In some cases of primary transitional cell carcinoma (TCC), there may be some uncertainty in clinical decision making. We present a case in which a pT1-N0 urothelial tumor was found in the renal pelvis after an open nephrectomy for urolithiasis. Because incomplete excision of the ureter can lead to recurrence of the TCC, we deemed it necessary to remove the residual ureter. Therefore, a combined endoscopic-transvescical laparoscopic ureterectomy was performed. The transabdominal approach was chosen for the procedure, because the patient had already undergone open nephrectomy with retroperitoneal access and was thus likely to have adhesions and inflammation in the region. For the endoscopic phase of surgery, a technique of ureteral intussusception was combined with transurethral resection. The choice of the endoscopic transurethral procedure was prompted by the fact that transurethral resection of the ureteral orifice and invagination ureterectomy has already been proposed as the first step of nephroureterectomy. The combined endoscopic laparoscopic procedure was not technically demanding; the ureterectomy took no longer than an open procedure. The surgery was uneventful, and the patient resumed normal activities the day after surgery. The broader issue of whether this technique should be adopted by the urological community at large as a routine practice requires longer follow-up outcome data.

In a large population of animals, it is normal to have some die each day from causes not related to disease, which is often referred to as natural causes. In poultry production, this phenomenon is commonly referred to as daily mortality. In egg-producing chickens, many of the natural causes of death are associated with making an egg. The causes of normal mortality in commercial egg-laying chicken flocks have been described very little to date. A commercial chicken egg farm, housing approximately two million single-comb white leghorn chickens (Gallus gallus domesticus) in 16 egg-producing flocks, was visited on a monthly basis to monitor bird health, body conditioning, skeletal integrity, and causes of daily mortality in an attempt to provide early detection of health abnormalities. A representative sample of daily mortality from each flock was necropsied to determine the cause of death. Reported herein is a summary of visits for a period of 38 mo from June 2011 to July 2014. The top 15 causes of normal mortality, in rank order of prevalence, were determined to be the following: egg yolk peritonitis, hypocalcemia, gout, self-induced molt, salpingitis, caught by spur, intussusception or volvulus (twisted intestine), cannibalism (pick out), tracheal plug, septicemia, fatty liver syndrome, internal layer, layer hepatitis, persecution, and prolapsed vent. Other causes noted were hyperthermia (during summer), trauma, coccidiosis, ovarian neoplasia, being egg bound, urolithiasis, peritonitis (not egg yolk induced), leg fracture, caught in the structure, tumor (other than ovarian origin), wing fracture, exsanguination, and cardiomyopathy.
