OBJECTIVE: To evaluate the role of preoperative testicular shear wave elastography (SWE) in the prediction of improvement of semen analysis parameters after subinguinal microsurgical varicocele ligation in patients with primary infertility and clinically detectable varicocele. PATIENTS AND METHODS: Testicular SWE before the surgical intervention was done. Forty-eight patients were scheduled for subinguinal microsurgical varicocele ligation as a treatment option. Computer-assisted semen analysis was repeated 6 months after the intervention. RESULTS: At a cutoff value of 4.5 kPa, the stiffness index had a sensitivity of 86.4% and a specificity of 84.2% for semen parameter improvement after varicocelectomy. Correlation between different parameters of semen analysis and SWE showed a statistically significant negative correlation between SWE stiffness index and both sperm count (million/mL) and total motility. On the other hand, a nonsignificant negative correlation was found between SWE stiffness index and percentage of normal form. CONCLUSION: Testicular SWE is a good test that can be used in the assessment of male infertility with clinically detectable varicocele, and its results may predict semen parameter improvement after varicocelectomy. Further studies on a larger number of patients are needed to verify our results.

OBJECTIVE: To compare the safety, efficacy and complications of single vs multiple instillations of povidone iodine (PI) and urographin as a sclerosing agent in the treatment of chyluria. PATIENTS AND METHODS: The study included 58 patients diagnosed with chyluria between March 2006 and January 2013. The inclusion criteria were either severe attacks of chyluria or patients with mild-to-moderate chyluria who had failed conservative treatment. The patients were randomly allocated to one of two groups: those in Group A had a single instillation of a combination of PI 0.2% plus the contrast-agent urographin 76%, while those in Group B had multiple instillations of the same combination twice daily for 3 successive days. RESULTS: The mean (SD) age of the patients in Groups A and B was 38.22 (10.67) and 37.9 (10.86) years, respectively. Chyluria was severe in eight patients (14.8%), moderate in 25 (46.3%) and mild in 21 (38.9%). The success rate in Group A (single instillation) was 85.2% and in Group B (multiple instillation) was 88.9%. The recurrence rate in Group A was 14.8% with a disease-free duration (DFD) of 4-15 weeks, while in group B it was 11.1% with a DFD of 6-18 weeks. CONCLUSION: There was no significant difference between a single instillation of a combination of PI 0.2% and urographin 76% as a sclerosing agent in the treatment of chyluria and multiple instillations. However, the single instillation protocol is more cost effective with a shorter hospital stay.
