Issi Y, Bilir C
Turkish journal of urology. 2022;48(2):150-154
Abstract
BACKGROUND The benefits of preparing the dorsal dartos flap before urethroplasty were investigated. MATERIALS AND METHODS Patients with coronal, subcoronal, and distal penile hypopadias without severe cordee who underwent surgical repair between October 2016 and September 2020 were included in the study. Tubularized incised plate urethroplasty technique was applied to all patients. The patients were divided into two groups: In Group 1, the dorsal dartos flap was prepared after urethroplasty, which is the commonly used technique today, and sutured on the neourethra. In Group 2, the dorsal dartos flap was prepared before the post-degloving urethroplasty. The amount of bleeding, the duration of the surgery, and the complications between the two groups were recorded and compared. RESULTS Twenty-two patients who could be followed up for at least 3 months were examined. There were 10 patients in Group 1 and 12 patients in Group 2. A statistically significant difference was found between the amount of bleeding of the operation in the two groups. Duration of operation, hematoma, infection, skin necrosis, or glanular dehiscence were not observed in any patient. CONCLUSIONS Preparing the dorsal dartos flap, before urethroplasty significantly reduces the amount of bleeding. This may be a new modification alternative in hypospadias surgery.

Journal of pediatric urology. 2020
Abstract
BACKGROUND Hemostasis aimed to maintain the bloodless surgical field for better exposure for the surgeon. There are no trials regarding the impact of hemostasis techniques for hypospadias surgery on surgeon satisfaction and patients' reported outcomes. Application of penile tourniquet is a common practice in hypospadias surgery that aims at reducing blood loss and improving visualization. Yet, scarce data exist on the effect of penile tourniquet on hypospadias repair outcomes. PURPOSE To evaluate the safety and efficacy of restraining penile perfusion using a tourniquet in hypospadias repair on the surgical outcome, also surgeons and patients reported outcomes. To evaluate the effect of penile tourniquet application on hypospadias repair outcome and surgeon's satisfaction with intraoperative hemostasis. STUDY DESIGN In this single-blinded randomized controlled trial, a total of 110 children with distal hypospadias amenable for TIP repair were assigned to hypospadias repair with or without intraoperative application of a penile tourniquet. Surgeries were performed by a junior (2-5 years of experience in TIP repair) or a senior pediatric urologist (with >5 years of experience). Intraoperative blood loss, the number of times bipolar diathermy was used, hemoglobin deficit, and operative time were compared. Surgeon's satisfaction with intraoperative hemostasis was evaluated using a 4-tiered questionnaire. Patients were followed up for a minimum of one year. Complications and readmission rates were compared. The patient-reported outcome of hypospadias repair was assessed using the hypospadias objective scoring evaluation (HOSE). RESULTS Baseline patient demographics and hypospadias characteristics were comparable between the study groups. Bipolar diathermy was more often used in the non-tourniquet group (mean ± SD = 5.7 ± 1.8 times vs. 6.7 ± 1.9 for the tourniquet group; p = 0.007). Also, the operative time was longer in non-tourniquet group [mean = 54.7 ± 14.9 vs. 60.8 ± 12.5 min (p = 0.028)]. Junior surgeons were more likely to be satisfied with hemostasis when a tourniquet was used (97.4% vs. 79.5%, p = 0.02). Postoperative complications, readmission rates, and patient-reported outcomes were similar between both groups. CONCLUSION The application of penile tourniquet during hypospadias repair can reduce operative time and the need for diathermy use; and also improves junior surgeon's satisfaction with intraoperative hemostasis without adversely affecting success rates or patient-reported outcomes.

Journal of Pediatric Urology. 2018;14((5):):420 e1-420 e5
Abstract
BACKGROUND Intraoperative blood loss is considered to be an important issue in hypospadias surgery. Some studies have demonstrated the utility of caudal epidural block (CEB) in this regard among pediatric patients with hypospadias. Though there is evidence in favor of the use of CEB as the only anesthetic method for pediatric surgeries, it is usually used in combination with general anesthesia. In this form of use, it could have more favorable outcomes for both intra- and postoperative periods. There are few studies regarding the effectiveness of CEB on intraoperative blood loss. OBJECTIVE We aimed to evaluate the utility of CEB on blood loss, operation time, and analgesic use during hypospadias repairs of pediatric population referred to our university hospitals. STUDY DESIGN In this randomized clinical trial, consecutive patients with hypospadias who were candidate for surgery were enrolled and randomly allocated to one of the two groups: group A received caudal epidural block (CEB) plus general anesthesia (GA) before surgery and group B received only GA. Intraoperative blood loss, operation time, and dose of fentanyl used during the procedure were recorded and compared. All surgeries were performed by a single pediatric urologist in two different university hospitals that was not blinded to the study groups. RESULTS In this study, 57 pediatric patients with hypospadias who underwent surgical repair were studied, from which 29 and 28 patients were allocated to receive or not to receive preoperative CEB, respectively. The patients' age, weight, ASA, score and severity of hypospadias were not significantly different between the two groups. The operation time was significantly lower in the CEB before surgery group (p < 0.05). The mean dose of fentanyl and volume of blood loss during procedure were lower in the CEB group, although for fentanyl it approached but did not reach statistical significance. CONCLUSION The findings of current study indicated that caudal epidural anesthesia in addition to general anesthesia has a favorable effect on reducing blood loss during operation, operation time, and analgesic use. Our data confirm the findings of previous studies in this field. Further studies are recommended to evaluate the effect of this type of analgesia in other outcomes of hypospadias repair surgery. Our results could be used for revising existing surgical guidelines for better management of hypospadias.

