PURPOSE: Ureteroureterostomy is a treatment modality for managing an ectopic ureterocele or ectopic ureter and preserving upper pole kidney function. However, the development of urinary tract infection at the residual ureteral stump is a concern. We analyzed factors affecting the development of urinary tract infection at the residual ureteral stump after proximal ureteroureterostomy. MATERIALS AND METHODS: Between January 2002 and December 2009 proximal ureteroureterostomy was performed in 80 pa

Exosomes, naturally secreted nanoparticles, have been introduced as vehicles for horizontal transfer of genetic material. We induced autologous exosomes containing a cocktail of reprogramming factors ("reprosomes") to convert fibroblasts into neural progenitor cells (NPCs). The fibroblasts were treated with ultrasound and subsequently cultured in neural stem cell medium for 1 day to induce the release of reprosomes composed of reprogramming factors associated with chromatin remodeling and neural

Quantitative measurements of renal echogenicity using a graphic program show close correlation with renal histology in adult patients, but this has neither been applied in pediatric patients nor correlated with glomerular filtration rate (GFR). To determine the direct relationship between echogenicity and GFR, we retrospectively analyzed 91 patients with a solitary functioning kidney under the age of 10, who underwent ultrasonography and serum cystatin C evaluation on a single day between Januar

본 연구에서는 최근 Sato 등이 고안한 mixing ability index(MAI)를 이용하여 측두하악장애 환자 중 통증이 있는 군과 무통성 관절잡음이 있는 군을 대상으로 객관적인 저작 효율을 정상인으로 구성된 대조군과 비교하고, 주관적인 평가 방법인 설문조사법 중에서 음식섭취가능지수(Food Intake Ability Index, FIA)와 저작 능력에 대한 주관적 인식도 평가(Visual Analogue Scale, VAS)를 이용하여 저작 효율을 평가하고, 구강건강과 관련된 삶의 질을 평가하기 위해 Oral Health Impact Profile(OHIP)-49K 설문조사를 시행하였다. 각 평가 방법 간의 상관성을 알아보고, 또한 통증군에 있어서는 치료 후 통증이 감소함에 따라 저작 효율의 변화 양상을 조사하여 다음과 같은 결과를 얻었다. 1. MAI, FIA, VAS는 통증군이 정상군에 비해 통계학적으로 유의하게 감소하였으며, 관절잡음군보다도 감소하여 통증군이 정상군과 관

A 21-year-old woman with a 4 cm enhancing cystic renal mass in the left moiety of a horseshoe kidney was treated through a retroperitoneal laparoscopic approach. The tumor was excised completely with cold scissors, and renal parenchyma suturing with a surgical bolster was done with Vicryl 2-0 sutures. Choosing the proper approach according to the location of the lesion and the surgeon's experience with both approaches are of importance in laparoscopic surgery in horseshoe kidney cases. A preoper

This prospective study aimed to evaluate whether Contralateral compensatory testicular hypertrophy (CTH) is valid as a predictive tool for a non-viable testis in children aged between 6 and 18 months, and whether CTH is affected by mini-puberty. Seventy-two testes from 60 boys aged between 6 and 18 months were categorized into three groups: 24 testes contralateral to surgically removed non-viable testes (NVTs), 24 testes contralateral to surgically corrected undescended testes (UDTs), and 24 tes
