ABSTRACT
Objective To evaluate the efficacy of the retroperitoneal laparoscopic pyelolithotomy (RLP) and the percutaneous nephrolithotomy (PCNL) in treating renal pelvic stone.Methods The data of 89 patients diagnosed as renal pelvic stone were retrospectively reviewed from January 2009 to July 2016,of whom 43 patients underwent RLP and 46 underwent PCNL.Statistical analysis was performed regarding operation time,blood loss,mean hospital stay,complication rate,and stone-free rate.Results The operation time in RLP group and PCNL group was (117.5 ± 16.7) min and (118.3 ± 16.6) min,respectively,and there was no significant difference (P =0.547).For the two groups,the mean hospital stay was (4.5 ± 0.5) d and (6.1 ± 0.9) d,the mean hemoglobin decrease was (4.5 ± 1.2) g/L and (18.1 ± 3.4) g/L,the post-operative blood transfusion rate was 2.3％ and 14.0％,the post-operative septic shock rate was 0 and 9.3％,respectively,with significant difference between the two groups (P ＜ 0.05).The stone-free rate in both groups was 97.7％ and 95.3％ with no significant difference (P =0.557).Conclusions RLP has the advantages of quick recovery,less blood loss and lower complication rate than PCNL.It could be a minimally invasive option for the treatment of renal pelvic stone.
ABSTRACT
Objective To summarize the safety and efficacy of Sunitinib in the treatment of metastatic renal clear cell carcinoma. Methods Fifteen patients with clear cell metastatic RCC were treated with Sunitinib,with 11 males and 4 females,aged from 26 to 74 years with median age of 55 years.Thirteen cases of 15 were T3 to T4 stage,and 8 cases underwent radical nephrectomy,while 5 other cases underwent renal biopsy with the pathological diagnosis of renal cancer.The other two cases (one man and one woman)with the solitary kidney renal cell carcinoma ( stage T1a) and renal insufficiency,were diagnosed as metastatic renal cell carcinoma by biopsy.Sunitinib monotherapy was administered by the regimen of 6 weeks per cycle with daily oral Sunitinib 4 weeks,followed by 2 weeks off ( from 1 - 10 cycles).Response was evaluated by RECIST.Renal tumor was 9.52 ± 3.3 cm in diameter at baseline,and the assessment of metastases included retroperitoneal lymph nodes (6 cases),mediastinal lymph nodes (3 cases),brain (2 cases),lung (6 cases),bone (2 cases) and liver (2 cases).Karnofsky score,tumor changes,adverse events and the survival of each patient was assessed and recorded. Results The follow-up duration was from 1.5 - 15months,with median follow-up of 6 months,and tumor response was evaluated by RECIST.Seven of 15 patients (46.7％) treated with Sunitinib achieved partial responses (PR),7 patients (46.7％) demonstrated stable disease (SD),and 1 patient (6.7％) developed progressive disease (PD) during the follow-up.Objective Response Rate (ORR) was 46.7％,PR + SD was 93.3％,6 months PFS was 93.3％,and median PFS was 12 months,respectively.Renal tumor was 8.7 ± 4.0 cm in diameter after therapy.Two PR patients with the obvious effectiveness had experienced progressed hypertension,and one cases with hypertension that could be controlled below 140/90 mm Hg ( 1 mm Hg =0.133 kPa) by a single drug before treatment,showed increased blood pressure ( ＞ 160/105 mm Hg) following the second cycles treatment,who were administered increased dosage and combination therapy.The other case without history of hypertension,showed high blood pressure ( ＞ 150/100 mm Hg) in the third cycle,and could be controlled well by antihypertensive drugs.Fortunately,the tumor of these two cases reduced obviously by more than 50％. 1/2 adverse reactions of 12 cases:yellowing of the skin and yellow sweat ( 12 cases,80％ ),fatigue ( 12 cases,80％ ),4 cases of hypothyroidism (26.7％),bilirubin and triglyceride levels elevated in 7case (46.7％); Four cases showed 3/4 degree adverse events with the emergence of gastrointestinal bleeding in one case secondary to platelets reduction (6.7％).Three cases (20％) showed serious fatigue,nausea,vomiting and severe hand-foot skin reaction. Conclusions Sunitinib is recommended for the treatment of metastatic renal clear cell carcinoma with good efficacy and safety.
ABSTRACT
OBJECTIVE:To study the quantity-effect relationship of reptilase with surgical hemostasis used at different dosages perioperatively and postoperatively.METHODS:120patients undergoing urological and general operations were ran-domly divided into experimental and control group.In the experimental group reptilase was administered at the dose of2KU by iv during the operation and continuously given at the dose of1KU～2KU by iv drip or iv twice a day after the operation until bleeding stopped.In the control group reptilase was administered at the dose of1KU by iv during the operation and continu-ously given at the dose of1KU by iv drip or iv once a day after the operation until bleeding stopped.RESULTS:The bleeding volumes in experimental and control group were(141?11.2)ml and(198?12.1)ml(P
