PURPOSE: To report a case of intracranial subdural hematoma occurring after a spinal dural tear that was made unintentionally during the course of a posterior laminectomy and spinal fusion at the L(5)-S(1) level. The possible physiopathological mechanisms are discussed. CLINICAL FEATURES: On the fourth postoperative day, a 59-yr-old woman displayed persistent headache following unintended durotomy during spine implant revision. Perioperative blood loss was 2840 mL and intravascular replacement was about 3000 mL. She was hydrated with iv fluids and treated with non-steroidal anti-inflammatory drugs. The symptoms improved but persisted. With the aggravation of the headache complicated with unconsciousness and the appearance of focal neurological signs on the eighth day, a computed tomography was obtained and revealed a right subdural hematoma. Following surgical drainage, the patient made an uneventful recovery. CONCLUSION: This case reminds us that subdural hematoma formation can complicate durotomy during spine surgery. Neurological deterioration in the postoperative period should prompt clinicians to rule out the diagnosis and intervene rapidly as appropriate.
PURPOSE: The natural history of prenatally diagnosed bilateral ureteropelvic junction hydronephrosis is unknown. No definite recommendations exist regarding management, and many authors recommend unilateral or bilateral pyeloplasty. We present the results of nonoperative management of bilateral hydronephrosis. MATERIALS AND METHODS: A total of 16 patients (32 kidneys) with prenatally diagnosed moderate to severe bilateral hydronephrosis were followed nonoperatively. Pyeloplasty was performed only for evidence of deterioration of function and only unilateral surgery was performed when necessary. RESULTS: Of the 32 kidneys 31 had moderate or severe hydronephrosis and 4 (12.5%) required pyeloplasty during a mean followup of 36 months. Hydronephrosis spontaneously resolved or improved in 78% of those observed nonoperatively. Of the 25 kidneys followed nonoperatively for at least 2 years 80% demonstrated improvement. While initial drainage half-time was more than 20 minutes in 55% of kidneys, 78% of unoperated kidneys had a final half-time of less than 20 minutes. Of the 10 kidneys with bilateral severe hydronephrosis 3 (30%) required pyeloplasty. All children had normal glomerular filtration rate for age at the latest followup. Only 1 child has persistent bilateral severe hydronephrosis at age 1 year. CONCLUSIONS: Initial nonoperative observation appears to be safe in all cases of moderate to severe bilateral neonatal hydronephrosis. Spontaneous improvement can be expected in most kidneys by 2 years. Only a few children require unilateral pyeloplasty and bilateral operation can be avoided in most cases.
OBJECTIVES: To evaluate the efficacy of a 7F tail stent with an 18F Councill nephrostomy tube and compare it to a 24F re-entry Malecot nephrostomy tube after percutaneous nephrolithotomy. METHODS: Forty patients were prospectively randomized to receive either a 24F re-entry Malecot nephrostomy tube (group A, n = 20) or a 7F tail stent with an 18F Councill nephrostomy tube (group B, n = 20) for postoperative drainage. Patients were evaluated with an analogue scale questionnaire 15 days after percutaneous nephrolithotomy at the routine office follow-up visit asking them to rate the flank pain on a 0 to 10 scale, urinary urgency on a 0 to 10 scale, and quality of life, while the external drainage tubes were still in place. RESULTS: The mean length of stay was 4.5 and 3.5 days for groups A and B, respectively. Flank urine leakage was present in all patients in group A for a period of 6 to 12 hours, and no patient in group B had any significant flank drainage. A statistically significant reduction of flank pain in favor of group B was observed (P = 0.0002). We did not observe any statistically significant difference when evaluating the urgency (P = 0.1) and quality-of-life scores (P = 0.09) between the two groups, even though a trend was noted toward amelioration in favor of group B patients. CONCLUSIONS: The results of the present study suggest that the 7F tail stent is certainly better tolerated by the patients after percutaneous nephrolithotomy compared with the standard 24F re-entry Malecot nephrostomy tube.
