PURPOSE: To compare the accuracy and precision of orchidometer ultrasonographic (US) measurements testicular volume in a canine model. MATERIALS AND METHODS: Volume 18 testes were obtained by using Prader Rochester orchidometers. Testes scanned with two linear-array US transducers imaging frequencies 6–13 MHz 5–10 MHz. For each transducer, volumes calculated three formulas: length (L) × width (W) height (H) 0.52, L W2 W H 0.71. weighed following bilateral orchiectomies. True was determined...

Laparoscopy was done in 104 consecutive patients with 106 impalpable testes. Three clinical presentations were identified and the value of laparoscopy each analyzed. 1) For unilateral contralateral normal testes laparoscopic identification testicular absence made 27% cases intra-abdominal found 16%. Therefore, 43% cases. 2) bilateral undescended (1 or both impalpable) diagnostic 75% (17% had blind-ending spermatic vessels above internal ring 58% testes). 3) previous negative inguinal...

GAS United States, however, lagged behind practice acceptance. Two American pioneers care patients undergoing gender-affirmation therapies were Elmer Belt Harry Benjamin. How they became dedicated to establishing a new standard for States is less clear. Our goal was describe how Benjamin created US, context their time,...
Background. Vesicoureteral reflux (VUR) is the most commonly inherited disease of genitourinary tract. Although majority evidence supports a genetic cause, tendency for this condition to spontaneously improve over time has made it difficult determine actual mode transmission. We report incidence VUR in siblings multiple gestation births and first compare relative between identical fraternal twins. Methods. A database consisting all radionuclide cystograms voiding cystourethrograms performed...
