Randomized Controlled Trial Comparative Study
Comparison of effects of dexmedetomidine-ketamine and dexmedetomidine-midazolam combinations in transurethral procedures.
To compare the effects of dexmedetomidine-ketamine and dexmedetomidine-midazolam combinations on the recovery time, hemodynamic and respiratory variables, and side effects in patients undergoing transurethral procedures. ⋯ Both combinations provided satisfactory sedation levels, but the dexmedetomidine-ketamine combination provided better analgesia and hemodynamic stability, with less nausea and vomiting and shorter recovery time, than the dexmedetomidine-midazolam combination.

Urinary stones are rarely seen in the urethra and are usually encountered in men with urethral stricture or infection. We describe a unique case of giant impacted stones in a 20-year-old man with unreal penile erection.

To examine the rates of long-term biochemical recurrence-free survival (BRFS) with respect to isotope in intermediate-risk prostate cancer treated with external beam radiotherapy (EBRT) and brachytherapy. ⋯ (125)I renders a superior rate of BRFS compared with (103)Pd when used with EBRT. Hormonal therapy does not provide additional benefit in patients with intermediate-risk prostate cancer treated with a combination of EBRT and brachytherapy, except for the addition of hormonal therapy to (103)Pd.

To investigate the potential protective effects of selenium and lycopene, either alone or in combination, for cisplatin-induced oxidative stress and testicular dysfunction in male rats. ⋯ Selenium and lycopene supplementation reduced cisplatin-induced testicular toxicity, improved testicular function and prevented cisplatin-related injury to the rat testes by suppression of oxidative stress.

To establish some guidelines for the definition, diagnosis, and treatment of failed posterior urethroplasty. ⋯ Unsuccessful outcomes can be encountered shortly after removal of the urethral stent or delayed for several months or years after surgery. Early cases present by an inability to void or incontinence and usually require salvage urethroplasty or bladder neck repair. Late cases present by a weak urinary stream, are due to narrowing of the anastomosis, and are usually corrected by direct visual internal urethrotomy.
