Objective To investigate the clinical outcomes of minimally invasive percutaneous nephrolithotomy(MPCNL)in the treatment of lower caliceal calculi.Methods We retrospectively re- viewed the clinical outcomes and complications of 33 patients who underwent MPCNL for lower caliceal cal- culi from March 2001 to April 2005.The average diameter of the calculi was 2.8 cm.Single tract nephrosto- my was performed in all 33 cases;among them renal access was obtained through a middle calyx in 10 cases and a lower calyx in 23.Nine cases had F14 renal access;and 24 cases,F16.Results Of 33 cases,28 (85%)achieved stone-free at 1 session.A second-look was needed in 3 cases due to intraoperative bleed- ing;ESWL,in 1 case with residual,calculi;no treatment,in 1 case with residual calculi＜4 ram.The mean operative time was 93 min;mean blood loss was 113 ml;mean hospital stay was 11 d.Blood transfusion was needed in 1 patient who suffered from hepatic cirrhosis preoperatively;another experienced severe bleeding 7 d after operation and was cured with hyperselective spongia gelatinosa embolization of the renal artery.Fol- low-up was available in 19 cases for 2-48 months,and no recurrence of renal calculi was noted.Conclu- sions Minimally invasive percutaneous nepbrolithotomy has advantages of safety,less invasion,and easy re- covery for the treatment of lower caliceal calculi.

Objective To report our experience with minimally invasive percutaneous nephrolithotomy (MPCNL) in treatment of renal calculi in solitary kidneys. Methods From August 2000 to August 2010, 242 patients with renal calculi in solitary kidneys were treated by MPCNL, the data were reviewed retrospectively. Results The mean operative time was 68 min, the clearance rates were 79.3% (192/242) after first session and 88. 0% (213/242) after second-look MPCNL and ESWL, respectively. Postoperative fever happened in 18 cases. Twenty-one cases required transfusion, 10 cases received angiography and embolization. One case experienced perirenal hematoma and 1 case had pneumatothorax. Conclusions MPCNL has the advantages of less bleeding, high clearance rate and short hospital stay. MPCNL is an effective and feasible treatment option for renal calculi in solitary kidneys and should be the first line choice.

Abstract: Objective　To investigate the clinical characteristics and diagnosis key points of brain abscess caused by Nocardia asiatica, and provide a clinical basis for diagnosing and treating intracranial infection caused by Nocardia. Methods　A case of pulmonary Nocardia asiatica complicated with brain abscess diagnosed at the Second Affiliated Hospital of Hainan Medical University was selected to analyze the clinical manifestations, cerebrospinal fluid characteristics, pulmonary and cranial imaging features, and treatment plan, and to summarize the diagnosis and treatment experience. Results　The patient was an elderly woman with a history of diabetes, dry cough was the first symptom without fever or headache. At the beginning of the course, it was diagnosed as pulmonary infection and tuberculosis in the local hospital, and received conventional antimicrobial and anti-tuberculosis therapies, but showed no improvement. The patient developed progressive limb weakness, followed by consciousness disorders, and coma. Cerebrospinal fluid (CSF) adenosine deaminase and lactate dehydrogenase were not abnormal, CSF pressure, protein and white blood cells were high, mainly with multiple nuclear cells. CSF glucose and chloride were normal in the early stage of the disease, but decreased significantly in the later stage. Metagenomic analysis of cerebrospinal fluid indicated Nocardia asiatica with a specific sequence number of 537. Lung CT showed exudation, abscess, and cavity in the right lung. Skull MRI scan + enhancement suggested multiple scattered abscesses in both cerebral hemispheres. The abscesses were of different sizes and showed ring enhancement, with extensive surrounding edema, and ventricular compression. After treatment with meropenem, linezolid, and compound sulfamethoxazole tablets, the cerebrospinal fluid recovered, and the lesions in the lungs and intracranial structures improved. Conclusions　Brain abscess caused by Nocardia asiatica is similar to the tuberculous brain in clinical symptoms, cerebrospinal fluid examination, craniocerebral imaging, so we should be alert to the possibility of Nocardia infection in patients with diabetes. At the same time, metagenomic testing of the cerebrospinal fluid can help confirm the diagnosis. The mortality and disability rates of brain abscess caused by Nocardia are high. Early diagnosis and treatment can improve the prognosis.
