Transurethral suturing of bladder following transurethral excision of female vesico-urachal diverticula: a novel technique with long-term follow-up results.

BACKGROUNDS: This study aims to describe and evaluate outcomes of transurethral surgery-natural orifice transluminal endoscopic surgery (TUS-Notes) technique in patients treated with transurethral excision of vesico-urachal diverticula (VD). METHODS: Patients who underwent TUS-Notes following transurethral VD excision due to recurrent urinary tract infection (rUTI) since 2013 were included in this prospective non-randomized cohort study. Under cystoscopic guidance VD and surrounding bladder wall was resected until the fatty tissue using monopolar resectoscope. The specimen was removed with a grasper through the cystoscope. TUS-Notes technique was performed with Minimal Suturing Device (MSD-Ney®). The needle of the suture was shaped according to suturing position and loaded into MSD-Ney. They were inserted into the bladder under cystoscopic guidance transurethrally. Once the defect was sutured properly, an extracorporeal knot was prepared and tied. The length of the operation (LOO), and perioperative complications according to the Clavien-Dindo grading system were noted. The integrity of the bladder was checked with cystography to assess objective cure. Subjective cure was evaluated with Patient Global Impression of Improvement (PGI-I) scale. RESULTS: The follow-up period of 65 participants varied from three months to eight years. The median LOO was 37 min. A Clavien grade-3 complication was observed in one patient. Peroperative failure was not noted. The median duration of hospital stays, and catheterization time was three days. Objective cure rate and subjective cure rates were 100%. UTI was not noted after surgery. CONCLUSIONS: Transurethral complete excision of VD is an acceptable technique to prevent rUTI. The TUS-Notes technique provides a successful minimal invasive treatment option for the treatment of bladder defects. CONCISE: Transurethral suturing of urinary bladder.

Identifying the predictors of estimated glomerular filtration rate after partial nephrectomy with a nonlinear regression model.

PURPOSE: To evaluate the effect of partial nephrectomy on renal function and to identify predictors of estimated glomerular filtration rate (eGFR) at 6 months after partial nephrectomy. METHODS: Medical data of 154 consecutive patients who underwent partial nephrectomy for a renal mass between January 2015 and March 2020 were retrospectively analysed. The primary outcome measure was eGFR at 6 months postoperatively. An ordinary least regression analysis using a restricted cubic spline for continuous variables was performed to examine the association between primary outcome measure and candidate predictors. RESULTS: Of the patients, 66 (42.9%) were females and 88 (57.1%) were males with a median age of 60 (range, 50 to 67) years. The median baseline eGFR was 90.40 (range, 74.96 to 102.97) mL/min/1.73 m2 , while the median eGFR at 6 months was 77.12 (range, 61.06 to 91.93) mL/min/1.73 m2 (P < .001). Baseline eGFR (regression coefficient (ß) = 22.7, 95%CI: 18.8 to 26.5, P < .001) was found to be most significant predictor with the postoperative eGFR levels at 6 months. In addition, advanced tumour size (ß = -3.17, 95%CI: -5.33 to -1.01, P < .001) and presence of hypertension (ß = -3.48, 95%CI: -6.96 to -0.003, P = .049) were also found to be inversely associated with the postoperative eGFR levels at 6 months. CONCLUSION: Baseline eGFR values, tumour size, and presence of hypertension are significant predictors of eGFR values in the mid-term in patients undergoing partial nephrectomy.

Change in Frequency and Predictors of Erectile Dysfunction With Changes in the International Index of Erectile Function-Erectile Function Domain Score in Patients With ST-Elevation Myocardial Infarction: A Prospective, Longitudinal Study.

BACKGROUND: Erectile dysfunction (ED) has been proposed as an early indicator for future coronary and peripheral vascular disease. AIM: We aimed to investigate the longitudinal change in proportion and predictors for ED with changes in erectile function domain (EFD) of the International Index of Erectile Function-15 (IIEF-15) in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PPCI). METHODS: Between December 2018 and June 2019, 286 male patients aged between 40 and 70 years who were treated with PPCI for STEMI were included. The patients were asked to complete the IIEF-EFD form 3 days after the procedure for the evaluation of baseline erectile functions. During follow-up 3 months after the index procedure, the patients were asked to refill the IIEF-EFD form. Both baseline and third-month IIEF-EFD scores were calculated, and the patients were classified into ED severity groups as per the IIEF-EFD scores. A linear mixed model was used to identify predictors of ED at 3 months. OUTCOMES: This study identifies the prevalence and predictors of ED with STEMI who underwent PPCI. RESULTS: The median age was 54 (range 48-61) years. The median IIEF-EFD scores at 3 days and 3 months were 25.5 (range 20.0-27.0) and 22.00 (range 18.25-25.00), respectively. Half of the patients were found to have ED with varying severity as per baseline IIEF-EFD scores. This rate increased to 79% at the 3-month follow-up visit. The IIEF-EFD scores of the patients decreased over time (P < .001). Advanced age (ß = -0.603, se = 0.192, P = .002), presence of three-vessel coronary artery disease (ß = -3.828, se = 0.783, P < .001), and diabetes (ß = -2.934, se = 0.685, P < .001) were found to be inversely associated with the IIEF-EFD scores. CLINICAL IMPLICATIONS: Advanced age, presence of three-vessel disease, and diabetes mellitus are the indicators of sexual rehabilitation needs in patients after STEMI. STRENGTHS & LIMITATIONS: This is the first study investigating the predictor variables for the development of ED after coronary artery disease treatment. The limitations include the lack of evaluation of anxiety and depression and the measurements of testosterone levels. CONCLUSION: The prevalence of ED was high among patients with coronary artery disease, and the frequency of ED increased during 3-month follow-up. Advanced age, three-vessel disease, and diabetes were significant predictors of ED with changes in IIEF-EFD score in patients with STEMI who underwent PPCI. Karabay E, Karsiyakali N, Cinier G, et al.

