Clinical anatomy of uretheric constraints: A systematic review

doi:10.37118/ijdr.18571.05.2020

Abstract

Introduction: The ureter is a channel responsible for carrying urine to the urinary bladder, through peristalsis and contractions, however, this channel can be affected by three types of constrictions, at the junction of the ureter with the renal pelvis called the ureteropelvic, from the edge of the pelvis to the passage of the iliac blood vessels called the abdominopelvic and at the intersection of the external iliac artery and the bladder wall called the vesicoureteral. These points, then, are relevant for clinical analysis, since they are the cause of several pathologies such as urinary incontinence, intrinsic urinary sphincter dysfunction, and obstruction by kidney stones. Objective: This study aims to carry out a systematic review study of the three points of ureteral contractions. Methodology: The present proposed literature review on the anatomical points of ureteric constrictions, carried out between August and September 2018. Result: It was found that the most widely used medications for pain relief are antispasmodics, non-opioid analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs) and narcotics. Conclusion: It is concluded that, for a better diagnosis, tests such as uroflowmetry, voiding urethrocystography, cystoscopy, and ultrasound are used

The ureter is a channel responsible for carrying urine to the urinary bladder, through peristalsis and contractions, this channel can be affected by three types of constrictions, at the junction of the ureter with the renal pelvis called the ureteropelvic, from the edge of the pelvis to the passage of the iliac blood vessels called the abdominopelvic and at the intersection of the external iliac artery and the bladder wall called the vesicoureteral
Constriction can be caused by several pathologies, such as kidney stones, urinary tract infections, congenital stenosis, cancer, STIs (Sexually Transmitted Infections), trauma or urethral injuries
The complications when having a urethral narrowing are that the bladder muscle becomes overloaded, having to make a greater effort to generate urinary flow in order to overcome the region of stenosis

Summary

INTRODUCTION

Constriction can be caused by several pathologies, such as kidney stones, urinary tract infections, congenital stenosis, cancer, STIs (Sexually Transmitted Infections), trauma or urethral injuries. The complications when having a urethral narrowing are that the bladder muscle becomes overloaded, having to make a greater effort to generate urinary flow in order to overcome the region of stenosis. The exams to evaluate the urinary tract and detect urethral constriction are intravenous urography, imaging exams such as tomography and excretory urography (Leão, 2002). The treatment for ureteral constriction can be prophylactic antibiotic therapy, pyeloplasty, which is the dissection of the proximal ureter and pelves, for the reconstruction of urinary drainage and ureteral dilation with a balloon to increase the internal diameter of the urethral canal (Hachul, 2004). Based on the text presented, the study aimed to conduct a systematic review study of the three points of ureteral constriction
