Enlarged Prostate, Uremia, and Kidney Failure: A Patient Case

This is a personal account by Nigel Shaw (Xialla CEO and inventor of the device). Over several years, typical urinary symptoms from an enlarged prostate progressed to kidney failure from chronic urinary obstruction. The effects included fatigue, sleep disturbance, cognitive slowing, and changes in how he experienced daily life. The account is included here because obstructive uropathy from BPH is under-recognized, and early evaluation can prevent irreversible kidney damage.

It is one person’s medical history, not a treatment recommendation. Decisions about testing and surgery belong with your physician.

How BPH can damage the kidneys

Benign prostatic hyperplasia (BPH) is common with age. The prostate surrounds the urethra just below the bladder. As it enlarges, urine flow can be obstructed.

When obstruction is chronic, pressure transmits backward into the bladder and then the kidneys (obstructive uropathy). The kidneys can swell (hydronephrosis) and lose filtering capacity. In some men this produces post-renal kidney failure — damage that originates from blockage downstream rather than from primary kidney disease.

Significant kidney damage is not the most common BPH complication, but it does occur when lower urinary tract symptoms are ignored or left untreated for years. See Mayo Clinic and AHRQ PSNet references below.

Uremia and systemic effects

As kidney function declines, waste products accumulate in the blood (uremia). Effects can be subtle at first.

In this case they included:

• Profound, persistent fatigue
• Sleep disturbance and muscle cramps
• Cognitive slowing and difficulty with focus or complex tasks
• Changes in social perception, emotional engagement, and judgment

Uremic toxins can affect brain function (Viggiano et al., 2020). What felt like gradual “fog” had a physiological cause: waste the kidneys could no longer clear. These changes were not simply “getting older” or stress.

Symptoms to track and discuss

Many men adapt to urinary changes and assume they are normal aging. Patterns that deserve medical attention — especially when they worsen or occur with systemic symptoms — include:

• Urinary — weaker stream, hesitancy, intermittency, incomplete emptying, straining, frequency (especially at night), or urgency
• Possible retention or severe obstruction — marked worsening, or any episode of inability to urinate
• Systemic symptoms alongside urinary change — unusual fatigue, brain fog, muscle cramps, disrupted sleep, or declining mental clarity

If progressive urinary symptoms occur together with fatigue or cognitive change, ask whether kidney function and bladder emptying should be evaluated.

Tests clinicians often use

These are not routine for every man with mild urinary symptoms. They are commonly used when symptoms are significant, worsening, or when other risk factors are present:

• Blood tests — serum creatinine and blood urea nitrogen (BUN); estimated glomerular filtration rate (eGFR) calculated from creatinine. An eGFR below 60 for three months or more can indicate chronic kidney disease and often prompts further investigation.
• Post-void residual (PVR) — urine left in the bladder after voiding, usually measured by bladder scanner or ultrasound. Persistently high PVR suggests poor emptying and possible back-pressure on the kidneys.
• Renal and bladder ultrasound — looks for hydronephrosis and helps assess residual urine and prostate size when blood tests or PVR are concerning.

American Urological Association guidance does not recommend routine kidney-function screening for every man with lower urinary tract symptoms; targeted testing is appropriate when concerning features are present.

A practical question for a visit: “Given my urinary symptoms and fatigue/brain fog, would it be reasonable to check kidney function with bloodwork and measure post-void residual?” Referral to a urologist is a common next step when results are abnormal or symptoms persist.

TURP and recovery

After evaluation, Nigel underwent transurethral resection of the prostate (TURP) to remove obstructing tissue. Kidney function improved substantially afterward. Uremic symptoms that had built for years began to resolve: energy, mental clarity, sleep, and social engagement returned toward baseline.

Diagnosis had been delayed in part by earlier misreading of symptoms. Persistent lower urinary tract symptoms are not automatically “just aging.”

Points this case illustrates

• Do not ignore persistent lower urinary tract symptoms; early evaluation can prevent downstream kidney damage.
• Ask that blood tests include kidney function and that abnormal results are reviewed carefully.
• After age 50, routine men’s health visits should include discussion of urinary symptoms (and PSA where appropriate).
• Prostate obstruction, kidney function, and systemic vitality are linked when outflow is chronically impaired.
• Relief of obstruction can reverse a substantial part of the uremic burden when damage is not yet permanent.

Prostate treatment and sexual function

BPH treatment and prostate surgery can change erectile function and ejaculation. Men navigating sexual changes after prostate procedures may find these useful: Orgasm and Ejaculation After Prostate Surgery and Supporting Sexual Function After Prostate Surgery.
