Which procedure should be chosen as a salvage operation in anterior hypospadias cases, meatal-based or onlay island flap? A comparative analysis.

We compared the outcome of flip-flap procedure (Mathieu procedure) with onlay island urethroplasty after previously failed repairs in anterior hypospadias cases. Charts of patients who underwent salvage flip-flap ( n=58) and onlay procedure ( n=24) were reviewed. Age range was 3-19 years (mean: 9+/-4.1) and 2-30 years (10.3+/-5.2) in the onlay and Mathieu groups, respectively ( p>0.05). In the onlay group, the flap was prepared from penile skin and preputial tissue in 5 and 19 cases, respectively. The meatal-based flap was laterally directed in 7 cases in the Mathieu group. The mean number of prior operations was greater in the onlay group when compared with the Mathieu group (1.85+/-1.53 vs. 1.41+/-0.65, respectively) although the difference was not statistically significant (Student's- t test, p>0.05). A total of 14 out of 58 (24.1%) and 6 out of 24 (25%) cases resulted in fistula formation in the Mathieu and island flap groups, respectively. Comparison of the rates of fistula formation did not reach statistical significance (Pearson chi(2), p=0.934). Skin dehiscence in one case and burying of the penis in another patient due to inadequacy of skin for coverage, occurred as complications in the onlay group. Splitting of the glans in 1, dehiscence of skin in 1 patient and complete breakdown of the neourethra in 1 case were the complications encountered in the Mathieu group. Both Mathieu and onlay island procedures have similar success rates as a salvage operation in anterior hypospadias cases if proper patient selection is done. The onlay procedure has been more commonly performed after a failed Mathieu procedure and the reverse rarely occurs.

Effects of unilateral testicular torsion on the blood flow of contralateral testis--an experimental study on dogs.

The effects of unilateral testicular torsion on the blood flow of the contralateral testis were investigated. Fourteen adult male dogs were recruited. Seven dogs underwent unilateral testicular torsion of 4 h duration, and the other seven dogs had a control operation. Testicular blood flow was determined by colour Doppler ultrasonography before and after the testicular torsion. Bilateral orchidectomy was performed at the end of the study and histopathological changes were evaluated. Values of peak systolic velocity, end diastolic velocity, and resistive index were not statistically significant between ipsilateral and contralateral testes in the study group (p > 0.05). On comparison with the control group, blood flow in the contralateral testes showed no statistically significant difference (p > 0.05). Oedema and congestion were seen on ipsilateral testes in the study group. No histopathological changes were noted on the contralateral testes. Minimal oedema and congestion secondary to manipulation were found in the control operation testes. We conclude that unilateral testicular torsion does not decrease contralateral testicular blood flow as shown by colour Doppler ultrasonography.

Evaluation of urethrovesical junction mobility by perineal ultrasonography in stress urinary incontinence.

Perineal ultrasonographic measurements of the cephalocaudal and the ventrodorsal components of urethro-vesical junction (UVJ) movement at rest and stress was performed in 35 patients of stress urinary incontinence (SUI) and 20 continent controls. The cephalocaudal distance of UVJ from the pubis at rest position was almost similar in both continent and incontinent groups, but there was significant difference during stress. The cephalocaudal mobility and the ventrodorsal distance from the pubis was markedly different between the two groups, both at rest and during stress. However, the ventrodorsal mobility was similar in both groups. It is concluded that the UVJ mobility of SUI cases was higher on the cephalocaudal axis than the vetrodorsal axis. The distance between UVJ and the pubis was more on the ventrodorsal axis as compared to the control group and UVJ passed down the pubic symphysis in 63% of SUI cases during stress.

Preliminary results of transurethral microwave thermotherapy in the treatment of benign prostatic hyperplasia in Turkey.

This prospective study was conducted in order to evaluate the efficacy of transurethral microwave thermotherapy (TUMT) in the treatment of benign prostatic hyperplasia (BPH). A single TUMT session of 55 min was delivered as an ambulatory procedure without anesthesia to 180 patients. 20 (69%) of the 29 patients who were catheterized due to urinary retention prior to the treatment were able to urinate freely after the treatment. In 91 patients with a follow-up of 3 months, the mean maximum flow rate (MFR) was 7.9 ml/s prior to the treatment and 12.1 ml/s after the treatment (p less than 0.02). The mean residual urine after voiding (PVR) of these patients was 104 and 54 ml before and after TUMT, respectively (p = 0.0001). The mean Madsen symptom score (SS) was 14 before and 7.5 after the treatment (p = 0.0001). The patients with pretreatment MFR higher than 7.0 ml/s, PVR less than 150 ml and SS lower than 15 benefited better from TUMT. As the findings indicated, TUMT is an alternative treatment modality in BPH in selected cases, although the number and the follow-up of our series are insufficient to draw a precise conclusion yet.

Solitary benign schwannoma in the psoas muscle.

Solitary benign schwannoma in the psoas muscle is extremely rare. Here we present a case report of a woman who had solitary benign schwannoma in the psoas muscle not associated with von Recklinghausen's disease. This is the fifth case reported in the literature.

Bilateral perineal ectopic testes.

Perineal testicular ectopia is seen very rarely, bilaterality is even more scarce and three cases have been reported in the literature. Here we present the fourth case with bilateral perineal ectopic testes.
