RESUMEN

Introduction: This study aimed to determine whether sarcopenia is a predictor of overall survival (OS) and cancer-specific survival (CSS) in patients with bladder cancer (BC) undergoing radical cystectomy (RC). Material and methods: Patients who underwent radical cystectomy for BC between September 2016 and June 2022 were retrospectively reviewed. Patients underwent digital computed tomography (CT) scans of the abdomen and pelvis. The skeletal muscle index (SMI) was used to assess sarcopenia using CT images. OS and CSS were estimated using Kaplan-Meier curves. Predictors of CSS and OS were analysed using univariate and multivariate Cox regression models. Results: Of the 84 reviewed patients, 45 (53.6%) had sarcopenia. The median follow-up period for survivors was 70 months. Patients with sarcopenia were older and had a lower BMI, but other preoperative clinical and laboratory parameters were similar to those of patients without sarcopenia. During follow-up, 57 (67.9%) patients died, 39 (46.4%) due to BC. In addition, patients with sarcopenia had worse 5-year OS (24.4% vs 41.0%, p = 0.036) and CSS (35.6% vs 61.5%, p = 0.012) than non-sarcopenic patients. The findings indicate that sarcopenia is an independent predictor of increased CSS (HR, 2.841; p = 0.003) and overall mortality (HR, 2.465; p = 0.004) in multivariate analysis. Conclusions: The results of this study support the view that sarcopenia is an important risk factor for predicting CSS and OS in BC patients undergoing RC.

RESUMEN

OBJECTIVE: To determine the effectiveness of pelvis diameters in determining postoperative outcomes in men who underwent open radical cystectomy + urinary diversion, it is aimed to predict the factors that may affect the operative difficulty and possible surgical outcomes before the operation. METHODS: A total of 79 radical cystectomy patients operated in our institution with preoperative computed tomography (CT) were included the study. Pelvic dimensions; symphysis angle (SA), upper conjugate, lower conjugate, pelvic depth, apical depth (AD), interspinous distance (ISD), bone femoral width and soft tissue width were measured by preoperative CT. ISD index were defined as ISD/AD. Postoperative outcomes and indicators of operative difficulty were recorded. Regression analyses were used to predict perioperative and postoperative outcomes. RESULTS: Total of 96 complications were observed in 52 of the 79 patients in ninety days (65,8%) with a mean age of 68.25 years. There were significant correlations between SA and body mass index (BMI) with operative time (p = 0.006, p < 0.001; respectively). For estimated blood loss, there were significant correlations between preoperative hematocrit (p = 0,031). Analysis of multivariate logistic regression revealed that higher Charlson comorbidity index (CCI) and BMI were found to be significant predictors for major complications while CCI, pathological T stage and ISD index are prominent predictors for surgical margin positivity. CONCLUSIONS: Pelvic dimensions are not significant with minor or major complications. However, operative time may be associated with SA. Also, narrow and deep pelvis may increase the risk of positive surgical margins.

RESUMEN

INTRODUCTION: The objective of this study was to investigate the disease course after direct vision internal urethrotomy (DVIU) for short anterior urethral strictures. METHODS: We retrospectively analyzed 94 patients who underwent DVIU of the anterior urethra. Patients' age, etiology, length and localization of the strictures, total number of DVIU procedures, comorbidities, and other data were evaluated. RESULTS: The mean age of the patients was 67.2 years. The mean followup duration was 27.1 months. Recurrence was observed in 27.6% of the patients. Recurrence had occurred in these patients at a mean of 12 months. Both the comorbidity score (rs=0.395; p<0.001) and the urinary tract infection (UTI) score (rs=0.492; p<0.001) had significant correlation with the recurrence. In patients with recurrent urethral stricture, as the number of DVIU increased, the length and number of the urethral stricture increased as well. Patients with recurrence had a single stricture in the first DVIU procedure, while the number of strictures increased to a mean of two in the second and/or third DVIU procedures. CONCLUSION: DVIU is an effective treatment method in short anterior urethral stricture if it has been applied as a first intervention. However, if the stricture recurs, repeated DVIU application appears to be a negative predictive factor. The presence of perioperative treated UTI, smoking, and total number of comorbidities were negative predictive factors for the recurrence of urethral stricture. The disadvantages of our study is that it is retrospective, it includes a low number of patients, and the followup period is short.

