Diabetic bladder dysfunction: current translational knowledge.

Area of Science:

• Urology
• Endocrinology
• Diabetology

Background:

• Diabetes mellitus is a metabolic disorder with serious complications, including common lower urinary tract issues.
• Diabetic cystopathy, or diabetic bladder dysfunction, is a frequent and bothersome complication.
• This review focuses on current translational knowledge regarding diabetic bladder dysfunction.

Purpose of the Study:

• To review the current translational knowledge of diabetic bladder dysfunction.
• To provide data and perspective for future research directions in diabetic bladder dysfunction.

Main Methods:

• A comprehensive search of the English literature was conducted via PubMed.
• Key search terms included "diabetes" and "bladder dysfunction" or "cystopathy."

Main Results:

• Diabetic bladder dysfunction manifests as both voiding problems (poor emptying, overflow incontinence) and storage issues (urgency, urge incontinence).
• Experimental evidence in animal models shows a temporal effect: early diabetes leads to compensated bladder function, while late stages result in decompensated function.
• Mechanisms like polyuria, hyperglycemia, oxidative stress, autonomic neuropathy, and bladder muscle decompensation contribute to the clinical and experimental findings.

Conclusions:

• Diabetic bladder dysfunction exhibits time-dependent storage and emptying problems.
• Identifying the mechanistic pathways underlying these temporal changes is crucial for developing therapeutic interventions.
