Dr Christopher Jayne | Eliminating Serious Surgical Complications with the Novel C-Clamp Technique

Dec 15, 2023 | Medical & Health Sciences

Surgical procedures to treat urinary incontinence come with risks, and complications can include injury to the bladder, urethra, intestines, haemorrhage (bleeding), and urinary retention. Dr Christopher Jayne, founder of Greater Houston Urogyn in Houston, Texas, specialises in urogynecology and reconstructive pelvic surgery and is an expert in the surgical management of stress urinary incontinence in women. He works tirelessly to optimise the safety and efficacy of these surgical procedures by pioneering novel surgical techniques.

A Very Common Problem

Urinary incontinence is a common problem in women. It affects around half of all women at some point in their lives. Unsurprisingly, it can significantly affect their physical and mental health, impacting many aspects of their daily lives. The most common type of urinary incontinence is stress urinary incontinence (SUI). Women experience urine leaks when the bladder is under pressure, for example, when they laugh, cough or sneeze. In more severe cases, it can happen even when walking around or standing up from a seated position.

SUI occurs due to damage or weakening of the pelvic floor muscles and connective tissue, resulting in loss of pelvic floor support and distortion of normal pelvic anatomy. Specifically, the urethra (the tube connecting the bladder to the outside world) struggles to stay closed due to these changes and stressurinary incontinence results. While childbirth is the leading cause of SUI, other causes include ageing, smoking, obesity, previous pelvic surgery, and connective tissue disorders.

Non-surgical treatments can include dietary and lifestyle modifications, health optimisation, weight loss, and pelvic floor physiotherapy. When these conservative treatments are not effective, surgery is the ultimate treatment.

Support for the Urethra

Synthetic mesh mid-urethral slings are the consensus gold standard surgical treatment for SUI with urethral hypermobility in women. Dr Jayne explains that during this operation, a thin strip of polypropylene mesh is implanted under the mid urethra via a small incision in the vagina and either two small  incisions in the suprapubic region of the lower abdomen for a retropubic sling or two  small incisions in the inguinal regions lateral to the clitoris for a transobturator sling. The mesh acts like a  hammock, correcting the loss of support of the mid urethra, reestablishing the continence mechanism and thus, preventing SUI.

Dr Jayne’s work focuses on the bottom-up retropubic mid-urethral sling. The retropubic approach was the first synthetic mesh mid-urethral sling, described in 1996. Although this approach is associated with the highest success rates in treating SUI, it is associated with injury to the bladder, urethra, and intestines when placing the sling. It is also associated with incomplete bladder emptying and mesh exposure in the vagina after placement. In an attempt to mitigate these complications, techniques to avoid the retropubic space were developed for placing the sling. Unfortunately, none of these techniques have eliminated complications, and none are as effective in treating SUI as the retropubic approach.

Dr Jayne notes that the evidence in the medical literature suggests that retropubic synthetic mesh mid-urethral slings are more effective and less expensive over an individual’s lifetime than alternative techniques. He argues that, unfortunately, many surgeons choose alternative sling placement options, with lower cure rates that are more likely to require repeat surgery later, due to the perceived decreased risk of bladder injury and other complications.

The C-Clamp Technique

Dr Jayne developed the C-clamp technique in 2009 to address the critical factors believed to contribute to bladder and urethral injuries, as well as urinary retention rates, using the bottom-up retropubic approach. His goal was to eliminate these complications with a standardised, reproducible technique. He feels that if accomplished, the C-clamp technique could become the standard of care for implanting bottom-up retropubic slings and be universally adopted by the surgical community. If his success was reproducible and adopted, the best approach (retropubic) would be used on all patients.

The technique involves mobilising vital structures such as the vagina, bladder, and urethra to place and adjust the sling at the mid-urethra eliminating the risk of complications. The name is derived from the shape the surgeon’s hand makes to guide the trochar (a medical device used in the surgery) through the retropubic space when placing the sling.

