To evaluate and compare the outcomes and complications of three different surgical techniques for treating primary proximal hypospadias with ventral curvature(VC)≥30°,we retrospectively reviewed the medical records of patients who underwent primary repair of proximal hypospadias with vC≥30°after degloving at Beijing Children's Hospital Affiliated to Capital Medical University(Beijing,China)from January 2019 to January 2021.A total of 152 patients were divided into three groups:transverse preputial island flap(TPIF)combined with Duplay,modified Koyanagi,and staged TPIF,which were performed on 55,16,and 81 patients,respectively.A total of 39(25.7%)patients had *** rates were similar for the TPIF combined with the Duplay group(40.0%)and modified Koyanagi group(50.0%)but lower for the staged TPIF group(11.1%;P<0.01).The incidence of urethrocutaneous fistulas was significantly higher in TPIF combined with Duplay group(21.8%)compared to staged TPIF group(4.9%;P=0.01).In univariate analysis,the length of the urethral defect was the single factor that could predict complications;the cutoff was 4.55 *** patients in the long urethral defect group than in the short one had complications(34.1%vs 15.7%,P=O.O1).These results indicate that staged TPIF produced a better outcome,whereas more patients in the TPIF combined with Duplay group presented with two or more complications.

Objective To explore the effectiveness of renal denervation (RDN) on blood pressure with the appropriate dosage of phenol/ethanol solution in spontaneously hypertensive rats (SHRs). Methods RDN was performed on the bilateral renal artery. Forty SHRs were divided into four groups according on the dosage of phenol (10% phenol in absolute ethanol): sham group, 0.5 mL phenol group, 1 mL phenol group and 1.5 mL phenol group (n = 10 in each group). Blood pressure was measured by tail-cuff plethysmography. Plasma creatinine was determined four weeks after the treatment. The kidneys and renal arteries were collected and processed for histological examination. Results A sustained decrease in systolic blood pressure (SBP) was only observed after the application of 1 mL phenol for four weeks, while SBP was lowered during the first week after RDN and increased in the following three weeks in the 0.5 mL and 1.5 mL phenol groups compared with the sham group. Renal norepinephrine (NE) was significantly decreased four weeks after RDN in the 1 mL and 1.5 mL phenol group compared with the sham group, but not in the 0.5 ml group. RDN with 1 mL phenol obviously reduced glomerular fibrosis. Histopathological analysis showed that tyrosine hydroxylase immunoreactivity was lower in the 1 mL and 1.5 mL phenol groups compared with the sham group. Moderate renal artery damage occurred in the 1.5 mL phenol group. Conclusion Chemical denervation with 1 ml phenol (10% phenol in absolute ethanol) effectively and safely damaged peripheral renal sympathetic nerves and contributed to the sustained reduction of blood pressure in SHRs.
