Urinary Tract Calculi VI: Surgical Management

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Background:

Transurethral bladder tumour resection (TURBT) is a key procedure for bladder cancer management.
Assessing resection quality, specifically detrusor muscle presence, is crucial for accurate staging and predicting recurrence.
Surgeon experience is a potential factor influencing TURBT quality.

Purpose of the Study:

To evaluate the quality of transurethral bladder tumour resection (TURBT) based on detrusor muscle presence.
To investigate the association between surgeon experience and the quality of TURBT specimens.

Main Methods:

A retrospective analysis of 640 TURBT procedures was conducted.
Data included patient characteristics, procedure details, surgeon category, and pathological findings.
Logistic regression models were used to assess the association between surgeon experience and detrusor muscle presence.

Main Results:

Supervised junior residents achieved detrusor muscle presence in 73% of TURBT specimens.
Consultants achieved detrusor muscle presence in 83% of TURBT specimens.
Junior residents had significantly lower odds of achieving detrusor muscle presence (OR = 0.4).

Conclusions:

Surgical experience is a significant predictor of achieving adequate detrusor muscle in TURBT specimens.
Supervised junior residents demonstrated lower rates of detrusor muscle presence compared to consultants.
These findings highlight the importance of experience in optimizing TURBT quality.
