Objective: To evaluate the outcomes of flouroscopy-free retrograde intrarenal surgery (ffRIRS) and to investigate the factors that may affect stone-free rate. Materials and methods: The charts of patients who underwent ffRIRS between January 2017 and August 2019 were reviewed retrospectively. Patients with missing preoperative imaging and patients with kidney anomalies were excluded from the study. Age, gender, stone size, stone localization, stone density, laterality, operation time, stone-free rate, complications and auxiliary procedures were recorded and analyzed. Results: Study group involved 44 (43.1%) female and 58 (56.8%) male patients. Stone-free rate in a single-session ffRIRS were found to be correlated with stone localization (p = 0.003), stone volume (p = 0.004), and stone density (p = 0.009) but not with age (p = 0.950). Patients with multiple calyceal stones and a stone burden over 520 mm3 were found to be less stone-free. The complication rate in female gender (n = 7) was significantly higher compared to male (n = 1) (p = 0.011). No major complications such as ureteral injury or avulsion were observed. Overall, 13 patients (12.7%) needed auxiliary procedures. The operation time seemed to be affected by stone size and gender (p = 0.005; p = 0.044, respectively). Conclusions: Stone-free rate in ffRIRS were found to be affected by stone density, size, and localization. Patients with multiple caliceal stones and high stone burden (< 520 mm3) have been found to have low stone-free rate, so one can speculate that having fluoroscopy assistance in RIRS might help us to improve surgical success.

A parameatal urethral cyst, which is a very rare congenital anomaly, was first reported in two male cases in 1956 by Thompson and Lantin. We report the case of a 20-year-old male having a spherical, cystic swelling, 7 mm in size at the external urethral meatus. The diagnosis was made by physical examination and ultrasonography. The cyst was completely excised under general anesthesia. Histologically, the cyst wall was lined by a columnar pseudo-stratified and squamous epithelium. Good cosmetic results without recurrence were achieved during the 6-month postoperative period. A parameatal cyst should be treated with complete surgical excision. Puncture of the cyst with a needle or surgical incision may result in recurrence.

Çocuklarda testis tümörünün standart tedavisi radikal orşiektomi olmasına rağmen tümör boyutları, belirteçleri ve histopatolojik bulgulara göre uygun olgularda testis koruyucu cerrahi (TKC) alternatif bir yöntemdir. Bu olgu sunumunda yaşları 11 ve 12 olan TKC uygulanan iki hastanın sunulması amaçlanmıştır. İki hastada da frozen incelemesi yapılmıştır. Bir hastada peroperatif ultrasonografi eşliğinde kitle eksizyonu yapılmıştır. Histopatolojik incelemede bir hastada epidermoid kist ve diğer hastada leydig hücre hiperplazisi olarak raporlanmıştır. Testis koruyucu cerrahi küçük testis kitlesi ve negatif tümör belirteçleri olan çocuklarda uygulanabilir.
