    Bilateral renal leiomyoma with 5 year follow-up: Case report
    (2015) Goren, Mehmet Resit; Erbay, Gurcan; Ozer, Cevahir; Goren, Vinil; Bal, Nebil; 26664510
    Renal leiomyomas are exceptionally rare benign tumours of the kidney. Although the renal leiomyomas usually do not metastasize, the differential diagnosis between renal leiomyomas and malign lesions (leiomyosarcoma or renal cell carcinoma) cannot be done by radiological examinations, but is possible by histological examination. Surgery is the preferred treatment. After surgery, the prognosis is excellent without recurrence. Although uterine leiomyomas can be multicentric, renal leiomyomas have been single lesions. We report an incidentally detected case of bilateral renal leiomyoma in a 50-year-old woman with a 5-year follow-up. We also review the literature and discuss clinical, radiological and histological features of renal leiomyomas.

    Ultrasound-Guided Shockwave Lithotripsy Reduces Radiation Exposure and Has Better Outcomes for Pediatric Cystine Stones
    (2017) Goren, Mehmet Resit; Goren, Vinil; Ozer, Cevahir; https://orcid.org/0000-0002-2001-1386; https://orcid.org/0000-0001-6037-7991; 27160372; Y-6143-2019
    Background/Aims/Objectives: To evaluate the outcomes and ionizing radiation (IR) exposure of children with cystine stones (CS) using different shockwave lithotripsy (SWL) guidance modalities. Methods: Data from pediatric patients with renal stones treated between January 2009 and August 2015 were retrospectively reviewed. Outcome results and IR exposure in patients undergoing fluoroscopy (FL)-guided SWL and ultrasonography (US)-guided SWL were compared. First-time stone formers and those treated with SWL and with complete follow-up data, including post-treatment stone analysis confirming CS were included. Results: Forty-four patients (16 girls and 28 boys) met the inclusion criteria. Results of SWL performed in 51 kidneys were analyzed. After the SWL, 41 (80.4%) of 51 kidneys were stone free, and 10 (19.6%) had clinically insignificant residual fragments (<= 3 mm) or unfragmented stones. The success rates differed between patients in Group-FL (60%) and Group- US (93.5%) (p = 0.008). Single-session success rates were higher, and prospects of retreatment were lower in Group-US ( p = 0.000 and p = 0.002, respectively). In addition, overall complications were significantly lower in Group-US ( p = 0.042). Overall IR exposure was higher in Group-FL ( p = 0.013). Conclusions: US-guided SWL is more effective for pediatric CS and should be considered a preferred treatment to reduce IR doses in children. (C) 2016 S. Karger AG, Basel
