Giant prostatic urethral calculus associated with urethrocutaneous fistula

Abstract  Urethral stones in men are rare clinical entity and most of them migrate from the urinary bladder. Urethral stones are rarely formed primarily in the urethra and are usually associated with urethral strictures or diverticula. We report a 41‐year‐old man with giant prostatic urethral stone (5.9 × 3.2 × 2.8 cm) associated with a urethrocutaneous fistula. The etiological factors, pathogenesis, clinical presentation, complications and management of giant urethral calculi are reviewed.

Bilateral synchronous granulomatous orchitis: gray-scale and colour Doppler sonographic findings.

A 60-year-old man presented with impotence ultrasonography demonstrated bilateral irregular hypoechoic infiltration of testes and normal epididymis. Colour Doppler sonography showed only peripheral but no intralesional flow. Since the lesion was presumed as malignancy bilateral high inguinal orchiectomy was performed and bilateral idiopathic granulomatous orchitis was diagnosed. It was concluded that granulomatous orchitis should be considered in the differential diagnosis of diffuse testicular hypoechoic involvement which showed only peripheral low-resistance flow on colour Doppler sonography, in the proper clinical setting. Although this may be a helpful sign in the differential diagnosis of diffuse testicular infiltrations, high inguinal exploration remains mandatory.

The use of human dura mater as an interposition graft in the treatment of vesicovaginal fistula

Purpose: In this prospective study we aimed to describe our new technique; dehydrated human dura mater as an interposition graft in patients undergoing benign vesicovaginal fistula repair (VVF). Patients and methods: Eleven patients with benign VVFs aged 38–73 years were operated with dura mater interposition technique at our institution between July 1996 and February 2002. In all patients fistula were secondary to abdominal hysterectomies with benign diseases and two had undergone previous transvaginal surgery. Patients were operated 8–15 (mean 12) weeks after previous surgery. A suprapubic cystotomy was performed and the fistula was not excised. The bladder wall is widely dissected from underlying vagina. Dura-mater was placed over the vaginal suture line to close the fistulous tract, cytostomy was inserted and the bladder was closed. An 18 F Foley catheter was left in the bladder for 5 days. A successful repair is defined as no leakage by cystogram at 14 days postoperatively and completely dry by patient report. Results: An overall success rate of 100% was achieved in all patients. All patients remain dry at the follow – up which ranges from 7 to 60 (mean 26) mounts. Patients were discharged at 14 to 26 (mean 16) days postoperatively. No major complications or side effects were observed during the follow-up period. Conclusions: The use of human dura mater as an interposition graft in the treatment of vesicovaginal fistula is an alternative for VVF repairs because of its excellent tissue compability, stability, good elasticity and absorbability.

Expression of the cyclin-dependent kinase inhibitor p27 in transitional cell bladder cancers: is it a good predictor for tumor behavior?

Objectives: Progression of the cell cycleis regulated by the interactions of cyclins,cyclin dependent kinases (CDKs) and CDKinhibitors (CDKIs). p27 is a member of theuniversal cyclin-dependent kinase inhibitorfamily. The level of p27 protein expressiondecreases during tumor development andprogression in some epithelial, lymphoid andendocrine tissues. It has been suggested thatp27 is an independent prognostic factor invarious human cancers. The prognostic value ofp27 protein expression is not completelyunderstood in bladder cancer yet.Aims: To investigate theimmunohistochemical expression of p27 intransitional cell bladder cancers and itsrelationship with clinicopathological data,proliferating cell nuclear antigen (PCNA) andp53 oncoprotein immunoreactivity.Methods: The expression of p27 proteinwas immunohistochemically analyzed inparaffin-embedded specimens of 75 patients withtransitional cell carcinoma of the bladder. p27expression was compared with tumor grade,stage, growth pattern, disease-free survival,progression, PCNA and p53 immunoreactivity.Results: Expression of p27 was notsignificantly related to clinicopathologicparameters, disease-free survival, progression,PCNA and p53 immunoreactivity.Conclusion: The results indicate that p27is not a good predictor for outcome oftransitional cell carcinoma of the bladder.

Failure of artificial insemination of husband's semen in the treatment of male infertility

In the management of infertility, in case semen quality is found insufficient and could not be improved by medical means, handling the available spermatozoa in the most beneficial way has been aimed. Thus, artificial insemination with low quality semen has become a therapeutic alternative. In this study homologous artificial insemination has been used to treat infertility caused by oligoasthenospermia. Eighteen couples have been treated for 58 cycles by intrauterine or paracervical insemination using cervical cups. During the same period 42 cycles with timed vaginal intercourse have been assessed. Though no pregnancies could be obtained following artificial insemination, one pregnancy occurred during no-treatment cycles.

Chondrosarcoma of the pubis imitating bladder tumor radiologically: a case report.

Chondrosarcoma is a rare tumor that more frequently involves the pelvic bones, the femur, and the humerus [1, 2]. The rareness of the tumor makes the diagnosis difficult. Malignant cartilage tumors typically have an unstable radiographic appearance [3]. In this report we aimed to point out the difficulties of the radiological differentiation of the pelvic chondrosarcoma and bladder tumor.

Paratesticular rhabdomyosarcoma in a 2-year-old boy.

Paratesticular rhabdomyosarcoma is a rare but highly malign tumor. We report a case of paratesticular rhabdomyosarcoma and discuss the management of this neoplasm in the light of the literature.
