Filter by:This study will compare two techniques to minimize pain during and after penile surgery in children undergoing certain urologic surgeries. These two approaches include the caudal nerve block and the pudendal nerve block.
The aim of the study was to evaluate if application of a fibrin sealant over the urethroplasty suture line for waterproofing instead of a dartos vascularized pedicled flap to reduce complications and improve the outcome in hypospadias repair.
The goal of clinical trial is to compare in of analgesic efficacy of sacrale erector spinae plane block and caudal block in patients undergoing hypospadias surgery.We will include children between the ages of 6 months and 7 years in the 1st and 2nd categories in the ASA. In our study, we seek answers to the following questions: - Which of the sacral erector spinae plane block and caudal block applied to patients undergoing hypospadias surgery has higher postoperative analgesic efficiency than the other? - Which of the sacral erector spinae plane block and caudal block applied to patients undergoing hypospadias surgery is superior in duration of analgesia? After general anesthesia is administered to the participants, one of the 2 blocks will be administered in a randomized manner and the relevant data will be recorded.Our research will be conducted in a single center as a prospective randomized controlled study. It was planned to include 60 patients from the ASA I-II pediatric patient group aged between 6 months and 7 years, who will undergo hypospadias surgery in our hospital between December 2022-December 2023, and randomization will be done by closed envelope method. Two groups with sacral ESP and caudal block will be formed, each with 30 patients.
The goal of this observational study is to develop and validate a digital pattern recognition system based on artificial neural network to determine various parameters in hypospadias. The main question it aims to answer is: How accurate is the digital pattern recognition system based on artificial neural network to determine various parameters in hypospadias? Participants in this study are hypospadias patients aged < 18 years old. The guardian (and the patient, if applicable) will be informed about the study and asked for consent. The digital picture of participants' penis will be taken from different angles according to the predetermined angle. The clinical characteristics of the photographed penis are then inputted and used to train a customized artificial neural network (ANN). The machine is then used to predict various hypospadias parameters presenting at the patients' penis. The accuracy of the machine is then compared to the measurement done by pediatric urologists.
Hypospadias is a common congenital anomalies in male children affecting 1 in 200-300 male births, the penis urethral opening is found ventrally, penile curvature and a lack of foreskin (1). Multiple operations are described , Tubularised incised-plate is the preferred option for distal hypospadias and with trial to extend the operation indication to proximal and redo hypospadias (2). Its simple operative technique made TIP repair gain worldwide acceptance in addition to the low complication rate & good cosmetic outcome (3).It has several complication as stenosis meatus, fistula formation , uretheral stricture and failed repair (4). Objective scoring systems were introduced to allow better judgment and identification of the postoperative results, depending on pre-operative and intra-operative criteria (5). Modifications of the T.I.P operation was done to reduce complication and allow better results by using a graft , Snodgraft vs Snodgrass operation are nearly equal regarding the outcomes (6). To our knowledge there is no definite recommendation.
The purpose of this study is to assess the long term urinary, sexual, cosmetic and psycho-social outcomes of adult patients operated for hypospadias during childhood
to evaluate a modification to snodgrass technique in second layer closure of distal penile hypospadias
Evaluation of double faced transverse preputial onlay island flap for hypospadias repair in pediatrics. The preputial onlay island flap technique has been popularized for hypospadias repair as a result of offering a consistent combination of excellent cosmetic results and acceptable complication rates. Like other techniques, urethrocutaneous fistulae continue to be the most common complications, in addition to other complications, and can be attributed to the affection of flaps vascularity. Some authors describe a technique that resolves some of these problems by combining the unique benefits of the double-faced preputial flaps. This study aimed to evaluate double faced preputial onlay island flap technique for complication rate, outcomes for urinary stream, and cosmetic results.
To explore the optimal urethral coverage in hypospadias repair by comparing the success rate of both covering techniques: Dartos fascia versus Tunica Vaginalis flap.
The purpose of this trial is to assess the safety and efficacy of Holour in patients suffering from hypospadias treatment failure. Holour is intended for urethral replacement and is made from ex vivo expanded autologous oral mucosal cells including stem cells.
