目的:探讨尿道下裂术后尿道狭窄的治疗方法,研究输尿管镜联合钬激光治疗尿道下裂术后尿道狭窄的临床疗效。方法:对10例先天性尿道下裂尿道成形术后并发尿道狭窄患者进行输尿管镜下钬激光治疗,切除尿道息肉、线结及狭窄环。结果:10例患者手术顺利完成,术后3周拔除导尿管排尿通畅。结论:尿道下裂术后尿道狭窄多发生于成形尿道与原尿道交界处。传统的尿道扩张或开放手术均存在一定弊端,而输尿管镜联合钬激光治疗尿道下裂术后尿道狭窄临床疗效满意。 相似文献

Purpose
The purpose of this study was to evaluate the effectiveness of a new approach to repair the giant prostatic utricle (pseudovagina) associated with proximal hypospadias.Methods
Three patients with giant prostatic utricle associated with proximal hypospadias sought medical advice in our department from 1998 to 2003. The giant prostatic utricles were repaired using the novel approach of divesting of utricular mucosa followed by muscular tunnel obliteration through the opening of the pseudovagina in the dorsal lithotomy position.Results
Follow-up ranges from 3 to 8 years. The divesting of the prostatic utricle mucosa was successful, and the pseudovagina muscular tunnel was closed completely in all 3 patients. One patient underwent urethroplasty and another repair of urethrocutaneous fistula at the same setting. The third patient underwent a second-stage urethroplasty separately. On follow-up, both the urethral reconstruction and the pseudovagina repair remained successful in all the patients.Conclusions
The technique of the divesting of the prostatic utricle mucosa and closure of the muscular wall is an effective alternative approach for repairing giant prostatic utricles. It is safe and simple. The surgical exposure is very good. 相似文献12.
An enlarged prostatic utricle is often associated with hypospadias. To evaluate the relationship between the incidence of prostatic utricle and the degree of hypospadias, we performed retrograde urethrography and/or micturating cystourethrography on 280 patients with hypospadias. Prostatic utricles were demonstrated in 84 patients (27.5%) and the incidence increased according to the severity of hypospadias. The prostatic utricles were classified into four types from the standpoint of size and location of the opening of the utricle, and a direct relationship was demonstrated between the severity of hypospadias and increasing size of the prostatic utricle. 相似文献

Testicular function in patients with hypospadias associated with enlarged prostatic utricle. 总被引:2,自引:0,他引:2
Of 485 patients with hypospadias who underwent urethrography, enlarged prostatic utricles were found in 173 (35.7%). Utricles with a higher grade of enlargement were seen mainly in patients with a severe degree of hypospadias. Serum testosterone levels before and after 3 days' treatment with human chorionic gonadotrophin were determined by radioimmunoassay in 97 prepubertal boys with hypospadias and enlarged prostatic utricles. Lower levels of serum testosterone were found after hormonal stimulation in 22 patients with high grade utricular enlargement when compared with 5 controls and 75 patients with low grade enlargement; the difference was statistically significant. This finding supports the hypothesis that utricular enlargement may be due to androgenic insufficiency during the critical period of organogenesis. 相似文献

Surgical treatment for enlarged prostatic utricle and vagina masculina in patients with hypospadias 总被引:1,自引:0,他引:1
Fourteen patients with hypospadias were treated surgically for either an enlarged prostatic utricle (6) or vagina masculina (8). Six vaginae masculinae were removed by an extravesical abdominal approach. One enlarged prostatic utricle was removed by the perineal approach. Three enlarged utricles were removed by an abdominoperineal approach. The transtrigonal approach was recently used for three enlarged utricles and one vagina masculina in four patients. Surgical results in these 14 patients were satisfactory. One post-operative complication of transient mild bilateral vesicoureteric reflux was seen after a transtrigonal removal of an enlarged utricle. Potency was not affected in any approaches in four patients who were older than 12 years. The transtrigonal approach was found to be the best for good exposure of the lesion. 相似文献

先天性尿道下裂与SRY基因关系的探讨 总被引:6,自引:0,他引:6
目的 探讨尿道下裂与SRY基因的关系及意义。结果 采用PCR方法对42例先天性尿道下裂患者外周血白细胞进行SRY基因检测。结果 发现2例染色体核型为46,XY患者SRY基因缺失,DNA样品加入EF3、ER3引物及新Taq酶后,PCR反应结果可见332bp的Sox9基因片段,对照46,XY正常成年男性基因组DNA扩增产生436bpSRY基因片段。结论 (1)SRY基因不是性别决定的唯一基因。SRY基因缺失或突变可能导致性发育的一系列异常改变,尿道下裂的发生与SRY的缺失、变异有关。(2)先天性尿道下裂是一种性别发育异常,尿道缺失是性腺发育不全表现。(3)对尿道下裂患者进行SRY基因检测有一定的临床意义。 相似文献

The prostatic utricle, a rudimentary structure present in the male prostatic urethra, is currently thought to be of mixed origin, with its cranial portion being derived from müllerian duct and caudal segment from wolffian and müllerian ducts and the urogenital sinus. Enlargement of prostatic utricle has often been demonstrated in patients with hypospadias and its incidence increased according to the severity of hypospadias. It has been suggested that insufficient androgenic stimulation of the urogenital sinus and urethral groove during the critical period of sexual differentiation may cause this entity. Since 5 alpha-dihydrotestosterone (DHT) is a major androgen for the normal development of urogenital sinus, androgen receptor levels in the patients with hypospadias associated with enlarged prostatic utricle may concern this ontogenesis. Fibroblasts derived from penile skin in these patients were assayed for androgen receptor levels using dispersed whole cell binding assay after Eil (1970). Thermostability of androgen receptor in the same fibroblasts was also evaluated by the remaining androgen receptor activity after incubation at 42 degrees C, and expressed as a ratio (percentage) to the androgen receptor activity in the incubation at 22 degrees C. Preputial skin of endocrinologically normal boys in the same range of age (3 to 8 years) was served as controls. There was a significant difference in averages of maximum binding capacities of [3H]DHT to the androgen receptor between those of controls (n = 4) and patients with grade II utricle (n = 4) (89 +/- 5.7 (SE) x 10(2) sites/cell vs. 37 +/- 7.1 x 10(2) sites/cell).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献
