Objective:To explore the effect of systematic diagnosis and treatment model based on new classification on primary hypospadias.Methods:The data of 689 patients with primary hypospadias admitted to Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine from March 2010 to June 2021 were retrospectively analyzed. Of all, 349 cases from March 2010 to June 2016 were treated with traditional treatment methods, and 340 cases from July 2016 to June 2021 were treated with systematic diagnosis and treatment model based on new hypospadias classification. Traditional treatment group of patients according to the European Society of Urology (EAU) guide classification, were divided into the distal-anterior type (located on the glans or distal shaft of the penis), intermediate-middle type (penile) and proximal-posterior type (penoscrotal, scrotal, perineal). For distal type, tubularized incised plate (TIP) or dorsal inlay urethroplasty (Inlay) was performed. Patients with intermediate-middle type underwent Inlay, and patients with proximal-posterior type underwent Bracka staging. In the systematic diagnosis and treatment group, hypospadias was reclassified into distal type (located on the glan or in the first third of the shaft of the penis), junctional type (the back two-thirds of the shaft of the penis and the base of the penis), and proximal type (scrotum or perineum). For distal type, TIP or Inlay was used. Patients with junctional type were treated with urethroplasty with union free graft and local flap method (Montage). Patients with proximal type were treated with Montage or Bracka staging. Patients with testicular volume <0.8 ml and glans width <1.0 cm were treated with human chorionic gonadotropin (HCG) before surgery. There were 349 patients in the traditional group, with an average age of (18.58±7.59) months. There were 157 cases of distal-anterior type, 47 cases of intermediate-middle type and 145 cases of proximal-posterior type. There were 181 cases with penile curvature < 30° and 168 cases with penile curvature ≥30°. There were 340 cases in the systematic diagnosis and treatment group, with an average age of (18.94±6.05) months. According to EAU classification, 160 cases were distal-anterior type, 42 cases were intermediate-middle type and 138 cases were proximal-posterior type. There were 197 cases with penile curvature < 30° and 143 cases with penile curvature ≥30°. There was no significant difference in the above indicators between the two groups ( P>0.05). The surgical methods, incidence of postoperative complications and the time of hospital stay between the two groups compared. The changes in penis size and testis volume before and after the use of hormones in the systematic treatment group were compared. Results:In the traditional group, 139 patients underwent TIP, 65 patients underwent Inlay, and 145 patients underwent Bracka staging. In the systematic diagnosis and treatment group, 187 cases were reclassified as distal type (153 cases underwent TIP and 34 cases underwent Inlay). Of the 69 cases of junctional type, 10 cases underwent Inlay, and 59 cases underwent Montage. Of the 84 cases of proximal type, 77 cases underwent Montage, and 7 cases underwent Bracka staging. There was significant difference between the two groups ( P<0.01). In the traditional group, there were 31 cases of urinary fistula (8.9%), 43 cases of urethral stricture (12.3%), 21 cases of urethral diverticulum (6.1%), 45 cases of penile recurvature (12.9%), and the total incidence of complications was 40.1% (140/349). There were 19 cases of urinary fistula (5.6%), 28 cases of urethral stricture (8.2%), 15 cases of urethral diverticulum (4.4%) and 24 cases of penile recurvature (7.1%) in the systematic diagnosis and treatment group. The total incidence of complications was 25.3%(86/340). There were statistically significant differences in the incidence of the above complications between the two groups ( P<0.05). There was a significant difference in the duration of hospital stay between the traditional group and the systematic diagnosis and treatment group [(4.3±1.2) d vs. (1.5±0.5) d, P=0.01]. The width of glans penis after HCG treatment was (1.35±0.14) cm, which was significantly higher than that before HCG treatment [(0.96±0.24) cm, P=0.03]. The length of penis [(2.55±0.19) cm vs. (2.29±0.16) cm] and the volume of testis [(0.76±0.24) ml vs. (0.64±0.15) ml] were not significantly different from those before treatment ( P>0.05). Conclusions:The new classification has clarified the choice of surgical methods, avoiding the amplification of surgical indications. The systematic diagnosis and treatment model based on new classification has significantly improved the treatment effect of hypospadias and effectively reduced postoperative complications. It provides an optional diagnosis and treatment model for hypospadias.

