One hundred patients, 35 with spinal cord injury (SCI) and 65 who were ambulatory, underwent percutaneous nephrolithotomy (PNL). Success of complete stone excision, operative morbidity and mortality were compared in the two patient populations. Stone size and complexity were evaluated by X-ray and a single-stage PNL was done using general anesthesia, bi-planar C-arm fluoroscopy, Amplatz renofascial dilators, and two guide wires. Eleven percent of the patients had previously-placed percutaneous nephrostomy tubes for hydronephrosis and/or pyonephrosis. In the ambulatory group, 98.5% (64/65) were stone-free after the procedure as compared to 85.7% (31/35) in the SCI group. The success rate in those patients who followed postoperative instructions exceeded 96% in both groups of patients. One operative mortality, related to infectious complications, occurred in the SCI group. Major morbidity in the SCI population consisted of three perirenal abscesses, a hydrothorax, an aspiration pneumonia, a respiratory arrest and a nephro-colonic fistula for a rate of 20% (7/35), or 7% of all patients. One major complication, a nephroduodenal fistula, occurred in the ambulatory population. Four patients, three of whom were SCI, required open surgery related to infectious complications. Other significant complications consisted of hemorrhage requiring transfusion, and fever (101.5 degrees F). Minor complications included dislodged nephrostomy tubes, retained stones, and ureteral edema causing obstruction. These complications were three times more common in the SCI population. Percutaneous nephrolithotomy is an effective surgical means for stone removal for SCI and ambulatory patients. The SCI patient has a high incidence of infectious complications causing increased morbidity and mortality.

Introduction of nasogastric feeding tubes is usually blindly performed and is generally considered a safe procedure. However, the rate of complications of a blind insertion technique varies from 0.3 to 15%, and is usually related to inadvertent insertion of nasogastric tubes into the trachea and distal airways. The main predisposing factors related to tube malpositioning and complications are altered mental status with decreased cough or gag reflex, a preexisting endotracheal tube and severe illness. Complications include severe aspiration pneumonia, hydrothorax, hemothorax, empyema and pneumothorax. The mortality related to misplacement of a nasogastric tube is around 0.1-0.3% of the procedures. This 61-year old female had a history of poor appetite, weight loss, dyspnea and fever. A chest axial computerized tomography showed enlarged mediastinal lymph nodes. Laboratory showed hypercalcemia with normal PTH and hypokalemia. As the patient remained anorectic, a nasogastric feeding tube was placed, through which the administration of enteral diet, by continuous infusion pump, was started. After 12 -en.jpg-en.jpghours the patient developed dyspnea, hypoxemia and hypotension. During orotracheal intubation, it was disclosed the presence of the nasogastric tube in the trachea as well as the infused diet within the respiratory tract. Autopsy revealed an unusual complication of a nasogastric tube misplacement, which led to a massive collection of enteral nutrition fluid into the pleural space - a "nutrothorax". Additionally, an underlying stage IV anaplastic large cell lymphoma with interstitial lung and bronchial mucosa involvement was diagnosed.
