Background: Varicocele is the collection of dilated veins of pampiniform plexus which is the most common cause of infertility occurred in 35-40% of infertile men. Despite all the diagnostic tools exist for varicocele diagnosis; still, a physical examination is the first step., Objective: This study was done to determine the inter-observer agreement on varicoceles diagnosis., Materials and Methods: In this cross-sectional study, two expert examiners evaluated 93 men with infertility, scrotal pain, and enlarged scrotum for the presence of varicocele. The urologists examined patients independently in two separate rooms. The inter-observer agreement on varicocele grading analyzed by the Spearman Rho correlation coefficient., Results: The grading of varicocele were similar in 34 (36.5%) and 59 (63.4%) cases in the left and right side, respectively with correlation coefficient of 0.65 (0.51-0.75) and 0.25 (0.04-0.43), respectively. It implies that inter-observer agreement was substantial for left varicocele assessment and moderate for right varicocele assessment., Conclusion: Physical exam is the essential diagnostic tool for varicocele. As long as the observers educated with the same standard method the disagreements reduced to the negligible extent., Competing Interests: All authors declare that they have no conflict of interest.

Purpose: To compare dilutional effect of distilled water with saline solution as an irrigation fluid in percutaneous nephrolithotomy (PCNL)., Materials and Methods: Three hundred twenty eight adult patients (191 men, 137 women) who were candidates for PCNL were randomly assigned into two groups (distilled water, n = 158, group 1; saline solution, n = 162, group 2). Stone size, operation time, irrigation fluid volume, blood hemoglobin level, urea nitrogen, creatinine, sodium and potassium levels were checked before and at 6 and 12 hours after operation., Results: The mean age of the patients was 37.8 years, and the mean stone diameter was 31.5 mm. There was no clinical case of transurethral resection (TUR) syndrome. Serum sodium depletion was significantly more in group 1 than group 2 (P < .0001). Group 1 had significant decreased post-operative serum sodium levels (P < .0003). Similarly in group 2, postoperative serum sodium levels were significantly lower than the preoperative concentration (P < .01), but it was not the same 6 hours after the operation (P = .23). Serum sodium concentrations remained within normal limits in all cases, without causing clinical signs and symptoms of hyponatremia., Conclusion: We found that distilled water is safe irrigation fluid for PCNL in adults. In addition, it is more available and cost effective.
