[Urodynamic study on primipara and bipara after parturition].

Area of Science:

• Urology
• Gynecology
• Obstetrics

Background:

• Postpartum recovery involves significant physiological changes, including those affecting lower urinary tract function.
• Understanding bladder function changes after childbirth is crucial for assessing maternal health and well-being.

Purpose of the Study:

• To investigate and compare bladder function in primipara (first-time mothers) and bipara (second-time mothers) within one week after delivery using urodynamic studies.
• To evaluate specific urodynamic parameters such as functional bladder volume, urethral pressure, and voiding ability.

Main Methods:

• Urodynamic investigations were conducted on 36 primipara and 12 bipara volunteers, adhering to International Continence Society (ICS) guidelines.
• A control group of 14 nulliparous women with normal lower urinary tract function was included for comparison.

Main Results:

• Both primipara and bipara exhibited lower functional bladder volume (FBV) and normal desire cytometric capacity (NDCC) compared to controls.
• Static urethral closure pressure was significantly higher in postpartum women than in controls, though no significant difference was found between primipara and bipara.
• Functional urethral length showed a significant difference between primipara and bipara.

Conclusions:

• Bladders of primipara and bipara are sensitive shortly after delivery, with increased static urethral pressure parameters.
• Despite these changes, voiding ability remains normal in both groups.
• No significant differences in key urodynamic parameters were observed between primipara and bipara within one week postpartum.
