A patient's experience at The GI Unit

A businessman was facing a ten-hour wait for treatment for excruciating abdominal pain when the hospital and its skilled clinical teams came to the rescue.

With no clear indication of when he might be seen, he made a crucial call through the London Urology unit which arranged for consultant surgeon Mr Leye Ajayi and his team to be ready for his arrival.

The patient had severe renal colic but within an hour of his consultation he was in the operating theatre and an hour later in the recovery bay after a successful procedure to remove urinary stones.

He says: “I was in the UK for a week but started getting pain in my abdomen so went to an A&E department at another hospital. I sat for five hours before being seen and, although I was sent me for a CT scan, they said they couldn’t do anything straight away and I had to wait another five hours.

The pain was terrible so I started looking for urologists online and found the hospital website which was impressive. I had a flight to catch the next evening so was eager to get seen as soon as possible and they unit was fantastic, organising an appointment with Mr Ajayi and making sure theatre space was free for an urgent appointment.

I didn’t expect to be seen an into theatre so quickly. I was told the cost and it was worth it. Painless is priceless. Everyone was very helpful and efficient, accommodat-ing my requests and sensitivities, giving me a halal meal option after the operation. I was delighted by this, it was nice.I’m extremely grateful they made space for me and I felt very secure and in good hands. The anaesthetist took extra care with me and painkillers for my recovery meant I had a great night’s sleep.

Mr Ajayi was professional and helpful at all times. In fact, everyone has been professional and accommodating to my needs and I am so pleased with the outcome.

Mr Leye Ajayi MD FRCS (Urol) Consultant Urological Surgeon comments: “The pa-tient was in pain and wanted immediate treatment which were able to facilitate. The staff on St Francis ward and in the theatre were fantastic with a prompt admission at the end of what had been a busy day for them.

Renal colic is a type of pain you get when urinary stones block part of your urinary tract. I was able to discuss treatment options with him and the operation was success-ful.
