Case Summary

Our client, SG, attended her GP in December 2015, complaining of urinary symptoms, including leaking when she laughed or coughed. Her GP advised her to do pelvic floor exercises, and he referred her to the hospital to see a urogynaecological specialist.

SG was seen by the urogynaecologist at Eastbourne District General Hospital on 6 April 2016. The urogynaecologist thought that our client was suffering from mixed urge and stress incontinence and he made a referral for urodynamic studies in three months’ time. SG was diagnosed with a stage 1 cystocele and stage 1 rectocele. No demonstrable stress incontinence was found, but definite urethral hypermobility was noted, and the plan was for urodynamic studies to see if stress incontinence was demonstrated.

SG attended urodynamic studies on 27 May 2016, and these showed detrusor overactivity and urgency but importantly, did not show urodynamic stress incontinence. She was advised to start a prescription of Vesicare 5 mg to be increased to 10 mg later on for the next three months.

In November 2016 underwent uroflowmetry, which indicated a good detrusor muscle function. However, Vesicare had given her little benefit to her overactive bladder.

The urogynaecologist advised SG that there were two options for treating her incontinence; either tension-free vaginal tape (TVT) surgery or an autologous fascial sling. He informed SG that TVT had a very high success rate and that this was the best option for her. He informed SG that it was a straightforward procedure to be carried out under a general anaesthetic as a day case. SG signed a consent form on that day which described this procedure as “to treat SI” [stress incontinence].


SG underwent the TVT procedure at Eastbourne District General Hospital on 22 March 2017. SG found that she could not move her left leg after surgery. She initially thought this was due to the anaesthetic. SG became worried when things did not improve, and the Consultant came to review her. He could not diagnose the precise cause, and SG was therefore admitted to a urology ward.

On the urology ward, a size 12 catheter was inserted, and SG was noted to void 800ml with a residual bladder volume of 400mls. There was no improvement in her left leg power or function. SG was advised to mobilise and was referred to physiotherapy. Over the following days, she did regain some power in the left limb but remained unable to bend her knee or hip. She was injected with 300mg of hydrocortisone to ease the nerve inflammation in her leg.

SG underwent a diagnostic MRI scan of her pelvis on 27 March 2017. Excessive oedema within the adductor muscle compartment was noted. No evidence of a recent hip dislocation and degeneration in the lower spine was observed. A review by a radiologist with a sub-speciality interest for further detail was suggested.

Removal of TVT

On 28 March 2017, the TVT tape insertion was removed, and a cystoscopy was performed, and a retropubic TVT was inserted at the same time. The same surgeon performed this as previously, who noted following the removal of the TVT that SG had made a complete recovery. However, this was not the case.

In April 2017, SG still had pain in her left leg, which started at her hip and radiated down her leg. SG was therefore referred to a neurologist and thereafter to the pain clinic.

The neurologist saw SG on 2 May 2017 and noted, “following the revision she managed to walk and improved from the motor perspective, but she has been left with residual tingling and numbness of the left thigh resembling meralgia paraethetica”. The neurologist thought the diagnosis was possibly neuropraxia, which he hoped would resolve with time. However, he referred SG on for nerve conduction studies/EMG.

In May 2017, SG was referred for physiotherapy because she still suffered from severe pain in her left leg.

SG underwent several investigations in 2017, which included an MRI scan, which showed degenerative changes at L5-S1 with loss of disc height at L5-S1 with end plate degenerative change. There was a broad-based disc bulge at this level with bilateral recess narrowing and narrowing of the exit foramina. However, there was no definite evidence of nerve root compression, and there was no significant spinal canal stenosis.

SG attended pain management and physiotherapy between 7th September 2017 and 1st March 2018 and underwent hydrotherapy. However, this did not relieve her symptoms. She continued to suffer constant severe pain down her left leg with the sensation of sandpaper rubbing her skin below the left knee.

In April 2018, SG’s hip and thigh pain was such that she could not work for one week or drive. On 25th April 2018, whilst standing in the kitchen, SG felt urine gushing down her legs this being the second occasion on which this had occurred in the past month. Her incontinence was ongoing and she suffered leaks and urgency daily. The pain would interrupt her sleep such that she became chronically tired and this, together with her incontinence, impaired her mood, her capacity for work and her family life.

Civil Case

SG instructed Nicholas Leahy, medical negligence specialist, to pursue a civil claim against East Sussex Healthcare NHS Trust.

Supportive expert evidence was obtained from a Consultant Urogynaecologist (on breach of duty and causation) and a leading neurologist (on causation). The experts thought that SG’s symptoms were incorrectly diagnosed as stress urinary incontinence rather than detrusor overactivity and that, therefore, SG had been incorrectly advised to undergo TVT surgery. The correct treatment in SG’s case would have been medication, weight loss and/or Botox, notwithstanding her previous lack of response to Vesicare medication.

Further, the medical experts instructed by Osbornes were of the view that the performance of the surgery on 22nd March 2017 was substandard in that SG was positioned with such force in the lithotomy position and/or operated on in such a manner as to cause a permanent nerve injury to the left L3/4 nerve roots as they come away from the spinal cord.

Expert evidence was obtained commenting on causation. This enabled SG to argue that had she been treated correctly with medication for her overactive bladder, she would likely have been offered Botox treatment at 3-6 monthly intervals. It was, therefore, more likely than not that her overactive bladder would have been controlled, and she would have been continent of urine. Naturally, she also would have avoided the initial surgery and the revision surgery, which took place in March 2017.


A Letter of Claim was sent to the Defendant Trust in May 2019. However, liability was denied. The Defendant maintained that SG had been correctly diagnosed and that surgery was the appropriate option but that she had simply suffered a recognised complication of such surgery.

The parties were unable to reach any agreement, and so in March 2020 court proceedings were issued against the Defendant hospital trust. Laura Begley of 9 Gough Chambers, a barrister, was instructed to advise SG.

The court proceedings were served against the Defendant, together with Condition and Prognosis evidence which had been obtained from a Consultant Urogynaecologist and a Consultant Neurologist. However, the Defendant maintained their denial of liability, serving a complete Defence to the claim in April 2021 (various extensions of time had to be agreed due to the SARS-COV-2 pandemic).

SG’s case was then listed for a Costs and Case Management Conference. However, shortly before this was due to take place, and following a negotiation period, the parties agreed to a five-figure settlement of SG’s case.

The settlement will enable SG to access continued care with a specialist in urogynecology. SG can now obtain a trial of anticholinergic therapy in conjunction with bladder training from a specialist continence nurse to treat her urinary urgency and urge incontinence. She will also be able to access supervised pelvic floor therapy.

In relation to the ongoing pain in her left leg, the settlement will enable SG to undergo multidisciplinary pain management treatment. The medical management will include physical treatment, injection, talking, and pharmacological therapies, all supervised by a Consultant Neurologist.

Nicholas Leahy, Solicitor in the Clinical Negligence Department at Osbornes said:

This was a very difficult claim in which complex issues relating to breach of duty and causation remained in dispute. However, with the help of quality expert evidence from some of the country’s leading medical practitioners, I am very pleased that we obtained a positive result for SG, who can now move on with her life and access the treatment she requires”.