Alizadeh F, Fakoor A, Haghdani S
Journal of pediatric urology. 2016;12((3)):160.e1-5.
Abstract
OBJECTIVE To compare tourniquet application and epinephrine injection for hemostasis during hypospadias surgery in terms of bleeding and complications. METHODS Between April 2013 and September 2014, patients who were admitted for hypospadias repair were divided by random allocation into either a diluted epinephrine injection (DE) group or tourniquet application (T) group for hemostasis during the procedure. In the T group, a rubber band was applied at the base of the penis after skin dissection, and in the DE group, epinephrine 1/100,000 was injected along the incision lines. The patients' ages, urethral defect lengths, pre-operative, intraoperative and postoperative variables were compared between the two groups. RESULTS A total of 70 patients (35 in each group) were enrolled into the study. The mean ages and preoperative variables were not significantly different. Average blood loss was 23.51 +/- 15.36 cc in the tourniquet group and 15.99 +/- 10.00 cc in the epinephrine group, and was significantly higher in tourniquet group (P = 0.022); however, the mean operative time was not significantly different. Postoperative complications, described as Clavian classification, were reported in eight patients (23%) in the T group and 10 patients (30%) in the DE group, which was not significantly different. CONCLUSION Epinephrine injections minimize operative bleeding without significant harmful effects on postoperative outcomes; therefore, it could be considered to be a safe and effective method for preparation of a bloodless field during hypospadias surgery.Copyright © 2016 Journal of Pediatric Urology Company.

African Journal of Paediatric Surgery:AJPS. 2014;11((3)):215-8.
Abstract
BACKGROUND A comparative study of topical feracrylum citrate versus adrenaline to minimise haemorrhage-related complications in paediatric hypospadiac patients. PATIENTS AND METHODS A total of 108 consecutive paediatric hypospadiac patients (48 in the study group and 60 control - random allocation) were studied. In the study group, 1% feracrylum citrate solution was used and adrenaline (1:100,000) in controls. RESULTS Among the study group, average number of blood-soaked gauge pieces were 2.95/patient, correlating with average intraoperative blood loss of 14.74 ml. In controls, average blood-soaked gauge pieces were 4.83/patient corresponding to an average blood loss of 24.13 ml. The average amount of blood loss during surgery in the <5 years was 13.70 ml/patient in the feracrylum group, while the same in the adrenaline group was 23.45 ml. Average duration of surgery was 79 min in the study group, while the same in controls was 94 min/patient. Average number of cauterisations was 0.255/patient in the study group and 0.583/patient among controls. Postoperative haematoma was seen in 8% study group compared with 18% controls. Wound oedema appeared in 4.17% study group and 11.67% controls. Postoperative complications were higher among controls. CONCLUSIONS Feracrylum is more efficient and safer topical haemostatic agent than adrenaline. It reduced the frequency of cauterisation and tissue damage, intraoperative blood loss, and postoperative complications. RN 0 (Vasoconstrictor Agents). 2968PHW8QP (Citric Acid).

Journal of Pediatric Surgery. 2008;43((10):):1869-72.
Abstract
UNLABELLED Urethrocutaneous fistula is one of the most common complications after hypospadias surgery. The incidence of fistula development has varied from 4% to 20% in larger series. We sought to investigate the role of fibrin glue (Tisseel manufactured by Baxter India Pvt Ltd, Chennai, India) to reduce the chances of fistula formation in cases in proximal penile hypospadias. METHOD A total of 120 patients with proximal penile hypospadias (patients having urethral meatus at posterior third of penile shaft and at penoscrotal junction) were included in the present study. Patients were randomly allocated into 2 groups of 60 each by using Strata 9 software random number table. In group A, fibrin glue was used as a sealant after hypospadias surgery, whereas in group B, no sealant was used. All the operations were performed by single surgeon using transverse preputial tubularized island flap urethroplasty. RESULT Fistula formation occurred in 6 cases in group A (10%) and 19 cases in group B (32%) (P = . 027). The fistulae observed in fibrin glue group A were single and small in size (<1 mm). Multiple (>or=2 fistulae) and larger fistulae (>2 mm) were observed in group B. Overall complication was significantly higher in group B (P = . 006). CONCLUSION Fibrin glue in hypospadias repair does not eliminate fistula formation. However, it seems that it minimizes the incidence of fistula formation.