He explains that despite the synthetic mesh mid-urethral sling being the most published gynaecological surgery in the history of Western medicine, there were no publications that describe a standardised approach and technique, and no study reporting zero complications. To overcome this, Dr Jayne published his simple and reproducible step-by-step instructions for the C-clamp technique.

Eliminating Bladder Injury

In 2023, Dr Jayne’s publication reported no urethral or bladder injury using the C-clamp technique. His team searched all the medical records of his patients who had undergone the bottom-up retropubic synthetic mesh mid-urethral sling using the C-clamp technique between April 2012 and June 2022. Two hundred and one cases were identified and carefully reviewed.  Regardless of a number of factors, such as age, weight, prior gynaecological surgery or C-section, the C-clamp technique resulted in a bladder or urethral injury rate of an impressive 0%. Anecdotally, he reports no patient in his series had an intestinal injury or post-operative urinary retention. He adds that the cases reviewed fairly represented women requiring surgical treatment for SUI.

Dr Jayne concluded that regardless of a number of factors, such as age, weight, prior gynaecological surgery or C-section, the C-clamp technique resulted in no complications  and this is why he feels the C-clamp technique should be adopted as the technique of choice for implanting a retropubic synthetic mesh mid-urethral sling. Since the available data suggest that the retropubic approach has better long-term efficacy and is more cost-effective than other approaches, he hopes to remove deterrents to its use with the utilisation of the C-clamp technique.

The Future of the C-Clamp Technique

Dr Jayne notes some limitations of this work, the main ones being that most of the slings used were from one particular manufacturer and that he was the only implanting surgeon. He suggests that further evaluation of the C-clamp technique with different surgeons and other brands of retropubic slings is required. He adds that long-term data about outcomes following the procedure could also help support his novel technique as the gold standard. If these data support his findings, he feels the C-clamp technique could become the standard practice for bottom-up retropubic synthetic mesh mid-urethral sling placement.

Eliminating the risk of bladder and urethral injury during  sling placement to treat SUI brings peace of mind to both patient and surgeon. Dr Jayne’s pioneering work certainly offers new hopes for treating this widespread condition, which can severely impact the everyday lives of women all over the world.

Professor Toni Miles | Why Understanding Bereavement Matters

Professor Toni Miles has dedicated her research efforts to measuring bereavement and its impact on population health. Individual experience with bereavement is commonplace, but we know little about its impact on society when there is an instantaneous experience by a large number of individuals, i.e., mass bereavement. To measure its occurrence, her research with colleagues first confirmed that bereavement can be effectively measured in population surveys. Professor Miles argues that we should use such approaches to deliver interventions aiming to reduce the negative consequences of bereavement on individuals. By measuring bereavement in communities, these data become a cost-effective way to increase resilience, reduce demands on healthcare systems, and enhance public safety.

Dr Omar Islam | Portable Magnetic Resonance Imaging: An Important Innovation

Imaging technologies are vital in modern medicine and have revolutionised how clinicians make diagnoses and monitor disease progression. However, the necessary equipment – such as a scanner for magnetic resonance imaging (MRI) – is very large and expensive, requiring patients to go to the scanner rather than receiving scans as bedside care. This takes up valuable staff time and resources, and can present further risks to patients. Dr Omar Islam from Queen’s University and Drs Aditya Bharatha and Amy Lin from the University of Toronto are showing how portable MRI scanners may offer a viable alternative that benefits patients and healthcare systems.

Professor Danny Reinberg – Dr Gary LeRoy | Confronting a Rare and Deadly Cancer in Children

A diagnosis of cancer is never welcome but is particularly devastating when a child is found to have diffuse intrinsic pontine gliomas – a rare but particularly aggressive and treatment-resistant malignancy in the brain. In this article, we focus on the contributions of Professor Danny Reinberg and Dr Gary LeRoy at the University of Miami-Miller School of Medicine to understanding what makes these tumours so dangerous and, importantly, to developing much-needed approaches to improve the outcomes for these children.
