Background: About one in 200 to one in 300 male births has hypospadias. The prevalence of this congenital anomaly varies worldwide. The meatus is located distally in approximately 70% of cases. Several surgical techniques were described for distal hypospadias repair; despite this, there is no ideal approach. This study compares urethral advancement &glanuloplasty, and TIP techniques in terms of feasibility, duration of operation, and complications. Patients and., Methods: This prospective randomized comparative study was conducted at Al-Azhar University Hospitals from April 2022 to October 2022. Fifty-seven cases with different types of hypospadias were assessed for eligibility. Among them, seven cases were excluded due to the presence of severe chordee (n = 3), proximal variant (n = 2), and recurrent cases of hypospadias (n = 2). Fifty cases were randomly divided into two groups using a 1:1 ratio (computer-generated randomization). Twenty-five cases were subjected to urethral advancement and glanuloplasty, and the rest were subjected to tubularized incised plate (TIP) urethroplasty., Results: The mean age of all studied cases was 4.2 years. Approximately 52% had coronal or sub-coronal meatus, whereas 48% had glandular meatus. Both groups were matched according to age and meatus location (p > 0.05). No statistically significant difference was observed between the two groups regarding duration of operation, postoperative pain, and postoperative hospital stay. In addition, both groups did not differ significantly in late complications (meatal stenosis, meatal retraction, fistula, and glans dehiscence)., Conclusions: Both urethral advancement &glanuloplasty, and TIP urethroplasty have comparable short-term outcomes. Urethral advancement and glanuloplasty is preferred in certain conditions, especially in circumcised children or those with a narrow urethral plate., Trial Registration: The study protocol was approved by the Pan African Clinical Trials Registry (number for the registry is: PACTR202211757905870) on (29/11/2022). All procedures were performed per the Helsinki Declaration., (© 2023. The Author(s).)

Objectives: To evaluate the role of preoperative UWT in the prediction of impaction of ureteral stones stratified according to stone size in ureteroscopic laser lithotripsy., Patient and Methods: This study included 154 patients submitted to URSL for ureteral stones. Radiological data comprised the presence of hydronephrosis, anteroposterior pelvic diameter (PAPD), proximal ureteric diameter (PUD), and maximum UWT at the stone site. Collected stone characteristics were stone size, side, number, site, and density., Results: The study included 154 patients subjected to URSL. They comprised 74 patients (48.1%) with impacted stones and 80 (51.9%) with non-impacted stones. Patients were stratified into those with stone size ≤ 10 mm and others with stone size > 10 mm. In the former group, we found that stone impaction was significantly associated with higher PAPD, PUD, and UWT. In patients with stone size > 10 mm, stone impaction was related to higher UWT, more stone number, and higher frequency of stones located in the lower ureter. ROC curve analysis revealed good power of UWT in discrimination of stone impaction in all patients [AUC (95% CI) 0.65 (0.55-0.74)] at a cut-off of 3.8 mm, in patients with stone size ≤ 10 mm [AUC (95% CI) 0.76 (0.61-0.91)] at a cut-off of 4.1 mm and in patients with stone size > 10 mm [AUC (95% CI) 0.72 (0.62-0.83)] at a cut-off of 3.0 mm., Conclusions: Stratifying ureteric stones according to size would render UWT a more practical and clinically-oriented approach for the preoperative prediction of stone impaction., (© 2023.
