Multiple dorsal midline plication (MDMP) for correction of Donnahoo type Ⅲ chordee in postpubertal patient / 中华泌尿外科杂志

Objective To evaluate the role of multiple dorsal midline plication (MDMP) procedure in correction of Donnahoo type Ⅲ chordee in postpubertal patient.Methods From September 2010 to July 2013,33 postpubertal patients with Donnahoo type Ⅲ chordee (＞ 20°) were treated with MDMP procedure.The age ranged from 18 to 37 years with an average of 29 years.Primary surgery was indicated in 18 patients including type Ⅲ chordee in 11 and type Ⅲ/Ⅳ in 7,with associated hypospadias in 12.Redo surgery was warranted in 15 patients including type Ⅲ chordee in 13 and type Ⅲ/Ⅳ in 2,with associated urethral defects necessitating repair in 12.Intraoperative artificial erection was induced to confirm the degree and length of chordee.Longitudinal plication sutures,4 dots each,were applied close to the midline in a parallel fashion on each apex of curvature,to achieve satisfactory orthoplasty with 16-dot to 64-dot plication according to the chordee status,and the urethral repair indicated was achieved simultaneously.Results Satisfactory orthoplasty was achieved with 16-dot plication in 16 patients,24-dot in 10,32-dot in 6,and 64-dot in 1 patient whose penile curvature was severe and long.Followup was obtained from 35 to 69 months with an average of 46 months.Three patients lost of followup.Urethroplasty-related complications were noted in 5 patients including urethrocutaneous fistula in 2,urethral dehiscence in 1,urethral diverticulum in 1,and urethral stricture in 1.Mild cicatrical curvature (less than 15 degree) was noted in 2 patients.No postoperative priapism,erectile dysfunction,and paraesthesia was noted,nor chordee recurrence.Conclusions When applied appropriately,MDMP is an effective procedure in correction of Donnahoo type Ⅲ chordee in postpubertal patient with good and long-standing orthoplasty.

Surgical diagnosis and correction of chordee among hypospadias / 中华泌尿外科杂志

ObjectiveTo explore the importance and significance of classification diagnosis and treatment of chordee among hypospadias in children.MethodsA random sample review and controlled study was made in patients with hypospadias and chordee from 1989 to 2011 in First Affiliated Hospital of Sun Yat-Sen University,and the patients were divided into 2 groups.There were 232 cases in group A,who were all diagnosed as chordee only on the basis of clinical symptoms or an erection induced by artificial stimulation before operation.All the 232 cases were corrected empirically without objective assessment by degloving the penis,dissecting superficial and deep fascia,and cutting off the urethral plate,and so on during operation.There were 25 cases in group B,who were all strictly implemented on classification diagnosis and treatment of chordee,in sponge saline injection test during operation and correction effect evaluation after operation.Chordee was classified according to different etiology and pathology:skin type,fascia-type,urethra type,sponge type and the glans of penis type.There were different operating methods in different ways of folding tunica albuginea.ResultsIn group A,86 patients (37％) had postoperative recurrence of chordee,25 patients ( 11％ ) had pain during erection after surgery,183 patients were satisfied with correction of chordee (79％).In group A,25 patients were in their adulthood when followed up,and 7 patients had IIEF-5 score ＜21 points.In group B,the single type of chordee among hypospadias were 7/25 (28％),merged type were 18/25 (72％).All patients were followed up without chordee recurrence or painless erection,and 100％ patients or families were satisfied with correction of chordee.The efficacy difference were statistically significant between the two groups in chordee correction.In folding tunica albuginea group in group B,the penile erection length was (4.58 ± 1.59) cm before the correction,and (6.16 ±2.54) cm after correction.In non-folding tunica albuginea group,penile erection length was (4.O1 ± 1.18 ) cm before correction,and (5.82 ± 1.51 ) cm after correction.The difference was not significant between the 2 groups in penile erection length (P ＞ 0.05 ).ConclusionsSurgeon should pay more attention to the correction,effect evaluated,classified etiology and pathological diagnosis of hypospadias and chordee.And the targeted selection of the correct treatment of chordee can further improve the therapeutic effect.Chordee of hypospadias can exist in single or merged according to the pathological classification.Chordee correction surgery can increase length of penis,and dorsal tunica albuginea plication had no significantly different effect on the length of the penis compared to other chordee corrective surgery.

Single Stage Urethroplasty for Proximal Hypospadias with Chordee.

Proximal hypospadias with chordee usually requires two stage procedures: 1st stage is orthoplasty and ventral parking of prepucial skin and 2nd stage is urethroplasty after 6 months of 1st stage. The aim of this study is to describe and report the outcome of a single stage repair- Koyanagi Nanamura procedure for proximal hypospadias with chordee. Between January 2006 to December 2010, 44 boys with proximal hypospadias underwent repair using the Koyanagi Nanamura technique in Paediatric Surgery Department of Faridpur Medical College Hospital and Dhaka Medical College Hospital. The boys' age ranged from 1 to 7 years. The technique employs the use of lateral penile skin and extends into the inner preputial skin. This flap enjoys double blood supply from the base of the meatus as well as the preputial vessels. Follow-up period was 6 months. Satisfactory results were obtained in 39 (88.6%) patients. Three patients developed fistulae. Two patients developed meatal stenosis. Results were considered satisfactory when the boy achieves a glanular meatus, single forward stream, unimpeded voiding, good cosmesis, and no need for secondary surgery for the urethra. Koyanagi Nanamura procedure is a reliable procedure in which the lateral flaps have dual blood supply, which produces good results (88.6%) and is suitable for proximal forms of hypospadias with chordee.

Pênis curvo congênito chordee / Congenital penile curvature chordee

O chordee é a causa mais comum de curvatura ventral na hipospadia e também em muitos casos de curvatura ventral sem hipospadia esta última não é muito assinalada. A curvatura ventral sem hipospadia é um defeito congênito decorrente da ação insuficiente dos hormônios produzidos pelos testículos, os quais estimulam o desenvolvimento masculino. Clinicamente, chordee sem hipospadia é uma curvatura ventral entretanto, o meato da uretra está localizado em sua posição normal na glande e o tecido fibroso é o principal responsável pelo encurvamento. Para a correção da angulação do pênis, várias técnicas cirúrgicas têm sido descritas. Todavia, adotando um conceito diferente sobre a curvatura ventral, tenho utilizado o método progressivo para corrigir a deformidade. Acredito que, em princípio, a clássica excisão do tecido fibroso da face ventral até o meato uretral é o procedimento mais apropriado e frequentemente será suficiente para conseguir a adequada retificação do falo.

Locating the chordee in hypospadias

Ten patients with hypospadias were included in this study. The type of hypospadias and the degree of penile bowing were described. The location and the extent of the fibrotic tissue representing the chordee were defined in relation to the corpus spongiosum, the hypospadic meatus, and the urethral plate. A common finding among all ten patients was that the location of the fibrosis extended from the area proximal to the meatus to the proximal edge of the glans penis. Splaying of the fibrotic tissue resulting in its fan-shaped formation, as classically described in most textbooks, was not noted. The relationship of the fibrotic tissue to the corpus spongiosum, to the urethral meatus, and to the urethral plate was found to be inconsistent.