RESUMEN

OBJECTIVE: The aim of this study was to present outcomes of our patients who had undergone retrograde intrarenal surgery (RIRS) with fluoroscopy-free technique and evaluate the efficacy and safety of the technique. MATERIAL AND METHODS: Between January 2013 and June 2015 the outcomes of 93 patients who had undergone RIRS with fluoroscopy-free technique were retrospectively evaluated. Our RIRS technique involved preoperative assessment of ureter by semi-rigid ureteroscope, inserting guidewire through semi-rigid ureteroscope, inserting ureteral access sheath over the guidewire with the visiual guidance of semi-rigid ureteroscope, passing flexible ureteroscope through the sheath, dusting the stone with holmium laser, rechecking the ureter with semi-rigid ureteroscope and inserting double J stent through semi-rigid ureteroscope. Low-dose computerized tomography scan was performed to all patients in postoperative first month and the results were classified as stone-free (absence of any fragment), clinically insignificant residual fragments (CIRF) (≤4 mm) and residual stone. RESULTS: Study population consisted of 62 (66.6%) male and 31 (33.3%) female patients with a mean age of 47.8±14 (range 14-93) years. Mean stone size was 14.7±5 (7-32) mm. Median operative time was 72 (30-125) minutes. Stone-free rate was achieved in 65 (69.9%) patients while CIRF was achieved in 13 (13.9%) and residual stones were detected in 15 (16.1%) patients. Five patients (5.37%) had minor complications, including hematuria and fever. No major complications were observed. CONCLUSION: Fluoroscopy-free technique is effective and safe technique in management of renal stone. Furthermore fluoroscopy-free technique can protect the surgeon from the negative effects of radiation.

RESUMEN

ABSTRACT Objective Recent studies have demonstrated the role of systemic inflammation in the development and progression of cancer. In this study, we evaluated whether preoperatively measured neutrophil-to-lymphocyte ratio (NLR) can predict lamina propria invasion in patients with non-muscle-invasive bladder cancer (NMIBC). Material and Methods We reviewed the medical records of 304 consecutive and newly diagnosed patients with bladder cancer who had been treated with transurethral resection between January 2008 and June 2014. In total, 271 patients were included in the study and the patients were divided into two groups according to the pathological stage (Group 1: Ta, Group 2: T1). NLR was calculated by dividing the absolute neutrophil count (N) by the absolute lymphocyte count (L). Results In total, 271 patients (27 women and 244 men) were enrolled. Mean age was higher in Group 2 than in Group 1 (67.3±10.8 vs. 62.9±10.8, p<0.001). Furthermore, the presence of high grade tumors and tumors ≥3cm in size was statistically higher in Group 2 than in Group 1 (70.9% vs. 9.9%, p=0.0001; 71.8% vs. 36%, p=0.0001, respectively). While the mean white blood cell (WBC) and N counts were statistically insignificant (7.63±1.87 vs. 7.69±1.93, p=0.780; 4.72±1.54 vs. 4.46±1.38, p=0.140; respectively), L was significantly lower and NLR was significantly higher in Group 2 than in Group 1 (2.07±0.75 vs. 2.4±0.87, p=0.001; 2.62±1.5 vs. 2.19±1.62, p=0.029; respectively). Conclusion Our data indicate that high NLR and low L are statistically associated with T1 stage, whereas low L are able to predict lamina propria invasion in patients with NMIBC. These findings suggest that pretreatment measurement of NLR may provide valuable information for the clinical management of patients with NMIBC. Prospective studies are now required to further validate the role of NLR as a risk factor in NMIBC.

RESUMEN

OBJECTIVE: The purpose of this study was to compare the 1-year results of patients on whom we used the transobturator tape method for the stress incontinence treatment according to body mass index (BMI). MATERIAL AND METHODS: Patients diagnosed with stress incontinence and treated with the transobturator tape method were divided into three groups according to BMI. We recorded the results of preoperative urodynamic studies; durations of operation, catheterization, and hospitalization; and complications of patients. Patients were evaluated 1 year after the operation with respect to the objective/subjective success rates of the operation, patient satisfaction rates, and possible late complications. RESULTS: The obese group was observed to have a significantly higher duration of operation than the normal and overweight groups (p<0.001). The objective and subjective success rates were not significantly different between the groups (p=0.567 and p=0.245, respectively). There was no statistical difference between the groups with respect to the satisfaction rates (p=0.245). There was no significant difference between all three groups with respect to both preoperative and postoperative complication rates (p=0.096). CONCLUSION: The transobturator tape method for stress incontinence treatment has similar objective and subjective success rates, independent of BMI. In the obese patients, the operation time is longer than the others, but there is no difference with respect to the complication rates.