Objective To evaluate if strategic urethrostomy could reduce complications in complicated hypospadias repair.Methods From January 2016 to August 2018,165 patients of complicated hypospadias were reviewed according to inclusion criteria.They were divided into three groups of one-stage repair (group A,n =86),two-stage repair using Bracka procedure (group B,n =49) and strategic urethrostomy (group C,n =30).The median age was 26 months in group A,24 months in group B and 28 months in group C.The median length of urethral defect was 3.0 (2.0-10.0) cm,4.0 (2.5-10.0) cm and 3.8(2.5-11.0) cm in the different three groups,respectively.No difference showed in age or length of urethral defect among 3 groups.Three groups were compared with rates of urethral fistula,urethral stricture and urethral diverticulum.Results After average of 20.0 months follow-up,the urethral stricture incidence of group C [3.3％ (1/30)] was significantly lower than that of group A [22.0％ (19/86),P =0.023] and group B[24.5％ (12/49),P =0.032].The complications were found in 7 patients with urethral fistula and 11 patients with urethral diverticulum in group A,4 patients with urethral fistula and 3 patients with urethral diverticulum in group B,none patient with urethral fistula nor urethral diverticulum in group C,respectively.The incidence of urethral fistula was 8.1％ (7/86),8.2％ (4/49) and 0 in the three groups,and the rate of urethral diverticulum was 12.8％ (11/86),6.1％ (3/49) and 0,respectively.None difference was shown neither in the incidence of urethral fistula nor urethral diverticulum among the three groups(P ＞ 0.05).Conclusions Strategic urethrostomy is a novel and effective method for complicated hypospadias repair.Application of strategic urethrostomy can significantly decrease urethral stricture and improve success rate in complicated hypospadias repair.

Objective To evaluate the complications and long-term efficacy of inside-out transobturator transvaginal tape ( TVT-O) for the treatment of stress urinary incontinence ( SUI) .Methods From January 2008 to December 2013,236 consecutive female patients (mean age 56 ±9 years,range 44-88 years)with the symptom of incontinence when abdominal pressure increasing (such as walking), underwent TVT-O operation.All these patients needed pads and were diagnosed with SUI by cough test and Marshall -bonny test before surgery , with the mean international consultation committee on incontinence questionnaire short form ( ICI-Q-SF) score of 15.6 ±3.9.Two grouping methods were used:the mid-term group including patients whose follow-up time was between 6 months and 3 years, the long-term group including patients whose follow-up time >3 years,the group of patients who underwent TVT-O only and the group of patients who underwent TVT-O plus pelvic floor repair at the same time . Their clinical and follow-up data , intraoperative and postoperative complications , subjective and objective effects were recorded and analyzed.Results Of these 236 patients,there were 1 case of bladder perforation (0.4%) and 1 case of intraoperative sling exposure to vagina ( 0.4%) .Postoperative complications included 36 ( 19.1%) groin/puncture point pain ,18 (9.5%) de novo frequency of micturition ,8 (4.2%) urinary retention /difficulty of urination.All the complications were relieved after symptomatic treatment or surgery except 2 cases of urinary retention/difficulty of urination.Their symptom kept existing after urethral dilatation and sling dissection and long-term intermittent self-catheterization was needed .One hundred and eighty-nine patients completed more than six months of follow-up, with mean follow-up time of ( 35.0 ±12.5 ) months.One hundred and sixteen (61.4%) cases was arranged to mid-term group and 73(38.6%) was arranged to long-term group.88.9%patients ( 168/189 ) were cured objectively and 9.5% patients ( 18/189 ) improved. There was also a significant subjective improvement ( ICI-Q-SF scores:15.6 ±3.9 preoperative versus 6.7 ± 2.3 postoperative,P0.05 ) . Patients who underwent TVT-O and those who underwent TVT-O +pelvic floor repair had no significant difference in efficacy (cured +improved rate 97.8%versus 100.0%,P>0.05).Conclusion TVT-O is a safe,effective and durable treatment for SUI , whether or not with concomitant procedure of pelvic floor repairment.
