Pathophysiological effect of bladder outlet obstruction on the urothelium

Area of Science:

• Urology
• Cell Biology
• Physiology

Background:

• Bladder outlet obstruction (BOO) causes lower urinary tract symptoms, impacting quality of life.
• Increasing BOO prevalence burdens healthcare systems, necessitating effective management strategies.
• The pathophysiology of BOO-induced symptoms is multifactorial and not fully understood.

Purpose of the Study:

• To review the role of the urothelium in bladder outlet obstruction.
• To examine urothelial ultrastructure, barrier, and transport functions in BOO.
• To investigate the impact of urothelial changes on the sensory web and afferent signaling.

Main Methods:

• Literature review focusing on urothelial changes in BOO.
• Analysis of studies on urothelial ultrastructure and barrier function.
• Examination of research on urothelial transport and sensory signaling in BOO models.

Main Results:

• Urothelium plays a key role beyond its barrier function in BOO.
• BOO induces alterations in urothelial ultrastructure and barrier integrity.
• Urothelial dysfunction affects blood-urine transport and sensory web modulation.

Conclusions:

• The urothelium is a critical factor in BOO pathophysiology.
• Understanding urothelial adjustments offers potential therapeutic targets for BOO symptoms.
• Further research into urothelial function is vital for improving BOO management.
