We present a case of a ureteropyeloscopy with holmium laser lithotripsy for a 5mm distal ureteral calculus that was complicated by perinephric hemorrhage despite utilization of a ureteral access sheath and the absence of any bleeding disorders. Conservative management was elected and the patient did not require transfusion of blood products. We believe this is the first case of perinephric hemo...

A 23-year-old female had bilateral ureteral stents placed due to bilateral renal stones and hydronephrosis. The bilateral ureteral stents were changed every 3 months. A kidney ureter bladder (KUB) film showed left encrustation along the ureteral stent thus necessitating removal; however, the ureteral stent could not be removed cystoscopically. The ureteral stent was, therefore, extracted using ...

Benign prostatic hyperplasia (BPH) requiring surgery has become a significant public health challenge in recent times as a result of the increase in population longevity. Furthermore, most of these patients have associated comorbidities and treatments, particularly with antiplatelet and anticoagulant drugs causing limitations in the surgical options such as open simple prostatectomy, or even tr...

Percutaneous holmium yttrium aluminum garnet (Ho:YAG) laser ablation of the nucleus pulposus of thoracolumbar discs in dogs as a prophylactic procedure for prevention of catastrophic intervertebral disc protrusion/extrusion has been utilized at Oklahoma State University Center for Veterinary Health Sciences (CVHS) since 1992. Over 400 animals have been treated using percutaneous laser disc abla...

Osteoma is one of the most common tumors of the cranial vault and the facial skeleton. For osteoma in the facial region, endoscopic resection is widely used to prevent surgical scarring. Tumors in a total of 14 patients were resected using an endoscopic holmium-doped yttrium aluminium garnet (Ho:YAG) laser with a long flexible fiber. Aside from having the advantage of not leaving a scar due to ...

A 25-year-old man presented with stones in left kidney received the left Percutaneous nephrolithotomy (PCNL) with holmium laser lithotripsy. All the stones were successfully removed, and all the results were normal in the first three months followup. However, a deterioration of renal function was confirmed two years later. No mechanical obstruction was found with ureteroscopy. The deterioration...

Symptomatic benign prostatic hyperplasia (BPH) is managed medically worldwide, but transurethral resection of prostate (TURP) is the gold standard in refractory cases. Holmium laser enucleation of prostate (HoLEP), laser vaporization are other options which are widely practiced. However in larger glands which are more than 80 g, open adenomectomy is still practiced. Laparoscopic adenomectomy is...