Relationship between plasma Atherogenic index and final pathology of Bosniak III-IV renal masses: a retrospective, single-center study.

BACKGROUND: There is an increased incidence of renal cell carcinoma (RCC) in patients with metabolic syndrome who usually have high levels of serum triglyceride (TG) and low high-density lipoprotein-cholesterol (HDL-C). Plasma atherogenic index (PAI) is the logarithmic ratio of serum TG level to HDL-C and related to cardiovascular diseases. In this study, we aimed to determine the accuracy of PAI in determining renal malignancy in localized renal masses preoperatively. METHODS: Totally 169 patients who were diagnosed with Bosniak III-IV lesions by imaging modalities and treated in our hospital with partial or radical nephrectomy were retrospectively analyzed using institutional renal cancer database between 2013 and 2018. Preoperative images were evaluated by two experienced radiologists. The patients were divided into two groups according to their postoperative pathological diagnosis as malignant or benign tumors. The PAI of each patient was calculated and the statistical significance of PAI in predicting malignancy for renal masses was analyzed using uni- and multivariable analyses. RESULTS: Of patients, 109 (64.5%) were males and 60 (35.5%) were females with a median age of 61 (33-84) years. Median tumor size was 6.5 (2-18) cm. Pathological diagnosis was malignant in 145 (85.8%) and benign in 24 (14.2%) patients. There was no statistically significant difference in serum TG levels between malignant and benign cases (p > 0.05). The HDL-C levels were significantly lower in malignant cases (p = 0.001). Median PAI value was 0.63 (0.34-1.58) and significantly higher in malignant cases (p = 0.003). The PAI cut-off value for malignancy was ≥0.34. The sensitivity was calculated as 88.2% and specificity as 45.8%, the positive predictive value as 90.8, negative predictive value as 39.3, and odds ratio as 6.37 (95% CI: 2.466-16.458). In multivariable analysis, gender, smoking status, and hypertension had no effect on malignancy, whereas PAI and HDL-C were independent risk factors (p = 0.003 and p = 0.003, respectively). The risk of malignancy was 5.019 times higher, when PAI was > 0.34 (95% CI: 1.744-14.445) in multivariable logistic regression analysis. CONCLUSIONS: The PAI can be used as a predictive tool in suspicion of malignant renal masses. In case of a benign pathology, PAI levels may be encouraging for surgeons for nephron-sparing surgery.

Evaluation of functional lower urinary tract dysfunction in children: are the physicians complying with the current guidelines?

OBJECTIVE: To elucidate whether the diagnostic and treatment approaches of the physicians for functional lower urinary tract dysfunction (LUTD) in children is complying with the current guidelines. MATERIAL AND METHODS: We have conducted an internet-based national survey for the physicians from different departments randomly sampled from the database of Turkish Paediatric Urology Society. Participants were asked to answer two-page questionnaire consisting of 4 main sections: "demography," "working conditions," "daily practice," and "scientific knowledge." Kruskal Wallis and multiple logistic regression were used for statistical analyses. RESULTS: Of the 117 departments a total of 93 have completed the survey (n: 58 urology; n: 35 paediatric nephrology). Routine use of a questionnaire with validated symptom scoring system was found to be 13.9%. Of the participants, only 38.7% were asking all of the patients to fill the bladder diary. During treatment, only 24.7% were applying standard urotherapy for every patient. Almost half of the clinicians (45.1%) believed that they were personally insufficient during the evaluation of those children. Finally, 86% reported that children with LUTD were not adequately approached. CONCLUSIONS: Evaluation of LUTD in children is not complying with the current guidelines. General approach for those children needs to be revisited by the clinicians.

Post-prostatic massage examination for prediction of asymptomatic prostatitis in needle biopsies: a prospective study.

PURPOSE: Although asymptomatic prostatitis is the most common noncancer diagnosis as demonstrated histologically by biopsies, screening and identification before biopsy remain unclear. In this study we prospectively evaluate the efficacy of examination of post-prostatic massage urine for prediction of asymptomatic prostatitis in biopsies. MATERIALS AND METHODS: A total of 161 consecutive men 50 to 80 years old with serum prostate specific antigen 4.1 to 10.0 ng/ml, normal digital rectal examination, no evidence of clinical prostatitis or urinary tract infection, who underwent 8 or 10-core prostate biopsies under transrectal ultrasonography guidance were included in the study. Immediate pre-biopsy leukocyte count in post-prostatic massage urine was determined per high power field (400 x). We selected 5, 7 and 10 leukocytes per high power field as cutoffs, and urine was examined for prediction of histological prostatitis. RESULTS: Histological diagnosis was prostatitis, benign prostatic hyperplasia and prostate cancer in 66 (41.0%), 63 (39.1%) and 32 (19.9%) patients, respectively. The mean number of leukocytes and percentage of positive post-prostatic massage urine microscopy for all cutoffs were significantly higher in subjects with prostatitis than in those without prostatitis (p <0.0001). Histological prostatitis was predicted most accurately by the 5 leukocyte cutoff (sensitivity 68.2%, specificity 82.1% and area under the receiver operating characteristics curve 0.75). CONCLUSIONS: In asymptomatic men with mild increases of prostate specific antigen histological evidence of prostatic inflammation is common. The leukocyte count in post-prostatic massage urine appears to be useful for screening of this condition before biopsy. Our data suggest that 10 leukocytes per high power field in post-prostatic massage urine, the usually applied cutoff, may be too high for the definition of prostatic inflammation.
