Bladder stone secondary to prostatic urethral lift (PUL) for benign prostatic hyperplasia (BPH)

Bladder stone due to late clip migration after prostatic urethral lift procedure: A case report

BACKGROUND

Prostatic urethral lift (PUL) therapy is an alternative to minimally invasive and other surgeries in younger patients who want to preserve their sexual and ejaculatory functions, and in elderly male patients with benign prostatic hyperplasia who cannot be anesthetized because of the risk of anesthesia. The procedure can be performed as an outpatient and without anesthesia, and complications are few and temporary. In long-term follow-up, encrustations that require retreatment are rarely seen.

CASE SUMMARY

In our case, a 62-year-old prostate patient who had a PUL operation 8 years ago and had a stone on the PUL material near the bladder neck was treated. The patient's stone was removed by endoscopic cystolithotripsy using pneumatic fragmentation. Bipolar transurethral resection of the prostate was applied to the patient in the same session. After the patient's 7-year follow-up, the patient's complaints relapsed, and cystoscopy was performed again. In cystoscopy, stone formation adjacent to the wall was observed at the junction of the bladder neck to the left lateral wall. The stone was fragmented with a pneumatic lithotripter.

CONCLUSION

Placing clips too close to bladder neck in the PUL procedure may result in clip migration.

Giant bladder stone: A case report

Giant bladder stones are rare in younger patients. Herein, we report a case of acute renal failure in a 31-year-old male with a giant bladder stone. The patient presented with lower urinary tract symptoms and urinary retention with milky-white urine. An emergency suprapubic cystotomy was performed and an 11-cm oval, solid stone was removed. Post-operative creatinine levels progressively decreased to normal and the patient exhibited smooth urination and good recovery at follow-up. A comprehensive physical examination and thorough investigation of the patient's medical history are required during clinical evaluation, diagnosis and treatment, thus preventing misdiagnoses and ensuring prompt treatment.
