Urethral Dilatation Treatment in Singapore

Your urologist uses specially designed instruments to gradually increase the diameter of the narrowed area. There are two main approaches.

The first uses graduated dilators: smooth, tapered instruments that increase in size. Your urologist passes them through the urethra one at a time, starting with the smallest and progressing to larger sizes. Each dilator gently stretches the scar tissue a little further, widening the passageway in controlled increments.

The second uses a balloon catheter system. A thin catheter with a deflated balloon tip is guided into the narrowed segment. Once positioned, the balloon is inflated with fluid, applying even, outward pressure against the scar tissue to stretch the stricture open from within.

Dilatation creates a controlled disruption of the fibrotic scar tissue (the dense, inelastic collagen fibres that form the stricture). The mechanical force breaks apart these fibres, allowing the urethral lumen (the inner channel of the tube) to widen and re-establish a more functional calibre. Think of it like loosening a tightly knotted rope: the knot does not disappear, but it becomes loose enough to allow movement again.

Dilatation does not remove the scar tissue entirely. It reshapes and stretches the narrowed area to improve urine passage. The body’s healing response following this controlled tissue disruption influences how long the improvement lasts, which is why follow-up monitoring with your urologist remains important.

The type of anaesthesia depends on the complexity and location of your stricture, your medical history, and your personal comfort level.

For straightforward cases, local anaesthesia may be sufficient. A topical anaesthetic gel is applied directly into the urethra to numb the area before any instruments are introduced. This allows you to remain awake and typically involves minimal recovery time.

For more complex strictures, or for patients who feel significant anxiety, sedation or general anaesthesia may be recommended. Sedation keeps you in a relaxed, semi-conscious state; general anaesthesia means you will be fully asleep throughout.

The choice of anaesthetic approach is a clinical decision made collaboratively between you and your specialist. Dr Azhari evaluates each patient’s specific urological condition to determine an appropriate approach tailored to their comfort and clinical needs.

Optical urethrotomy (also known as internal urethrotomy) uses a small blade or laser, passed through a cystoscope, to make a precise incision through the stricture. This releases the tight band of scar tissue and allows the urethra to widen, rather than stretching it open.

Both urethral dilatation and optical urethrotomy are often considered for short, non-complex strictures, particularly those being treated for the first time. The choice between them depends on the specific characteristics of your stricture, its location, and your urologist’s clinical judgement. Learn more about optical urethrotomy as an alternative approach.

For longer, recurrent, or more complex strictures, your urologist may recommend urethroplasty (an open surgical procedure to reconstruct the affected segment of the urethra). This may involve removing the scarred section and reconnecting the healthy ends, or using a tissue graft to widen the narrowed area.

Urethroplasty represents a different level of intervention within a comprehensive stricture management pathway. It is typically considered for cases where less invasive approaches have not provided lasting improvement, or where stricture characteristics make dilatation or urethrotomy less likely to be appropriate.

Dr Azhari works with each patient to determine the most clinically appropriate treatment strategy based on a thorough assessment of the stricture and the individual’s overall health.

A specialist urological environment ensures access to appropriate instruments, imaging guidance (such as cystoscopy or fluoroscopy), and sterile protocols that collectively reduce the likelihood of complications.

Adherence to established urological protocols, including proper patient selection, careful instrument handling, and thorough post-procedural monitoring, forms the foundation of safe practice. Dr Azhari follows these established clinical protocols to support patient safety and care.

Informed consent is a vital step in this process. Before your procedure, your urologist will discuss the specific risks relevant to your case, answer your questions thoroughly, and ensure you feel confident in your understanding of what lies ahead.
