We report a case of a 33-year-old male with a mixed germ-cell testicular tumor. Postoperative follow-up FDG-PET revealed concentration of FDG in the left inguinal area which is not tumor metastasis or local recurrence but suture reactivity granuloma. In this paper, we reviewed suture granulomas associated with false-positive findings on FDG-PET after surgery. If FDG-PET will be used more frequently in the future, it will be necessary to refrain from using silk thread in order to prevent any unnecessary surgery.

Introduction: In this study, we investigated the effects of treatment with a transurethral incision (TUI) for congenital urethral stenosis, which was accompanied by diurnal and nocturnal enuresis. Methods: We recruited 21 young males who presented to our department for the treatment of diurnal and nocturnal enuresis from January 2010 to March 2014. All patients underwent TUI due to urethral stricture found by a close investigation. We surveyed each case to evaluate the improvement of diurnal and/or nocturnal enuresis after TUI. Results: One and a half years after TUI, an improvement in diurnal enuresis was observed in 17 of 21 cases (80.9%), whereas that of nocturnal enuresis was observe in only 7 of 21 cases (33.3%), showing the significant contribution of TUI to the improvement of diurnal enuresis (p = 0.001). In the case of diurnal enuresis, continual improvement was observed more than a year after surgery, whereas no improvement was observed in nocturnal enuresis at more than 6 months after surgery. Conclusion: TUI is more effective for diurnal enuresis than nocturnal enuresis. At postoperative 6 months, clinicians should thus consider other etiologies for unresponsive cases and start other treatment options.
