Aim: To compare the effectiveness of Stone Cone™, PercSys and lidocaine jelly instillation to prevent stone migration during ureterorenoscopy (URS). Materialsand Methods: One hundred patients who underwent URS for proximal ureteral stones between 2007 and 2012 were evaluated prospectively. The patients were divided into four groups consecutively. The control group (Group I) consisted of the 25 consecutive patients, in whom no device or method was used to prevent stone migration. Group II consisted of 25 patients treated with the Stone Cone, group III consisted of 25 patients treated with PercSys, and group IV consisted of 25 patients treated with lidocaine jelly instillation. Results: The migration rates were 4.5% in group II, 8.7% in group III, 21.7% in group IV, and 31.8% in group I. The migration rate was found to be statistically significantly lower in the groups treated with the Stone Cone and PercSys compared to the control group (p = 0.014, p = 0.048). However, there was no statistically significant difference between the lidocaine jelly group and the control group in terms of migration rates (p = 0.444). Conclusions: Our results suggested that the Stone Cone and PercSys were the most successful methods with significantly low migration rates (4.5 and 8.7%, respectively).

Background: We investigate the predictability of medical expulsive therapy (MET) success with alpha blockers based on Hounsfield unit (HU) values and Hounsfield density (HD) values measured by computed tomography (CT) for distal ureteral stones. Methods: Between July 2011 and May 2012, 44 patients (19 female and 25 male) with 5-to 10-mm stones in the distal ureters were included in this randomized prospective study. Non-contrast CT examinations were performed in these patients. HU and HD values of stones were calculated. Doxazosine, 4 mg/day orally, was administered as a single dose to all patients for MET. Results: Patients were divided into 2 groups. Group 1 included 18 patients (43.9%) with dropped stones with MET. Group 2 included 23 patients (56.1%) with no stone passage with MET. In Group 1, the mean stone size was 7.7 mm, the mean HU was 507, and the HD was 53.04/mm. In Group 2, the mean stone size was 8.25 mm, the mean HU was 625, and the mean HD was 61.54/mm. The HU and HD values in Group 2 were higher than in Group 1. However, there was no statistically significant difference (p = 0.85 and 0.93 for HU and HD, respectively). Interpretation: We found that HU and HD values cannot be used to predict the chances of success for MET. Although the sample size is appropriate for the study, further comparative studies involving more patients are warranted.

Purpose:To compare transobturator midurethral sling (TOS) and single-incision sling procedures in terms of their effects on urinary incontinence and the quality of life in overweight (BMI ≥25-29.9 kg/m2) female patients using the International Consultation on Incontinence Questionnaire scoring form (ICIQ-SF) and Quality of Life of Persons with Urinary Incontinence scoring form (I-QOL).Materials and Methods:In this prospective trial, the patients were divided into two groups consecutively; first 20 overweight female patients underwent the TOS (Unitape T®,Promedon, Cordoba, Argentina) procedure and the subsequent 20 consecutive overweight female patients underwent the single-incision sling [TVT-secur (Ethicon Inc., Sommerville, USA)] procedure. Age, urinary incontinence period, parity and daily pads usage were recorded. No usage of pads was defined as subjective cure rate postoperatively. Before the operation and 6. month after the surgery, the patients completed the ICIQ-SF and I-QOL.Results:There was no significant difference between the two groups in terms of mean age, duration of incontinence, parity, and BMI (p>0.05). ICIQ-SF and I-QOL revealed that the patients in the TOS group showed significantly better improvement (76.20% versus 64.10%, p=0.001, 81.31% versus 69.28%, p=0.001, respectively). In addition, subjective cure rates were found higher in TOS group (75% versus 55%, p=0.190).Conclusions:The existing data is showed that incontinence symptoms and the quality of life have higher improvement in overweight female patients who underwent the TOS procedure. It is likely that the TOS procedure may provide stronger urethral support and better contributes to continence in this group of patients.

Amyloidosis is a benign, non-neoplastic disease characterized by the deposition of extracellular fibrillar protein in tissues or organs, which may be systemic or localized. Primary amyloidosis localized in the bladder is very rare in the literature and may mimic bladder cancer at presentation. A 31-year-old female patient consulted to our clinic and was diagnosed with primary bladder amyloidosis; intravesical dimethyl sulfoxide (DMSO) therapy was started. To the best of our knowledge, this patient represents the fourth case in the Turkish medical literature.
