Objective: To evaluate the safety and efficacy of retrograde intrarenal surgery (RIRS) in the treatment of kidney stones greater than 2 cm and to compare its results with those of percutaneous nephrolithotomy (PCNL).
Material and methods:We retrospectively analyzed a total of 143 patients: 86 patients (53 males and 33 females) who underwent PCNL and 57 patients (37 males and 20 females) who underwent RIRS between October 2009 and October 2013.
Results:The mean duration of operation was 100.26±33.26 min in the RIRS group and 75.55±21.5 min in the PCNL group (p<0.001). The hospital stay was significantly shorter in the RIRS group (1.56±0.8 vs. 4.57±2.1 days in the RIRS and PCNL groups, respectively; p<0.001). Stone-free rates after one session were 66.6% and 91.8% of the RIRS and PCNL groups, respectively. The stone-free rate of the RIRS group improved to 87.7% after the second session. Blood transfusions were required in two patients in the PCNL group. Complication rates were higher in the PCNL group.
Conclusion:This study revealed that RIRS can be an alternative to PCNL in the treatment of kidney stones with a diameter of 2-4 cm especially in patients with comorbidities.
Objective: To evaluate the efficacy of percutaneous tibial nerve stimulation (PTNS), either alone or combined with an anticholinergic agent, in treating patients with an overactive bladder (OAB) in whom previous conservative treatment failed.
The aim in this study is to evaluate predictive factors on sperm retrieval and pregnancy rates by microdissection testicular sperm extraction in non obstructive azoospermia patients with a history of orchidopexy operation. A total of 148 patients were included, and their medical files were evaluated. Data related to possible predictive factors on sperm retrieval and pregnancy rates such as age at orchidopexy operation, unilateral or bilateral presence of undescended testis before orchidopexy, testis volumes and hormone levels were statistically analysed. It revealed that the mean ages in patients with unilateral and bilateral orchidopexy operations were 35.37 (±4.84) and 33.94 (±5.91) respectively. Mean testis volume in the unilateral orchidopexy group was 7.59 (±3.12) ml on the right testis and 7.37 (±2.86) ml on the left testis. Mean FSH levels were detected as 22.71 (±11.86) mIU/ml in the unilateral group and 28.19 (±12.40) mIU/ml in the bilateral group. In our study, we have shown that the age at which patients undergo orchidopexy and the unilateral or bilateral presence of cryptorchidism has no correlation with sperm retrieval and pregnancy rates.
The aim of this study was to investigate the antioxidant properties of udenafil citrate (1.4 mg kg(-1) -2.8 mg kg(-1) ), dexmedetomidine 25 μg kg(-1) and piracetam 200 mg kg(-1) administered on ipsilateral/contralateral testes after ischaemia in a rat model of testicular torsion/detorsion (T/D) and define its protective effect histologically. Fifty-six Wistar albino rats were included and randomly assigned into 6 groups. No intervention was performed in control group (Group 1, n = 8) and in torsion/detorsion group, (Group 2, n = 8). Udenafil 1.4 mg kg(-1) was given to torsion/detorsion group (Group 3, n = 10), udenafil 2.8 mg kg(-1) was given to torsion/detorsion group (Group 4, n = 10), piracetam 200 mg kg(-1) was given to torsion/detorsion group (Group 5, n = 10) and dexmedetomidine 25 μg kg(-1) was given to torsion/detorsion group (Group 6, n = 10) intraperitoneally after 60 mins of testicular torsion. Biochemical and histopathological testicular injury were evaluated. When the tissue was examined by TOS values, Group 3, Group 4 and Group 5 were significantly lower than Group 2. In contrary Group 6 values were significantly higher than Group 2. The increasing doses of udenafil demonstrated antioxidant properties on the testis tissue and histopathological that protects the testicles.
In this study, we detected statistically significant decrease in FSFI scores in two groups of MS compared to healthy controls. We could not define a difference in sexual function in different stages of MS in women and a statistically significant negative correlation between EDSS and FSFI scores in the two subgroups of MS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
