A Welsh Doctor, Sir Hans Sloane, and the disappearing catheter

By Alun Withey

Editor’s note: Alun would like to warn all readers that this post contains some graphic description of a particularly uncomfortable surgical technique…

In 1720, Dr. Alban Thomas was something of a high-flyer. The son of a Pembrokeshire cleric and poet, Alban first matriculated from Oxford in 1708, became librarian of the Ashmolean museum, assistant secretary of the Royal Society and, if that wasn’t enough, obtained his doctorate in medicine from Aberdeen in 1719. At a time when Wales was still a largely rural country, with no medical institutions of its own and fairly poor transport and road infrastructures, these were exceptional achievements for a boy from Newcastle Emlyn.

Also unusual was that Alban appears to have returned to Wales to set up his medical practice; many Welsh practitioners who had trained in Oxford or London chose not to return, choosing the potentially more lucrative market of the larger English towns. Nonetheless, especially in and around the growing Welsh towns, there was still a relatively wealthy Welsh elite to cater for and some, like Alban, positioned themselves to serve the denizens of large estates and houses.

It is clear, though, that Alban still had connections. One of his correspondents was no less a luminary than Sir Hans Sloane, the Irish physician to the fashionable and, indeed, the royal and, later, president of the Royal Society. Surviving letters from Alban Thomas to Sloane suggest that theirs was a fairly regular correspondence, with Sloane acting in an advisory role for particular cases. It is one particular case that interests us here.

In November 1738, Alban Thomas wrote to Sloane regarding a patient, Sir Thomas Knolles of Wenallt, Pembrokeshire, who was causing him concern. Knolles, although “a person of great worth, candour and humanity” was also

a person of very gross habit, of body an unusual size and make and about 20 stone weight with an appetite to his meat but very moderate in his drinking.

Knolles enjoyed exercise but, due to his size, this was often done on horseback.

At some stage, Knolles had become ‘dropsicall’ and suffered from swollen legs. The doctor used a combination of diuretics and tight, laced stockings to countermand this with, he reported, some success as Knolles returned to health, requiring only the odd purge as a ‘spring clean’. About four years previously however Knolles had begun to complain of a swelling in his scrotum, which Alban Thomas assumed to be hydrocele–a condition causing grossly swollen testicles (sometimes treated by injecting port wine into the testicles). After drawing off “about a quart of limpid serum” from the stoic Knolles’ testicles followed by the application of a dressing, and strict recovery routines, the doctor hoped that he had cured the condition for good. This proved to be premature.

When Knolles began to complain sometimes of not being able to pass urine at all, at others a few drops and occasionally losing his bladder control entirely, he took it upon himself to get a second opinion from an unnamed doctor in nearby Haverfordwest. This physician prescribed a ‘Turbith vomit’ which wrought well and even caused Knolles to void a stone about the size of a kidney bean. Rather than being put off by this occurrence, Knolles was encouraged and began to pester Dr Thomas to give him more of these treatments. Unimpressed and undeterred, Thomas decided on a more proactive course. After putting Knolles on a course of diuretic medicines, liquors and balsams for a week he brought in to his consulting room. What happened next highlights the particular horrors of early modern surgery.

When Knolles arrived, Dr Thomas first applied a Turbith vomit, hoping that “so rugged a medicine” would clear the blockage without the need for more invasive procedures. It didn’t. In fact, the symptoms grew worse. It was at this point that Dr Thomas reached for his catheter and introduced it into the unfortunate Sir Thomas’s member. Expecting some resistance, he was surprised to find that the catheter went in without resistance.

On the contrary it seemed to force itself out of my fingers after passing the neck of the bladder as if it was sucked in, which I thought was owing to the pressure of his belly, the crooked end was now upward.

Yes, you read it right. The catheter was ‘sucked’ out of the doctors fingers and upwards further into the bladder! Now, any male readers may want to cross their legs!

In an attempt to probe for the stone that he feared was lurking in the bladder, and to release some water, Dr Thomas decided to turn the catheter around. At this point, the poor patient “cryed out with some violence…TAKE IT OUT I CAN BEAR IT NO LONGER”. Happily for Knolles the catheter came out “with as much ease as it went in without one drop through it or immediately after it”.

Three months later, the patient was still suffering, with the addition of great pain, defying all attempts for his relief. Despite being a “hail, hearty man having good lungs but lyable to hoarseness” and the occasional cold, Alban Thomas perceived him to be a healthy man. His efforts to treat Knolles had so far failed and he appealed to the eminent Sloane to help him “form a right judgement in this case”.

And so we leave the story there. What happened to Knolles is unclear, but the pain of his condition can only have been matched by the pain of his treatment. Suffering a succession of violent vomits, pills, electuaries and, finally, a wandering catheter, it is almost amazing to think that he ever went near Dr Alban Thomas again. Such (uncomfortable) cases remind us of the situation facing patients in the early modern period. For some the decision to see a doctor must have been a balancing act between bearing their illness or facing treatment.
