Introduction: Leydig cells tumors of the testis are uncommon, representing between 1 and 3% of the testicular tumors and for which the natural history and therapy are debated between radical orchitectomy and organ-sparing surgery.Subjects and methods: We report three new cases of Leydig cells tumors, treated in our department and we discuss the clinical, diagnostic and therapeutic aspects of this uncommon tumor.Results: The mean patient age was 29 years (23-37 years). Medical referral was for a testicular pain in two and gynecomastia in one case. All patients were treated surgically, through an inguinal incision and the procedure included clamping of the spermatic cord. During surgery, frozen section were analyzed in two cases and the tumor enucleation with organ-sparing surgery was performed. The other patient had an unilateral orchidectomy and controlateral tumorectomy. The mean follow-up was 40 months with no local recurrence.Conclusion: Patients diagnosed with Leydig cells tumors have a good prognosis; this study shows the safety of conservative surgery treatment, provided it is subsequently followed by close surveillance, as it preserves maximum fertility, and these tumors usually have a favorable prognosis.

Squamous cell carcinoma (SCC) in the non-bilharzial bladder is uncommon. We reviewed the peculiarity in our region of this tumor in terms of epidemiological, diagnosis, surgical treatment and outcome.

To evaluate the short and long terms results after the Mitrofanoff continent external urinary derivation in children.

The debate regarding the efficacy of varicocele repair to improve semen parameters and pregnancy rates is ongoing. Many authors suggest assisted reproductive technologies (ART) as an alternative for the management of male infertility. We intend to assess how varicocelectomy can improve pregnancy rate and semen quality and determine whether it can change patient candidacy for ART's procedures.

To describe the different features of germ cell tumors (GCT) of the testis and to assess the prognosis of these tumors based on a series of 35 patients.

Hydatid disease is still endemic in our country. The kidney is a relatively rare site, representing 2 to 4%. Laboratory tests may suggest the diagnosis, which is confirmed by radiology. Renal hydatid cyst raises therapeutic problems making sometimes conservative surgery difficult. Our objective is to find the best treatment adapted of this pathology.

Pure neuroendocrine tumors of the prostate (NETP) are rarely encountered. Their prognosis is pejorative because of their aggressiveness and their hormono-resistance.

To evaluate the efficiency of surgical inguinal varicocele repair in nonobstructive azoospermic men with varicocele and to determine predictive parameters of evolution.
