Effect of scrotal incision orchiopexy on serum inhibin B levels and comparison with classic inguinal orchiopexy.

OBJECTIVES: Inhibin B reveals Sertoli cell activity. After our previous findings of an increase in inhibin B succeeding classic inguinal orchiopexy, we sought to determine the changes in endocrine parameters after scrotal orchiopexy in patients with cryptorchidism and to compare these findings with the results of classic orchiopexy. METHODS: A total of 50 boys with an undescended testis, 32 unilateral and 18 bilateral, were included in the present study. Scrotal orchiopexy was performed in all of them. Before and 6 months after orchiopexy, the serum basal inhibin B and other serum hormonal levels were measured in all patients. RESULTS: The mean serum basal inhibin B levels had significantly increased and the other reproductive hormonal levels had not changed at 6 months after successful scrotal orchiopexy in our 50 patients (P = 0.016). Within the subgroups, the increase in inhibin B levels was significant in only those 2-9 years old with a unilateral undescended testis. The increase in inhibin B in those 10-12 years old with unilateral or bilateral undescended testis resulted from the start of puberty. No significant difference was found in terms of an increase in inhibin B after classic and scrotal orchiopexy. CONCLUSIONS: The measurement of inhibin B levels could be used as a follow-up parameter after orchiopexy. The serum inhibin B level increases after scrotal incision orchiopexy just as after classic inguinal orchiopexy. The increased level of inhibin B might indicate that the orchiopexy has been beneficial.

Evaluation of urinary inverted papillomas: a report of 13 cases and literature review.

Inverted papilloma (IP) of the urothelium accounts for 2.2% of urothelial neoplasms. The aim of this study was to report the results of 13 patients with urinary IP, pointing out the clinical features, presentations, treatment options and outcomes. The mean age and mean follow-up periods of the patients were 60.23 +/- 3.25 (range, 44-81) years and 30 (range, 6-42) months, respectively. There was no coexistence of urothelial carcinoma with IP at presentation. Cystoscopy showed a solitary papillary tumor in the bladders of 11 patients and solid pedunculated tumors in the remaining two patients. The site of development was the bladder in 12 cases (92%) and ureter in one (8%) case. Transurethral bladder tumor resection was performed in 12 cases. For the case with IP in the ureter, nephroureterectomy was performed. Pathologic examination demonstrated that seven of the 13 cases were of the trabecular type and six were of the glandular type. Of the 13 cases, two (7%) had recurrence, at 1 year and 1 month and 1 year and 5 months from initial resection. The male to female ratio was 5.5:1. Initial symptoms included macroscopic hematuria in five cases, microscopic hematuria in four, and dysuria and microscopic hematuria in three; one case was asymptomatic. IPs of the urinary bladder are benign tumors that can be treated successfully by transurethral resection and fulguration of the tumor bed. In addition, these lesions must be followed up closely for recurrence and malignant transformation.

Effect of biofeedback treatment on spinning top urethra in children with voiding dysfunction.

OBJECTIVES: Spinning top urethra (STU) deformity arises secondary to detrusor instability, leading to an increase in the intravesical pressure against a closed sphincter. We retrospectively analyzed the effect of biofeedback treatment on STU in children with dysfunctional voiding. METHODS: A total of 121 patients with STU and voiding dysfunction were enrolled in this study. The patients divided into two groups. Group 1 (n = 49) were treated with simple bladder retraining with timed voiding, and group 2 (n = 72) were treated with biofeedback therapy. Voiding cystourethrography was performed 6 and 12 month later to determine the status of the STU after both therapies. RESULTS: The patient age range was 5 to 13 years (mean 8.1 +/- 1.9) in group 1 and 5 to 13 years (mean 8.2 +/- 1.7) in group 2. Group 1 consisted of 41 girls and 8 boys; group 2 consisted of 63 girls and 9 boys. Voiding cystourethrography revealed vesicoureteral reflux in 39 and 59 children in groups 1 and 2, respectively. The improvement rates of the biofeedback therapy in children with STU and vesicoureteral reflux were significantly greater than the children treated with timed voiding at 6 months and 1-year of follow-up. CONCLUSIONS: For children admitted to urology clinics with urinary infection or complaints thought to be an unstable urinary bladder, proximal urethral dilation called STU is detected at a high frequency. It should be remembered that this situation can be related to vesicoureteral reflux and urinary bladder instability. Biofeedback training is a simple, effective, and well-tolerated treatment modality for these children.

Results of biofeedback treatment on reflux resolution rates in children with dysfunctional voiding and vesicoureteral reflux.

OBJECTIVES: It is well known that a relationship exists between vesicoureteral reflux (VUR) and dysfunctional voiding, and the spontaneous resolution rate in older children is lower than the rate in younger children. In this study, we analyzed our experience with biofeedback treatment in older children with confirmed voiding dysfunction and VUR and investigated the effect of this treatment on the reflux resolution rates in these children. METHODS: A total of 78 children, 5 to 14 years old (mean age 9), with voiding dysfunction and VUR detected by voiding cystourethrography were treated with biofeedback therapy. Voiding cystourethrography was performed 6 months after completion of the biofeedback program to determine the reflux status. The treatment results were also documented as subjective and objective improvements. RESULTS: The reflux in 98 units (20 bilateral) was grade 1 in 26, grade 2 in 32, grade 3 in 28, and grade 4 in 12. At 6 months of follow-up, VUR had resolved on voiding cystourethrography in 62 units (63%), the grade had improved in 28 units (29%), and the reflux had remained unchanged in 8 units (8%). Among the older children treated with biofeedback, we also observed improvements in nocturnal enuresis (82%), daytime wetting (70%), constipation (78%), frequency (76%), infrequency (64%), urgency (71%), staccato voiding (81%), flattened voiding (81%), bladder overactivity (82%), detrusor sphincter dyssynergia (77%), spinning top urethra (67%), and urinary tract infection (80%). CONCLUSIONS: Biofeedback therapy is applicable in older children with dysfunctional voiding and VUR and yields greater resolution rates than the historical resolution rates.

Condylomata acuminata of external urethral meatus causing infravesical obstruction.

Condyloma acuminata is one of the most common virally transmitted diseases. The most common sites for condyloma in males are the balanopreputial sulcus, frenulum and the glans' mucosa. Condylomata in the urethra is rarely seen occur and most often situated in the distal part of the urethra. A 24-year-male admitted to our clinic with complaint of papillary lesion at the urethral meatus and urinary retention. Physical examination revealed that multiple papillary lesions along the anterior urethra until 1 cm distance from the urethral meatus. Under the clinical diagnosis of condyloma acuminata, he was treated conservatively with radical local excision of the lesion and condyloma acuminatum was verified by histopathological examination. Four months after surgery, there has been no local or remote recurrence.

Using two ipsilateral double j ureteral stents for extrinsic ureteral obstruction due to colon carcinoma.

Although double J (DJ) ureteral stents are widely used in extrinsic ureteral obstruction, there are few studies using ipsilateral two DJ stents in the same ureter. We report using ipsilateral two ureteral DJ stents in the same ureter in a patient with extrinsic ureteral obstruction due to colon carcinoma.
