The Penile Perception Score after distal hypospadias repair with tubularized incised plate and Mathieu

Objective: The aim of this study was to evaluate the Penile Perception Score (PPS) after repair of distal penile hypospadias using tabularized incised plate (TIP) and Mathieu procedures.Methods: A randomized controlled study was conducted at urology department from October 2013 to May 2014. It included 60 children who were divided into three groups: group A included 20 patients with distal hypospadias corrected using TIP; group B included 20 patients with distal hypospadias corrected using Mathieu; and group C included 20 children with normal male genitalia who were circumcised and considered as a control group.Results: There were no statistically significant differences between group A and group B in urologists’ and parents’ average sum of PPS evaluation, but urologists’ satisfaction was more than parents’ satisfaction. The PPS for TIP was 8.43 and 7.80 for urologists and parents, respectively. The difference was significant. The PPS for Mathieu were 8.04 and 7.89 for urologists and parents, respectively, with no significance. There were no statistically significant differences between group A and group B in the postoperative evaluation by urologists and by parents in meatus, glans, shaft skin, and general appearance. There were complications in 10% of cases from group A in the form of fistula, in 30% of cases from group B in the form of fistula in 25% and meatal stenosis in 5%, and no complication in group C.Conclusion: TIP showed better PPS score compared with Mathieu in hypospadias repair. However, the results of this study were not statistically significant. PPS was a good scale to evaluate hypospadias repair after surgery.Keywords: hypospadias, parents and urology, Penile Perception Scor

Reactive power control of three-phase low voltage system based on voltage to increase PV penetration levels

High penetration levels of distributed (PV) generation on electrical distribution system show many opportunities and challenges for Egyptian Distribution Utilities. The sovereign purposiveness of this threshing was to augment the penetration level of the PV power production in three-phase LV grids, by using solar inverters with reactive power control inconvertibility, imposed by certain grid codes. This method, which is based on the grid voltage profile for location – dependent PF set premium could be cushioned to whole solar inverter. The main target was to mitigate unnecessary Q absorption. This method combines two droop function power factor active power and Q-(V) strategies. The performance of each inverter is to compare the output voltage measured and control the quantity of Q. Therefore, improvement of the voltage profile at a certain bus can reduce the total losses, saving consumed power by customer and increase the system capacity by 4.5%.

Management strategy and outcomes of sacrococcygeal teratoma — an Egyptian multicenter experience

Abstract Objectives Nationwide criteria regarding patients with sacrococcygeal teratoma (SCT) are still lacking in Egypt. We aimed to present a multicenter study regarding the management and outcomes of this tumor to evaluate our national treatment strategy. Methods A retrospective analysis including all patients with SCT who were managed at four major Egyptian centers between 2013 and 2023. Clinical data, surgical approaches, and short- and long-term outcomes were discussed. Results The study included 95 patients (74 were females). Antenatal diagnosis was reported in 25% of patients. Seventy-one patients (74.7%) were classified as Altman type I/II. Surgery was performed via a perineal approach in 75 patients, whereas the remaining 20 underwent a combined abdominoperineal approach. Vertical elliptical incision with midline closure was conducted in 51.5% of patients, followed by classic or modified chevron incisions. Benign mature teratoma was detected in 82% of patients. At a median follow-up of 57 months, eight patients (8.5%) had relapsed. The 5-year overall survival (OS) and event-free survival (EFS) of all patients were 94% and 91%, respectively. In the after-care monitoring, 19 patients (20%) had urinary or bowel dysfunctions. Nine of them were managed using medications. Clean intermittent catheterization was practiced in another five patients. The remaining five underwent further surgical interventions. Conclusion Favorable outcomes were achieved in our country during the last decade. Diverse perineal incisions were performed for resection, and vertical elliptical with midline closure was the commonest. During follow-up, 20% of patients developed urological or bowel dysfunctions that required medical and surgical treatment modalities to improve their quality of life
