Objective: To investigate and compare the effects on pain of intraurethral 2% lidocaine gel and plain lubricating gel in male patients underwent flexible cystoscopy. Material and methods: The data of 220 male patients who underwent flexible cystoscopy between March 2012 and August 2014 were retrospectively analized. The patients were divided into 2 groups according to using intraurethral gel types. Group I included 120 patients who were underwent flexible cystoscopy with 2% lidocaine gel and Group II was consisted from 100 patients who underwent flexible cystoscopy with plain lubricating gel. The groups were compared according to postprocedure data including pain score, procedure time and age of patients. Results: The mean age of the patients in Group I was 50.02±11.87 years while that in Group II was 52.03±13.37 years (p=0.492). The mean procedure times were 6.02±0.787 and 6.28±0.689 minutes in Group I and Group II respectively (p=0.061). Pain perception scores were not statistically different between the groups (Group I: 3.10±0.980, Group II: 3.34±0.789, p=0.132). Conclusion: Use of intraurethral 2% lidocaine gel has no advantage over plain lubricating gel in regard to pain control during flexible cystoscopy in men.

To find the machine learning (ML) method that has the highest accuracy in predicting the semen quality of men based on basic questionnaire data about lifestyle behavior. The medical records of men whose semen was analyzed for any reason were collected. Those who had data about their lifestyle behaviors were included in the study. All semen analyses of the men included were evaluated according to the WHO 2021 guideline. All semen analyses were categorized as normozoospermia, oligozoospermia, teratozoospermia, and asthenozoospermia. The Extra Trees Classifier, Average (AVG) Blender, Light Gradient Boosting Machine (LGBM) Classifier, eXtreme Gradient Boosting (XGB) Classifier, Logistic Regression, and Random Forest Classifier techniques were used as ML algorithms. Seven hundred thirty-four men who met the inclusion criteria and had data about lifestyle behavior were included in the study. 356 men (48.5%) had abnormal semen results, 204 (27.7%) showed the presence of oligozoospermia, 193 (26.2%) asthenozoospermia, and 265 (36.1%) teratozoospermia according to the WHO 2021. The AVG Blender model had the highest accuracy and AUC for predicting normozoospermia and teratozoospermia. The Extra Trees Classifier and Random Forest Classifier models achieved the best performance for predicting oligozoospermia and asthenozoospermia, respectively. The ML models have the potential to predict semen quality based on lifestyles.

Objective: To evaluate the effect of glanular and urethral catheter fixation to the abdominal skin on wound dehiscence. Material and methods: After a standard tubularized incised plate urethroplasty (TIPU) for hypospadias repair, 128 patients were divided into two groups based on glanular and urethral catheter fixation to the abdominal skin as follows: no glanular and urethral catheter fixation (Group A) and glanular and urethral catheter fixation (Group B). Groups A and B included 61 and 67 patients, respectively. Results: No significant difference was determined between the groups with respect to age, meatal localization, and length of hospital stay. Wound dehiscence was noted in 13.1% and 2.9% patients in Groups A and B, respectively, after surgery (p=0.029, odds ratio=4.9). Patients in Group B had no excessive analgesic usage and unpleasant scarring due to the glans suture. Conclusion: Glanular and urethral catheter fixation to the lower abdominal skin considerably reduced wound dehiscence after hypospadias repair.
