Urodynamic Studies: Uroflowmetry

395
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Imaging Studies VI: Voiding Cystourethrography and Cystography

96
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

35
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Summary

Parametrectomy during endometriosis surgery significantly increases surgical complications, including voiding dysfunction and major adverse events. This highlights the importance of careful surgical planning when parametrial involvement is present.

Area of Science:

  • Gynecologic surgery
  • Endometriosis research
  • Surgical oncology

Background:

  • Parametrial involvement (PI) in endometriosis is often poorly defined, leading to underestimation of its surgical impact.
  • Surgical excision of deep pelvic endometriosis requires precise definition of anatomical involvement.

Purpose of the Study:

  • To assess surgical complications associated with parametrectomy during endometriosis surgery.
  • To compare complication rates of parametrectomy with excision of other deep pelvic endometriotic locations.

Main Methods:

  • Retrospective analysis of 753 patients undergoing surgery for deep pelvic endometriosis (2013-2018).
  • Surgical complications assessed based on parametrectomy, extent of resection (colpectomy, torus, utero-sacral ligaments, rectal resection), and graded using Clavien-Dindo classification (CDC).
  • Voiding dysfunction defined as need for self-catheterization ≥1 month.

Main Results:

  • Patients with PI (37.8%) had higher ASRM scores and more extensive surgery.
  • Higher rates of voiding dysfunction (17.5% vs 8.98%) and postoperative complications (44.6% vs 24.6%) in patients with PI.
  • Parametrectomy significantly increased adverse postoperative events, particularly in extensive resections involving torus, utero-sacral ligaments, parametrium, and vagina (aOR=37.28).

Conclusions:

  • Parametrectomy during endometriosis surgery is associated with significantly increased postoperative complications.
  • Surgical complexity and extent, especially involving the parametrium, are strongly linked to adverse outcomes.
