Volume of the normal prostate gland in polish boys, aged 1-17 years: Based on transabdominal ultrasound - Prospective study.

Background: Until now, there are no established norms for prostate size in children. Prostate volume during development has been analyzed in small study groups. In diagnostic imaging, transabdominal ultrasound and magnetic resonance imaging are used.

Urethroplasty with balloon catheterization in fetal lower urinary tract obstruction: observational study of 10 fetuses.

Objective: To present the preliminary outcomes of fetal urethroplasty using a coronary angioplasty balloon catheter in lower urinary tract obstruction (LUTO).

Methods: We included 10 consecutive male fetuses diagnosed with LUTO caused by presumed isolated posterior urethral valves (PUVs), who underwent urethroplasty with a balloon catheter in our center between 2015 and 2018. During urethroplasty, the fetal urethra was dilated using a balloon catheter (diameter, 0.

Early vesico-amniotic shunting - does it change the prognosis in fetal lower urinary tract obstruction diagnosed in the first trimester?

Objectives: The aim of the study was to assess the outcome of vesico-amniotic shunting performed before 16 weeks of pregnancy in fetuses with severe megacystis diagnosed in the first trimester of pregnancy.

Material And Methods: Between January 2008 and October 2012 severe megacystis with the bladder length > 15 mm was diagnosed in 17 fetuses. The procedure of early vesico-amniotic shunting (VAS) was offered to 8 patients with presumably isolated LUTO.

Ultrasound guided balloon catheterisation: a new method of fetal lower urinary tract obstruction management.

Objectives: Fetal lower urinary tract obstruction (LUTO), most often associated with presence of posterior urethral valves, poses high risk of perinatal mortality or postnatal renal failure. Looking for a method of causative treatment we have devel-oped a technique of fetal urethroplasty with a coronary angioplasty balloon catheter inserted under an ultrasonographic guidance via an 18-gauge needle introduced transabdominally to fetal bladder.

Material And Methods: We have used this procedure in three women with singleton pregnancies (two primiparas and one multipara, 32-35 years of age), diagnosed with fetal megacystis at 12-16 weeks of gestation.
