    Purpose: Hemorrhagic cystitis (HC) is the most common urotoxic side effect of cyclophosphamide (CYP). Platelet rich plasma (PRP) plays an important role in wound healing and inflammatory responses. The aim of this study was to investigate the efficacy of intravesical PRP at treatment of interstitial cystitis (IC). Material-Methods: Female rats (n=24) were used. IC was induced by intraperitoneal injection of cyclophosphamide (CYP). Rats were randomly allocated to one of four groups (n = 6 per group): a control group; a sham group with saline (75 mg/kg; i.p.) instead of CYP on day 1; a IC group, which was injected with CYP (150 mg/kg; i.p.) on day 1; and, a intravesical PRP-treated group which was injected with CYP (150 mg/kg; i.p.) on day 1. On day 2, the rats in each group were sacrificed under anesthesia. Results: Histological evaluation showed that bladder inflammation in CYP-treated rats was not suppressed by PRP. CYP administration induced severe IC with marked edema, hemorrhage and inflammation in CYP and CYP+PRP groups, but PRP was not found to be effective to decrease these effects. Conclusion: The application of PRP could not reverse the histopathological changes in rats that had interstitial cystitis due to the cyclophosphamide injection. © 2017 Elsevier B.V., All rights reserved.

    The association between serum follicle-stimulating hormone levels and the success of microdissection testicular sperm extraction in patients with azoospermia
    (Urology and Nephrology Research Centre info@unrc.ir, 2014) Yıldırım, Mehmet Erol; Koç, Akif; Kaygusuz, İkbal Cekmen; Badem, Hüseyin; Karataş, Ömer Faruk; Çimentepe, Ersin In; Ünal, Doğan
    Purpose: To evaluate the predictive power of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, testicular biopsy histology and male age were evaluated with respect to the success of sperm retrieval in a microdissection testicular sperm extraction (microTESE) procedure, pregnancy and live birth rates. Materials and Methods: We examined the data of 131 infertile men with non-obstructive azoospermia, who have undergone microTESE operation. The men were classified into two groups based on serum follicle-stimulating hormone (FSH) levels ? 15 mIU/mL (group 1) and > 15 mIU/mL (group 2). Results: Group 1 consisted of 59 patients (mean age 36.2 ± 6.2 years) and group 2 consisted of 72 (mean age 38.8 ± 7.4 years) patients. Sperm retrieval and pregnancy rates were 66.1% and 16.9% in normal FSH group, respectively. These parameters were higher than those of men with FSH > 15 (43% and 8.3%, respectively). Only 128 patients had histopathological diagnosis. Sperm was retrieved from 12/30 (40%) patients with maturation arrest, 9/29 (31.03%) patients with seminiferous tubules atrophy, 14/40 (35%) patients with sertoli cell only syndrome and 13/13 (100%) of patients with hypospermatogenesis. There was no statistically significant difference in pathological diagnosis between pregnancy and live birth rates. Conclusion: These results demonstrate that there is a significant difference with sperm retrieval, pregnancy rates and live birth rates comparing the FSH levels. Histopathological findings did not associate with successful microTESE, pregnancy rates and live birth rates. © 2015 Elsevier B.V., All rights reserved.
