Intrauterine device is the most widely used method of reversible contraception. It may cause various complications including perforation of uterus. In this case, 44-year-old woman was presented with lower urinary tract symptoms after six years of insertion. Patient has no remarkable physical or laboratory finding but abdominal ultrasound revealed a 27 mm hyperechogenicity, suggestive of foreign body or calculus on the posterior bladder wall which was removed endoscopically. This case highlights the need of immediate and periodic evaluation of women with intrauterine device to avoid missing serious complications.

OBJECTIVE To investigate the possible protective role of insulin‐like growth factor‐1 (IGF‐1, reported to have a protective effect in experimental models of hypoxic ischaemia), and the involvement of apoptotic cell death in a model of torsion/detorsion of the rat testis. MATERIALS AND METHODS Adult male Wistar rats were divided into five groups of five rats each. Group 1 underwent a sham operation as a control; in group 2 the testis was twisted and in group 3 then untwisted; in group 4 IGF‐1 was injected subcutaneously just before bilateral torsion, and then the right testis removed after 4 h and the left after 24 h; in group 5, IGF‐1 was injected immediately after bilateral detorsion and then the testes removed as in group 4. Both testicles were examined histologically, with apoptosis detected using the in situ DNA fragmentation (TUNEL) system, with combined enzymology and immunohistochemistry techniques. RESULTS In groups 2 (torsion) and 3 (detorsion), light microscopy of the testis showed some degenerative changes in the germ cells. Compared to group 1, apoptosis was more significant in group 3 than in the other groups. Group 4 (torsion/IGF‐1) had a similar number of apoptotic germ cells as in group 2 (torsion) after 24 h, but fewer than the same group after 4 h. In group 5 (detorsion/IGF‐1), apoptosis was reduced by IGF‐1 significantly more than in group 3 (P < 0.05). Apoptosis was significantly less in spermatids in group 5 than in group 3 (P < 0.05). CONCLUSIONS IGF‐1 seems to lower the levels of germ cell apoptosis, which may be important for protecting the testes from torsion/detorsion injury. Further clinical studies are needed to evaluate this protective effect in testicular torsion/detorsion.

The results suggest that ether and midazolam are preferable to ketamine for anesthetized cystometry studies. The results were questionable for propofol, and further studies are needed to make it clear.

Physical traumas have been implicated as intrinsic risk factors for the progression of urothelial tumours. In stone disease, histologic changes of the urothelium have a wide spectrum. We want to show the importance of biopsies for identification of these changes. In this study, we investigated the histologic changes of the urothelium in stone patients. There were 16 squamous metaplasia, 14 pyelitis follicularis, 5 pyelitis or ureteritis cystica, 4 polypoid pyelitis or ureteritis, 2 encrusted pyelitis in 43 stone patients, and 5 calcium, 2 long-standing struvite and 2 mixed calculi histories were found in 9 of 14 upper urothelial tumour patients. According to our results, it is important to identify the histologic changes of the upper urothelium during stone surgery for possible neoplastic progression in the future. If any suspicious finding is demonstrated, the patients should be enrolled in a follow-up programme or should be transferred to tumour treatment programme. Therefore, we propose to take biopsies of the urothelium in every stone surgery.

To the best of our knowledge, this is the first study ever to show that overactive detrusor is an accompanying entity in the hypospadic patients.
