent PCNL between January 2012 and August 2015 were included in the current retrospective study. Guy, S.T.O.N.E., S-ReSC (Seoul National University Renal Stone Complexity) and CROES (Clinical Research Office of the Endourological Society) nephrolithometry scores were calculated for each patient, and their potential association with stone-free status, operative and fluoroscopy time, and length of hospital stay (LOS) were evaluated. Postoperative complications were graded according to the modified Clavien classification, and the correlation of scoring systems with postoperative complications was also investigated. The mean CROES, S.T.O.N.E, Guy and S-ReSC scores were 143.5 ± 33.6, 9.7 ± 1.6, 3.5 ± 0.5 and 6.2 ± 2.0 respectively. The overall stone-free rate was 59%. All scoring systems were significantly correlated with stone-free status in univariate analysis. However, Guy and S-ReSC scores were the only significant independent predictor in multivariate analysis. And all four nomograms failed to predict complication rates. Current study demonstrated that Guy and S-ReSC scoring systems could effectively predict postoperative stone-free status for staghorn stones. However all four scoring systems failed to predict complication rates.

RESUMO

PURPOSE: We aimed to investigate the relationship between metabolic syndrome and sexual function and effective parameters on erectile dysfunction (ED). MATERIALS AND METHODS: A total of 1300 individuals were included in this study betwe¬en January 2009 and July 2012. All of individuals were asked to fill in an International Index for Erectile Function (IIEF) questionnaire. The presence of metabolic syndrome was determined when any three or more of the five risk factors were present according to the National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP)-III. Obese individuals were divided into six groups according to modified World Health Organization (WHO) definition. Effective parameters on erectile dysfunction were investigated in individuals with metabolic syndrome. RESULTS: Metabolic syndrome was detected in 455 individuals (35%). Mean domain scores of IIEF for all parameters were higher in individuals without metabolic syndrome than individuals with metabolic syndrome (p < 0.05). Mean domain scores of IIEF were lower in individuals with class 3 obesity than individuals with other obese groups (p < 0.05) for erectile dysfunction. There was statistical difference in terms of mean score of IIEF-Erectile function between smoking and nonsmoking groups (p < 0.05). Seventy percent of individuals with metabolic syndrome and 45% of individuals without metabolic syndrome had ED (p < 0.001). Logistic regression analysis revealed that waist circumference (WC) was the most important criteria for ED (p < 0.05). CONCLUSIONS: Metabolic syndrome, smoking and obesity seem to be potential risk factors for ED. We recommend individuals with metabolic syndrome, smoking and obesity should be questioned about ED.

RESUMO

OBJECTIVE: In this study, we aimed to investigate the relationship between age and tumor characteristics and to evaluate oncologic results after radical cystectomy in bladder cancer with respect to age. MATERIAL AND METHODS: We reviewed 460 patients retrospectively who underwent radical cystectomy. Patients were divided into two groups according to age: ≥70 (Group 1), and <70 (Group 2). We compared tumor pathological characteristics and the results of long-term follow-up in both groups. The first group included 76 (16.7%), and the second group 379 (83.3%) patients. The mean age of the patients was 73.3±3.01 years (70-85) in Group 1 and 58.3±7.47 years (34-69) in Group 2. The American Society of Anesthesiologists (ASA) score was less than three in all of the patients, and there was no risk for major surgery. RESULTS: No statistically significant difference was found between groups with respect to pathological T stage (p=0.567), lymph node involvement (p=0.179), or histological grade (p=0.567). Perioperative mortality rates were 3.9, and 3.4% in groups 1 and 2, respectively (p=0.218). Perioperative complication rates were 14.7, and 17.5% for groups 1, and 2 respectively (p=0.578). Five-year disease-specific survival (DSS) rates were 57.0, and 51.6% Groups 1, and 2, respectively. The mean DSS periods were 82.05±4.88 and 71.68±8.53 months for Groups 1, and 2, respectively. Five-year overall survival rates were 43.9% for Group 1 and 45.9% for Group 2. The mean overall survival times were 54.02±8.47, and 69.25±4.97 months for Groups 1, and 2, respectively. In Cox regression analysis, tumor stage (p=0.012) and lymph node involvement (p<0.001) were significant factors that affected the survival in both groups. None of the patients received neoadjuvant radiotherapy or chemotherapy. CONCLUSION: We found that oncological outcomes of radical cystectomy performed with the indication of bladder tumor were comparable between young and elderly. We believe that age per se should not constitute a contraindication for radical cystectomy operations.

RESUMO

Primary lymphoma of the prostate is a rare condition, representing 0.09% of prostatic malignancies. The clinical presentation of malignant lymphoma of the prostate is difficult to distinguish from other prostatic diseases. Systemic symptoms are rare. Treatments include surgery, chemotherapy and/or radiotherapy. We report a case of primary lymphoma of the prostate in a male patient who presented with lower urinary tract symptoms.

RESUMO

PURPOSE: We aimed to compare the effect and feasibility of a combined therapy with tamsulosin hydrochloride plus meloxicam, and tamsulosin hydrochloride alone in patients with benign prostate hyperplasia symptoms and impact on nocturia and sleep quality. MATERIALS AND METHODS: Four hundred male patients were included in this study between 2008 and 2011. Patients were randomly divided into two groups: one received tamsulosin hydrochloride 0.4 mg (Group 1, 200 patients) and the other tamsulosin hydrochloride 0.4 mg plus meloxicam 15 mg (Group 2, 200 patients) prospectively. Patients were evaluated for benign prostate hyperplasia (BPH) symptoms according to the American Urological Association clinical guidelines and sleep quality according to Pittsburgh Sleep Quality Index (PSQI). Patients were reevaluated after three months of treatment. The International Prostatic Symptom Score (IPSS), IPSS-Quality of Life (IPSS-QoL), maximal urinary flow rates (Qmax), average urinary flow rates (AFR), post void residual urine volumes (PVR), nocturia and Pittsburgh Sleep Quality Score (PSQS) were recorded at baseline and after three months. RESULTS: Mean age was 63.3 ± 6.6 and 61.4 ± 7.5 years in groups 1 and 2, respectively (p = 0.245). There were no statistically significant differences between both groups. Also, baseline prostate specific antigen (PSA), prostate volume, creatinine, International Prostatic Symptom Score (IPSS), IPSS-Quality of Life (IPSS-QoL), maximal urinary flow rates (Qmax), average urinary flow rates (AFR), post void residual urine volumes (PVR), nocturia and Pittsburgh Sleep Quality Score (PSQS) were similar in both groups. In addition, the total IPSS, IPSS-QoL, PVR, nocturia, and PSQS were significantly lower in Group 2 compared with Group 1 after treatment (p < 0.05). Qmax and AFR were higher significantly in Group 2 compared with Group 1 after treatment (p < 0.05). CONCLUSIONS: Cyclooxygenase (COX)-2 inhibitors in combination with an alpha blocker may decrease benign prostatic hyperplasia symptoms and increase sleep quality without serious side effects.
