Gum chewing stimulates bowel motility in patients undergoing radical cystectomy with urinary diversion.
Several studies have shown that gum chewing may stimulate bowel motility after gastrointestinal surgery. Because urinary diversion typically uses a segment of bowel, it is conceivable that patients undergoing cystectomy and diversion may benefit from gum chewing. This study aimed to determine whether gum chewing in the immediate postoperative period facilitates a return to bowel function in patients undergoing cystectomy and urinary diversion. ⋯ Gum chewing may speed the recovery of bowel function after cystectomy and diversion. These findings are consistent with outcomes in the colorectal surgery published data that support the use of chewing gum as an easy and inexpensive way to enhance recovery after surgery.

To determine the patient and noncontrast computed tomography (NCCT) stone characteristics that predict either of 2 extracorporeal shock wave lithotripsy (ESWL) outcomes: stone-free (SF) status or ESWL success. ⋯ Stone location is the most important factor in achieving SF status after ESWL. NCCT stone characteristics such as stone size, mean HU, and intrarenal location are important predictors of ESWL success.

To evaluate the effect of taurine, a potent antioxidant, on testicular ischemia-reperfusion injury due to excess reactive oxygen species produced by neutrophils after testicular torsion-detorsion. ⋯ The results of our study have shown that the administration of taurine exerts a beneficial effect on testicular ischemia-reperfusion injury. This effect might be partly the result of a reduction in reactive oxygen species generation by diminishing neutrophil recruitment to the testis.

With the advent of prostate-specific antigen (PSA) screening, the number of lymph node metastases found after radical prostatectomy (RP) has been decreasing. Although it has been shown in this population that immediate adjuvant androgen deprivation therapy (ADT) improves survival compared with initiating ADT at clinical recurrence, the effect of starting ADT at biochemical recurrence is unknown. We examined a series of patients with Stage D1 (T2-T4N1-N2M0) prostate cancer discovered after RP, most of whom started ADT at biochemical recurrence. ⋯ The results of our study have shown that survival for patients with Stage D1 prostate cancer after RP is excellent and equivalent to that of age-matched controls. Long-term pelvic morbidity due to primary tumor progression was prevented by RP. By waiting until PSA failure to initiate ADT, we found that a small percentage of patients (15% at 5 years) were rendered disease free with surgery alone and could avoid the side effects of ADT, with excellent overall survival maintained for those starting ADT at biochemical progression.

To assess the rate and predictive factors of urinary retention after iodine 125 brachytherapy for localized prostate cancer. ⋯ Catheterization for acute urinary retention after brachytherapy is an uncommon event. Our data suggest that preimplant US-based prostate volume and IPSS are the strongest predictors for catheterization. Catheterized patients who are refractory to medical therapy can safely undergo a minimal TUR-P.
