URINARY SYSTEM 01

MESONEPHROS: This is a section of the mesonephros from a 41/2 week human embryo. Identify the INTRAEMBRYONIC COELOM (4), GLOMERULUS (5), MESONEPHRIC REDGE (6), AND MESONEPHRIC

DUCT AND MESONEPHRIC TUBULE.

URINARY SYSTEM 02

MESONEPHROS: This is a high power photomicrograph of the region shown in slide #1. Identify the same

structures.

URINARY SYSTEM 03

ABDOMINAL CAVITY: from a 51/2 week embryo. Recognize and identify the STOMACH (8), MIDGUT (7), DORSAL (4), and VENTRAL (9), PANCREAS, the MESONEPHROS (6), GENITAL RIGE (5), and the developing

METANEPHROS.

URINARY SYSTEM 04

10 WEEK FETAL KINEY: identify the SUPRARENAL GLAND RENAL CORTEX, RENAL PELVIS, MAJOR

CALYX and MINOR CALYX.

URINARY SYSTEM 05

Identify the suprarenal gland and metanephros at 9 weeks, 11 weeks and 13 weeks of development.

URINARY SYSTEM 06

RENAL AGENESIS: Recognize characteristic features of oligohydramnios and the small abdomen.

URINARY SYSTEM 07

This infant also exhibited the effects of oligohydramnios but not the distended abdomen associated with

polycystic kidney.

URINARY SYSTEM 08

Abdominal cavity from infant with renal agenesis.

URINARY SYSTEM 09

POLYCYSTIC KIDNEY: Note the small thorax, large abdomen and potters facies.

URINARY SYSTEM 10

Abdominal cavity of infant with polycystic kidney.

URINARY SYSTEM 11

Internal structure and cysts associated with infantile polycystic kidney.

URINARY SYSTEM 12

This is an example of juvenile polycystic kidney. Differentiate between infantile and juvenile polycystic kidney disease.

URINARY SYSTEM 13

This is an extreme example of juvenile polycystic kidney.

URINARY SYSTEM 14

"PANCAKE" KIDNEY. This defect arises due to midline fusion of the metanephric cap. Why doesn't this kidney

ascend?

URINARY SYSTEM 15

What is the location of the kidney shown in this radiogram?

URINARY SYSTEM 16

Recognize obstruction of the ureter.

URINARY SYSTEM 17

Identify hydronephros and hydroureter following ureter obstruction.

URINARY SYSTEM 18

Identify a ureteric diverticulum.

URINARY SYSTEM 19

Recognize ectopia vesicae. What structure is protruding through the anterior abdominal wall?

URINARY SYSTEM 20

Diagnose the condition known as "prune belly". What defects are usually associated with this abnormality?

URINARY SYSTEM 21

Recognize epispadius. How might this condition arise?
