A kidney stone patient goes home on a Wednesday afternoon after ureteroscopy with laser lithotripsy and a JJ stent, and by Wednesday night the bathroom has become the whole world. The urge to urinate arrives every ten minutes. He gets up, he goes, and almost nothing comes out. By 2 a.m. he has done this a dozen times and he is no longer tired — he is frightened. Something, he is fairly sure, has gone wrong. The office does not open for seven hours.
Pulled directly from PrepQ’s urology answer library, this is the question that lands, almost word for word, over and over: “After a cystoscopy, ureteroscopy and JJ stent, I need to pee constantly but only pass a few mls — is that the stent?”
Here is the answer PrepQ sends back by text, in seconds, at any hour: “Yes, needing to urinate constantly but only passing a small amount is a classic stent symptom, caused by the stent irritating the bladder and creating a frequent urge even when the bladder is nearly empty. It is uncomfortable but usually eases once the stent is removed. The medicines your doctor may prescribe can help. Call your urologist if you develop fever, chills, worsening pain, or you truly cannot urinate at all.”
Look at what that answer does and does not do. It names the mechanism — a stent tip sitting in the bladder, generating a false alarm the patient interprets as failure — so the symptom stops feeling like a catastrophe. Then it draws a hard line: fever, chills, worsening pain, or genuine inability to urinate are not “probably the stent,” and the patient is told to call. That line is not improvised by a language model. Every answer in the library is written by a board-certified physician and reviewed and approved by the subscribing practice’s own clinicians before a single patient ever sees it, and any practice can edit it to match its own post-ureteroscopy protocol. Questions the system has no approved answer for are routed to the office rather than guessed at, and anything that sounds urgent escalates to the practice or to 911 instead of being answered by AI. PrepQ operates under HIPAA safeguards, with a Business Associate Agreement available to each practice.
Stone disease is where urology feels this most sharply. A stent is temporary by design, which means the patient is living with a foreign body, a set of alarming-but-expected symptoms, and a removal date — and every one of those is a question that surfaces at night. Add the rest of the stone pathway (ureteral stent placement, ureteroscopy with laser lithotripsy, shockwave lithotripsy, stent removal) and a practice is fielding the same handful of after-hours calls week after week. PrepQ’s urology library spans more than 77 procedures and roughly 800 physician-written answers, delivered by text and by voice call, in English and Spanish, 24 hours a day.
The practical payoff is mundane and that is the point. A patient who understands stent frequency at 2 a.m. does not leave a voicemail that a nurse has to triage at 7:30, does not appear in an emergency department for a symptom that resolves at stent removal, and does not arrive at the stone-removal appointment convinced the first procedure failed. Practices should treat time-saved and cancellation figures as modeled estimates rather than measured outcomes — the mechanism, though, is not speculative: an answered question at midnight is a question that is not asked again at the front desk in the morning.