RESUMEN

BACKGROUND/AIM: Studies suggest that trace elements may have an adverse impact on male reproduction, even at low levels. We tried to investigate the relationships between these metals and semen quality in various body fluids among men with infertility. MATERIALS AND METHODS: A total of 255 samples of blood, semen, and urine were collected from 85 men suffering from infertility. Inductively coupled plasma-optical emission spectrometry was used for the determination of 22 trace elements. We compared the results of the semen parameters with the results of the element determinations. RESULTS: Because of the high proportion of samples with values lower than the limit of detection for a number of the elements, only 8 of a total 22 trace elements were determined in the samples. When the concentrations of sperm were classified according to the World Health Organization's guidelines for normospermia, oligospermia, and azoospermia, statistically significant differences were found among Zn, Ca, Al, Cu, Mg, Se, and Sr concentrations in various serum, sperm, and urine samples (P < 0.05). CONCLUSION: In the present study, we found significant correlations between concentrations of Zn, Ca, Al, Cu, Mg, Se, and Sr and semen parameters in various body fluids.

RESUMEN

OBJECTIVES: The purpose of this study is to investigate the association of glycemic control prior to TUR-P and postoperative urethral stricture development. MATERIALS AND METHODS: Of the 168 patients with a diagnosis of urethral stricture, who underwent internal urethrotomy in our hospital were retrospectively analyzed for this study. 98 patients who underwent monopolar TUR-P in our hospital previously and were developed urethral stricture were divided into two groups as diabetic and nondiabetic. Based on their HbA1c concentrations, diabetics were allocated to two groups with good (HbA1c ≤6.5%) or poor (HbA1c > 6,5%) glycemic control. Time to internal urethrotomy and the other operative parameters were compared among groups. RESULTS: Time to internal urethrotomy after TUR-P was significantly shorter in diabetic patients with poor glycemic control than Group 1 and Group 2 (P = 0,02, P = 0,012) but no significant difference was found between Group 1 and Group 2 (P = 0,368). There was no significant difference in the mean diagnosed and resected prostate wight among groups There was no significant difference in the mean resection time and the mean time to urethral catheter removal among groups. CONCLUSIONS: Especially in poor glycemic control patients, urethral stricture development was seen in the early period after TUR-P. For this reason, in the elective TUR-P scheduled poor glycemic controlled patients the operation should be done after glycemic control.

RESUMEN

OBJECTIVE: In this study, we aimed to evaluate, the efficacy of surgical methods and the factors affecting the residual stone rate by scrutinizing retrospectively the patients who had undergone renal stone surgery. MATERIAL AND METHODS: Records of 109 cases of kidney stones who had been surgically treated between January 2010, and July 2013 were reviewed. Patients were divided into three groups in terms of surgical treatment; open stone surgery, percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS). Patients' history, physical examination, biochemical and radiological images and operative and postoperative data were recorded. RESULTS: The patients had undergone PNL (n=74; 67.9%), RIRS (n=22;20.2%), and open renal surgery (n=13; 11.9%). The mean and median ages of the patients were 46±9, 41 (21-75) and, 42 (23-67) years, respectively. The mean stone burden was 2.6±0.7 cm(2) in the PNL, 1.4±0.1 cm(2) in the RIRS, and 3.1±0.9 cm(2) in the open surgery groups. The mean operative times were 126±24 min in the PNL group, 72±12 min in the RIRS group and 82±22 min in the open surgery group. The duration of hospitalisation was 3.1±0.2 days, 1.2±0.3 days and 3.4±1.1 days respectively. While the RIRS group did not need blood transfusion, in the PNL group blood transfusions were given in the PNL (n=18), and open surgery (n=2) groups. Residual stones were detected in the PNL (n=22), open surgery (n=2), and RIRS (n=5) groups. CONCLUSION: PNL and RIRS have been seen as safe and effective methods in our self application too. However, it should not be forgotten that as a basical method, open surgery may be needed in cases of necessity.

