A rare case of ureteral tuberculosis mimicking a tumor.

Isolated ureteral involvement in urogenital tuberculosis is rare. The diagnosis can be difficult to evoke. The radiological aspect often evokes tumor involvement, hence the importance of mentioning this pathology in endemic countries. The purpose of this study is to show that it will be necessary to think of ureteral tuberculosis in the presence of ureteral thickening living in an endemic country. We reported a case of ureteric tuberculosis in a 46-years old man mimicking a tumor.

Sperm DNA status in infertile patients with clinical varicocele.

OBJECTIVE: To evaluate if a potential relationship exists between sperm nuclear DNA damage and clinical varicocele and to determine the impact of clinical varicocele on standard semen parameters. MATERIALS AND METHODS: A prospective study involving 30 infertile patients with clinical varicocele and 15 controls patients referred to our laboratory for routine spermiological exploration. Spermograms were performed and analyzed according to World Health Organisation (WHO) guidelines 2010. The DNA fragmentation was detected by the terminal desoxynucleotidyl transferase-mediated deoxyuridine triphosphate biotin nick-end labeling (TUNEL) assay. RESULTS: The DNA fragmentation index (DFI) was significantly higher in patients with clinical varicocele compared to controls (13.3±3.4% versus 6.1±2.5%, P=0.0001). In addition, the DFI was positively and significantly correlated with the degree of severity of varicocele thus the DFI was 15.24±1.9% in patients with grade 3 versus 12.92±3.5% in those with grade 2(P<0.0001). However, an abnormality of at least one of the spermatic parameters was found in 90% of varicocele patients, and all semen characteristics such as sperm count, vitality, mobility and typical forms were decreased compared to the controls. Furthermore, statistically significant negative correlations were noted between sperm DNA fragmentation index and sperm concentration (P=0.0001), motility (P=0.03), and normal sperm morphology (P=0.03). CONCLUSION: Clinical varicocele generates a significant increase of sperm abnormalities and DNA damage, and these changes are positively correlated with varicocele grade. Sperm DNA damage independent of its cause, may affect the quality of the ejaculated sperm and may have implications on patient's fertility potential. LEVEL OF EVIDENCE: 3.

Multiple unusual urological locations of hydatic cysts including kidney, retrovesical and spermatic cord. A new case report.

Human hydatidosis is endemic in regions with temperate climate where pastoral farming is common. It is frequent in the southern shore of the Mediterranean, particularly in the Maghreb countries. It remains asymptomatic for long period, and the diagnosis is often delayed. The most affected organs are the liver and lungs. Hydatic disease of the urinary tract is an unusual entity. Our case concerns multiple unusual locations of hydatic disease in the urinary tract, including renal, retrovesical and spermatic cord, associated with splenic and intraperitoneal locations. Coexistence of hydatic cysts in such locations of urinary tract has not been previously reported.

[Bipolar versus monopolar transurethral resection of the prostate: a prospective randomized study]. / Résection transuréthrale de la prostate bipolaire versus monopolaire: étude prospective randomisée.

PURPOSE: To compare bipolar with standard monopolar transurethral resection of the prostate (TURP). MATERIAL AND METHODS: A prospectively randomized study was conducted between January 2010 and September 2011. Primary end points studied were efficacy (maximum flow rate [Qmax], International Prostate Symptom Score) and safety (adverse events, decline in postoperative serum sodium [Na+] and haemoglobin [Hb] levels). Secondary end points were operation time and duration of irrigation, catheterization, and hospitalization. RESULTS: Sixty consecutive patients were randomized and completed the study, with 29 patients in the monopolar TURP group and 31 in the TURIS group. At baseline, the two groups were comparable in age, prostate volume, mean prostate-specific antigen value, International Prostate Symptom Score, and they had at least 12 months of follow-up. Declines in the mean postoperative serum Na+ for bipolar and monopolar TURP groups were 1.2 and 8.7 mmol/L, respectively. However, there was no statistical difference in the decline in postoperative Hb between the two groups. The mean catheterization time was 26.6 and 52 hours in the bipolar and standard groups, respectively. This difference was statistically significant as was the difference in the time to hospital discharge. The IPSS and Qmax improvements were comparable between the two groups at 12 months of follow-up. CONCLUSION: No clinically relevant differences in short-term efficacy are existed between the two techniques, but bipolar TURP is preferable due to a more favorable safety profile and shorter catheterization duration.

Surgery for testicular cancer: indication, results and technical aspects.

The standard therapeutique approach to patients with advanced germ cell tumors of the testis is a combination of systemic chemotherapy with surgical removal of the residual disease. The indication of surgery, residual tumor resection (RTR) or retroperitoneal lymph node dissection (RPLND), has changed during the last 10 years. Sugery is not longer recommended after chemotherapy of pure seminoma and surveillance of the residual tumor is the favored option. RPLND is a critical component of the treatment armentarium in low-stage nonseminomatous germ cell. RPLND is an accurate staging tool prviding important information to dtermine the need for chemotherapy. When performed properly, RPLND eliminates the retroperitoneum as a site for relapse, wich in turn provides emotional and psychological relief to the patient, and simplifies the follow-up protocol. In advanced nonseminomatous tumours, surgery after chemotherapy is recommended in most of the cases since large studies have shown that a considerable proportion of patients with complete radiological remission after chemotherapy harbor vital carcinoma or teratoma. Prediction models of necrosis after chemotherapy in order to avoid RTR are generally accepted since the accuracy of most models is too low. RTR is indicated in patients with elevated markers after two different chemotherapy regimens (including salvage chemotherapy) either to resect teratoma or cystic residual disease or to remove chemorefractory disease. Laparoscopic approache is a viable staging tool; however, oncologic control of the retroperitoneum has not been reliably determined.

[Results of BCG in the treatment of pTa and pT1 bladder tumors. Evaluation of a long protocol using 75 mg of Pasteur strain BCG]. / Résultats du BCG dans le traitement des tumeurs de vessie pTa et pT1. Evaluation d'un protocole long utilisant 75 mg de BCG de souche Pasteur.

OBJECTIVES: Evaluation of a protocol of intravesical BCG therapy using 75 mg of Pasteur strain BCG with 2 years of maintenance treatment, and a follow-up of up to 60 months. MATERIAL AND METHODS: 189 patients treated by transurethral resection (TUR) for a pTa (N = 80) or pT1 (N = 109) bladder tumour were included in the study. The local and general safety was excellent. We retrospectively compared this series to a group of patients treated by TUR alone (N = 42) another group treated with TUR and Mitomycin C (MMC) (N = 81). The 3 groups were statistically comparable. RESULTS: At 48 months, 62% of patients treated with BCG were recurrence-free, versus only 18% for patients treated with TUR alone and 38% for patients treated with TUR and MMC (p = 0.001). At 42 months, 11% of pT1 tumours treated with BCG had progressed to invasive carcinoma, and this progression occurred during the first 18 months in every case. In comparison, this progression was observed in 25% of pT1 tumours treated by TUR alone and 21% of tumours treated with TUR and MMC. CONCLUSIONS: Our study confirms the efficacy of our BCG protocol ro reduce the potential for recurrence and progression of superficial bladder tumours, despite reduction of the dose to 75 mg. It also suggests the superiority of BCG compared to MMC in terms of recurrence and progression.
