ABSTRACT Introduction: To evaluate possible factors that can guide the clinician to predict potential cases refractoriness to medical treatment for giggle incontinence (GI) and to examine the effectiveness of different treatment modalities. Material and methods: The data of 48 children referred to pediatric urology outpatient clinic between 2000 and 2013 diagnosed as GI were reviewed. Mean age, follow-up, GI frequency, associated symptoms, medical and family history were noted. Incontinence frequency differed between several per day to less than once weekly. Children were evaluated with uroflowmetry-electromyography and post-void residual urine. Clinical success was characterized as a full or partial response, or nonresponse as defined by the International Children's Continence Society. Univariate analysis was used to find potential factors including age, sex, familial history, GI frequency, treatment modality and dysfunctional voiding to predict children who would possibly not respond to treatment. Results: Mean age of the patients was 8.4 years (range 5 to 16). Mean follow-up time and mean duration of asymptomatic period were noted as 6.7±1.4 years and 14.2±2.3 months respectively. While 12 patients were treated with only behavioral urotherapy (Group-1), 11 patients were treated with alpha-adrenergic blockers and behavioral urotherapy (Group-2) and 18 patients with methylphenidate and behavioral urotherapy (Group-3). Giggle incontinence was refractory to eight children in-group 1; six children in-group 2 and eight children in-group 3. Daily GI frequency and dysfunctional voiding diagnosed on uroflowmetry-EMG were found as outstanding predictive factors for resistance to treatment modalities. Conclusions: A variety of therapies for GI have more than 50% failure rate and a standard treatment for GI has not been established. The use of medications to treat these patients would not be recommended, as they appear to add no benefit to symptoms and may introduce severe adverse effects.

ABSTRACT Objectives In this study it is aimed to compare the success and complication rates of SWL and RIRS in treatment of HSK stone disease. Materials and methods In this retrospective study data of 67 patients treated with either SWL (n=44) or RIRS (n=23) for stone disease in HSK between May 2003 to August 2014 was investigated. age, gender, stone size and multiplicity, stone free status, renal colic episodes and complication rates of the SWL and RIRS groups were compared. Results Mean age of the population was 42.5±8.2 (range: 16-78) years and mean stone size was 16.9±4.1 mm. SWL and RIRS groups were similar with regard to demographic characteristics and stone related characteristics. SFR of the SWL and RIRS groups were 47.7%(21/44 patients) and 73.9% (17/23 patients) respectively (p=0.039).Renal colic episodes were observed in 3 and 16 patients in the RIRS and SWL groups respectively (p=0.024). No statistically significant complications were observed between the SWL (8/44 patients) and RIRS (4/23) groups (p=0.936). Conclusions In HSK patients with stone disease, both SWL and RIRS are effective and safe treatment modalities. However RIRS seems to maintain higher SFRs with comparable complication rates.

Introduction Achieving stone free status (SFS) is the goal of stone surgery. In this study it is aimed to compare effectiveness of unenhanced helical computerized tomography (UHCT), KUB and ultrasonography (US) for detection of residual RFs and predicition of stone releated events following percutaneous nephrolitotomy (PNL). Materials and Methods Patients underwent PNL for radiopaque stones between November 2007 and February 2010 were followed. Patients were examined within 24-48 hours after the procedure by KUB, US and UHCT. For stone size 4 mm was accepted as cut off level of significance.Sensitivity and specificity of KUB and US for detection of RFs and value of them for prediction of stone related events were calculated. Results SFS was achieved in 95 patients (54.9%) and when cut off value of 4 mm for RFs was employed, SFS was achieved in 131 patients (75.7%). Sensitivity was 70.5% for KUB, and 52.5% for US. UHCT was shown to be significantly more efficient for detection of RFs compared to both KUB (p=0.01) and US (p=0.001). When cut off level of 4 mm employed, sensitivity of KUB and US increased to 85.7% and 57.1%. Statistical significant superiority of UHCT still remained (p value vs. KUB: 0.03 and p value vs. US: 0.008). Conclusion UHCT is the most sensitive diagnostic tool for detecting RFs after PNL. It has higher sensitivity regardless of stone size compared to KUB and US. Additionally UHCT has higher capability of predicting occurrence of stone related events.