RESUMEN

INTRODUCTION: Women suffer from depression more frequently than men, which indicates that sex hormones might be involved in the etiology of this disease. AIMS: The purpose of this study was to assess the relationship between testosterone and depression pathophysiology in depressive women along with sexual function. We also investigated whether antidepressant treatment causes any change in levels of this hormone or in sexual function. METHODS: Premenopausal female patients aged 25-46 years (n = 52) with diagnosed major depression were included in this study as the patient group, and 25- to 46-year-old premenopausal women without depression (n = 30) were included as the control group. MAIN OUTCOME MEASURES: Serum testosterone and sex hormone-binding globulin (SHBG) levels were measured twice, before and after the antidepressant treatment. Bioavailable testosterone (cBT) levels were calculated using the assay results for total testosterone (TT), SHBG, and albumin according to the formulas of Vermeulen et al. Depression severity was measured using the 17-item Hamilton Depression Rating Scale, and sexual function was evaluated with the Arizona Sexual Experience Scale. RESULTS: The mean TT and cBT levels significantly increased in the patient group after the antidepressant treatment (P < 0.001). Pre-treatment TT and cBT levels were significantly lower in the patient group than in the control group (P < 0.001). Similar results were obtained for post-treatment serum TT and cBT levels in the patient and control groups (P > 0.05). There were no significant differences among the groups in terms of SHBG level. CONCLUSION: The low testosterone levels in depressed women compared with women in the control group and the elevated levels post-pharmacotherapy suggest that testosterone may be involved in depression.

RESUMEN

A 46-year-old man was admitted with a scrotal long standing painless mass. The workup included physical examination, alpha-fetoprotein (αFP) and beta-human chorionic gonadotropin (ß-hCG) analyses, scrotal ultrasound, magnetic resonance imaging and urethrocystoscopy. Surgical exploration revealed a separate mass between the testes extending superiorly with a thin stalk. It was dissected easily to the anterior aspect of the seminal vesicles and removed from the junction to the seminal vesicles. Pathology reported an epidermoid cyst. To our knowledge this is the first case of a scrotal extratesticular epidermoid cyst attached to the seminal vesicles.

RESUMEN

A 78-year-old man was admitted to our urology polyclinic with painless penile mass. The lesion was 3.5 cm in size on the ventral aspect of the penis. He had been using a pad for urinary incontinance for 10 months and said that the lesion had been increasing in size for past 3 months. He underwent a wide local excision under local anesthesia. The histopathologic diagnosis was fibroepithelial polyp. A fibroepithelial polyp of the penis is very rare and strongly linked to long-term condom catheter use. We present a case of fibroepithelial polyp of the glans which is not associated with condom catheter use.

RESUMEN

Polyorchidism is an extremely rare testicular malformation in children, and its etiology is unknown. There is an increased risk for testicular malignancy in these patients and a common association with other abnormalities, such as cryptorchidism, inguinal hernia, testicular torsion, hydrocele, and varicocele. There are insufficient data in the literature on the ideal management of polyorchidism. We report a 14-year-old boy with polyorchidism and review the current literature regarding this anomaly. Physical examination revealed a discrete, painless, left intrascrotal lump. αFP, ß-hCG and LDH were normal. Scrotal ultrasound showed a well-circumscribed tissue in the left hemiscrotum measuring 2.5×2.0×1.3 cm and having the same echo-genicity as the normal testes. Color Doppler study and magnetic resonance imaging also confirmed the tissue as a third testis with its own epididymis draining to a common vas. The testis was left in situ, and the patient was managed conservatively. Polyorchidism should be considered in the differential diagnosis of all scrotal masses. The etiology of polyorchidism is thought to be accidental division of the genital ridge before 8 weeks of gestation. The cases are divided into two categories according to anatomical properties, such as having drainage to an epididymis and vas deferens. The majority of cases are mainly encountered during evaluation for the other symptoms associated. Recent evidence supports that these cases may be followed conservatively when clinical findings and imaging techniques detect no complications or suspicion for malignancy, torsion, hernia, or cryptorchidism.
