RESUMO

Spermatozoa can be retrieved in non-obstructive azoospermia (NOA) patients despite the absence of ejaculated spermatozoa in their semen because of the presence of isolated foci with active spermatogenesis. Conventional testicular sperm extraction (c-TESE) in patients with NOA has been partially replaced by micro-TESE. It is still under debate the problem regarding the higher costs related to micro-TESE when compared with c-TESE. In this study, we evaluated sperm retrieval rate (SRR) of c-TESE in naive NOA patients. Sixty-three NOA patients were referred to our centre for a c-TESE. For every subject, we collected demographic data, cause of infertility, time to first infertility diagnosis, serum levels of LH, FSH, total testosterone and prolactin. A statistical analysis was conducted to correlate all the clinical variables, the histology and the Johnsen score with the SRR. Sixty-three consecutive NOA patients with a mean age of 37.3 years were included. The positive SRR was 47.6%. No statistical differences were observed between positive vs. negative SRR regarding mean FSH (17.12 vs. 19.03 mUI/mL; p = 0.72), and LH (9.72 vs. 6.92 mUI/mL; p = 0.39) values. Interestingly, we found a statistically significant difference in terms of time to first infertility diagnosis (+SRR vs. -SRR; 44.5 vs. 57 months; p = 0.02) and regarding to age (+SSR vs. -SRR; 40.1 vs. 35.3; p = 0.04). There was a statistically significant decrease in SRRs with the decline in testicular histopathology from hypospermatogenesis to maturation arrest, and SCO. The mean Johnsen score was 5.9 with a mean percentage of Johnsen score ≥8 tubules equal to 19%. The overall pregnancy rate was 26.6%. In our prospective cohort of patients successful SRR with c-TESE was 47.6%. Lower costs and high reproducibility of this technique still support this procedure as an actual reliable option in NOA patients for sperm retrieval.

RESUMO

INTRODUCTION: Superficial bladder cancer can be treated by transurethral resection (TUR) and adjuvant intravesical therapy. Intravesical bacillus Calmette-Guérin (BCG) has been proven to be more efficacious with respect to recurrence prevention than intravesical chemotherapy, although at the cost of more severe side effects. There is a need for a new treatment modality with higher efficacy and less toxicity. The subject of this study is the efficacy of local microwave hyperthermia and chemotherapy treatment in intermediate or high risk superficial transitional cell carcinoma (TCC) of the bladder. PATIENTS AND METHODS: Ninety eligible patients received adjuvant treatment with a combination of mitomycin-C (MMC) and local microwave hyperthermia. All patients had multiple or recurrent Ta or T1 TCC of the bladder and were classified as intermediate or high risk according to EAU criteria. In total, 41 patients were BCG failures. The treatment regimen included 6 to 8 weekly sessions followed by 4 to 6 monthly sessions. Follow-up consisted of video-cystoscopy and urine cytology every 3 months. All patients were observed for 2 years. RESULTS: Kaplan-Meier analyses of the total group (N = 90) indicated that 1 year after treatment only 14.3% (SE 4.5%) of all patients experienced a recurrence. After 2 years of follow-up the risk of recurrence was 24.6% (SE 5.9%). No progression in stage and grade was observed. CONCLUSION: Microwave induced hyperthermia combined with MMC has promising value in intermediate or high risk superficial bladder cancer patients compared to literature data of BCG and/or intravesical chemotherapy, particularly where other treatments, i.e. BCG, have failed.

RESUMO

OBJECTIVES: To evaluate the effectiveness of combined local bladder hyperthermia and intravesical chemotherapy for the treatment of patients with high-grade (G3) superficial bladder cancer. METHODS: Patients with G3 bladder tumors (Stage Ta or T1) were treated with combined intravesical chemotherapy with mitomycin-C and local radiofrequency hyperthermia of the bladder wall. The patients were treated with either a prophylactic protocol (40 mg mitomycin-C) after complete transurethral resection of all tumors or with an ablative protocol (80 mg mitomycin-C) when visible tumor was seen on video-cystoscopy or bladder biopsies were positive for carcinoma in situ. RESULTS: Combined chemo-thermotherapy was administered to 52 patients with high-grade superficial bladder cancer (40 patients with Stage T1 tumor, 11 with Ta, and 3 with concomitant or isolated carcinoma in situ). At a median follow-up of 15.2 months (mean 23, range 6 to 90), no stage progression to T2 or disease-related mortality had occurred. The bladder preservation rate was 86.5%. The prophylactic protocol was administered to 24 patients. After a mean follow-up of 35.3 months, 15 patients (62.5%) were recurrence free. The bladder preservation rate was 95.8%. The ablative protocol was administered to 28 patients. Complete ablation of the tumor was accomplished in 21 patients (75%). After a mean follow-up of 20 months, 80.9% of these patients were recurrence free. The bladder preservation rate for the ablative group was 78.6%. CONCLUSIONS: Combined local bladder hyperthermia and intravesical chemotherapy has a beneficial prophylactic effect in patients with G3 superficial bladder cancer. Ablation of high-grade bladder tumors is feasible, achieving a complete response in about three quarters of the patients.

RESUMO

Since it was initially described in 1992 laparoscopic adrenalectomy (LA) has been gaining popularity amongst urologists and its range of applications has progressively widened. Ten years after the first report of LA this type of operation is presently considered to be the 'standard of care' for most adrenal diseases requiring surgery. We define the current role of laparoscopy in the management of surgical adrenal diseases, using a Medline search (1997-2002) to assess reports of LA, focusing on indications, approaches (transperitoneal and retroperitoneoscopic) and comparative analyses, taking particular care to evaluate operative duration, rate of conversion and transfusion, complications and hospital stay. With both approaches LA is safe and effective and, when compared with open surgery, offers the same functional results with all the advantages of minimally invasive surgery. We conclude that LA based on either approach should be considered the treatment of choice for benign adrenal lesions. Although very promising, conservative surgery and LA should still be evaluated in cases of malignancy.

RESUMO

The prevalence of superficial transitional cell carcinoma of the bladder (STCCB) is still increasing in spite of improved adjuvant chemotherapeutic and/or immunoprophylaxis approaches. Thus, there is certainly an urgent need to improve our ability to control this disease. Local hyperthermia has a therapeutical potential for the treatment of many solid tumors, especially when used in combination with other treatments, such as radiation and chemotherapy. In particular, a synergistic or, at least, supra-additive anti-tumor cell killing effect was documented when local hyperthermia was administered in combination with selected cytostatic drugs. Recently, advances in miniaturized technology have allowed the development of a system specifically designed for delivering an endovesical thermo-chemotherapy regimen in humans. In preliminary clinical experiences, insofar mainly carried out as mono-institutional investigations, the combined treatment using this system was demonstrated to be feasible, minimally invasive and safe when performed on out-patient basis. Moreover, the anti-tumoral efficacy seemed to be significantly enhanced when compared with that obtained using intravesical chemotherapy alone for both adjuvant (prophylaxis) and neo-adjuvant (ablative) approaches to superficial bladder cancer.
