RESUMO
【Objective】 To investigate the predictive value of preoperative platelet/lymphocyte ratio (PLR) and neutrophil/lymphocyte ratio (NLR) (NLR-PLR) in peripheral blood for the prognosis of patients with upper urinary tract urothelial carcinoma (UTUC) undergoing radical surgery. 【Methods】 The clinical data of 104 UTUC patients who underwent radical nephroureterectomy plus bladder sleeve resection in our hospital during Jan.2015 and Dec.2020 were retrospectively analyzed. The receiver operating characteristic (ROC) curve was drawn according to NLR and PLR, the optimal cut-off values of NLR and PLR were calculated, and NLR-PLR was determined accordingly. The patients were divided into NLR-PLR group 1 (PLR ≥161.46 and NLR≥ 2.51) and NLR-PLR group 0 (remaining patients). Chi-square test was used for comparison between groups, and the Kaplan-Meier method was used to draw survival curves. According to the Cox univariate and multivariate risk regression models, the risk factors for decreased overall survival (OS) were determined. 【Results】 The optimal cut-off values of PLR and NLR were 161.46 and 2.51, respectively. There were 74 patients in the NLR-PLR group 0 and 30 in the NLR-PLR group 1. Cox multivariate regression analysis showed that T stage, maximum tumor diameter and NLR-PLR were independent risk factors for reduced OS (P<0.05). 【Conclusion】 Preoperative NLR-PLR is a potential predictor of the prognosis of UTUC patients. Higher NLR-PLR is associated with poorer prognosis.
RESUMO
Objective To evaluate the risk factors of septic shock after mini-percutaneous nephrolithotripsy (mPCNL). Methods Clinical data of 1 590 cases who underwent mPCNL from January 2013 to December 2014 were retrospectively analyzed. The x2 test and logistic regression were used to identify the key risk factors for septic shock after mPCNL. Results Of the 1 590 patients, 18 patients suffered septic shock, including 6 male patients and 12 fe﹣male patients. Their mean age was (45.6 ± 13.5) years (28 ~ 69 years). White cell in urine was 100 percent, the stone diameter ranged from 1.5 to 5.0 cm, unichannel for 15 cases while multichannel for 3 cases, the operation du﹣ration ranged from 45 to 200 min, mean (87.0 ± 56.0) min. 2 in 18 cases died in multiple organ failure, the others recovered till discharged. In x2 test, female gender (P = 0.001), (+++ ~ ++++) white cells in urine (P= 0.042), un-preoperative nephrostomy drainage (P=0.041) had significant association with septic shock after mPCNL. While in multivariate analysis, female gender ( O? = 5.471, 95 % CI: 0.756~21.452, P< 0.05) and un-preoperative nephrostomy drainage (O? =3.106, 95%CI:1.283~7.907, P<0.05) were identified as independent risk factors for septic shock after mPCNL. Conclusions Female gender and un-preoperative nephrostomy drainage are the key risk factors for septic shock after mPCNL.
RESUMO
Objective To raise the awareness of the glandularis ureteritis. Methods Five cases with glandularis ureteritis confirmed by pathological examination from Jan 2001 to Jun 2012 were reviewed. The diagnosis was assessed on histopathologic studies in all. The clinical manifestations, the diagnosis and treatment were discussed. Results Resections of the affected ureter and ureteroplasty were undertaken for 2 patients. Ureteronephrectomy was performed for 2 patients because of serious hydronephrosis due to obstruction. Electrofulguration via-ureteroscopy was carried out for another patient. All patients have been well and without recurrence on following up for 15 to 152 months, with an average of 86.6 months. Conclusion Glandularis ureteritis is not frequently seen and the etiopathogenesis is not yet clear. Biopsy is very important for suspected neoplasm of ureter before performing nephrectomy.
RESUMO
Objective To discuss the long term clinical effect of ileal orthotropic neobladder.Methods From 1991 to 1998,79 patients,mean age 55(41～75)years,male 74,female 6,were followed up.The serum creatinine and urea,electrolytes,blood routine,B ultrasonic scan of the neobladder residual urine and IVU or MRU of the patients were followed up.The max transverse diameter of renal pelvis and the max verticaI/level diameter of neobladder were measured in 5,10 to 14,15 years of postoperative when IVU or MRU.All results of different time were compared by the multiple comparisons.The local or distant cancer recurrence and the complications of the operation Were evaluated. Results Sixty-four cases,58 male,6 famle,were long term followed up:mean time was 167 (range,121～216)months.Seven cases died of other diseases.Seven cases had pelvic recarrence.Two cases had urethral recurrence.Three cases died of tumor metastasis.One case had ureter recurrence.Forty-eight patients were alive more than 10 years.The value of the serum creatinine,urea,electrolytes and bloods routine of the patients were normal after 5,10 to 14 and 15 vears postoperative (P＞0.05).The max transverse diameter of the renal pelvis in 5,10 to 14 and 15 years Dostoperative were 14.0 mm,14.1 mm and 13.7 mm,respectively,P＞0.05.The max vertical/level diameter of the neobladder in 5,10 to 14,15 years of postoperative were 110.4 mm/90.4 mm,111.5 mm/95.3mm and 127.0 mm/97.0 mm,respectively,P＞0.05.The residual urine of 5 cases was more than 50 ml and had not increased during follow up.Eight cases with neobladder stone were cured by the intracavitary lithothrypsis.Two cases with uretheral stricture were cured by the intracavitary therapy.Twelve cases of 14 cases with inguinal hernia were cured by reoperation,2 cases accepted conservative treatment.Only 17 cases had no complication involve of the cancer and the operation. Conclusion The upper urinary tract and neobladder of the ileal orthotopic neobladder could be stable for long time,the cure rate of tumor is satisfactory and the lifetime follow up is necessary.
RESUMO
Objective To study the application of transurethral bipolar plasma kinetic vaporization of the distal ureterectomy in radical nephroureterectomy for renal pelvic or ureteral carcinoma. Methods A total of 6 patients with renal pelvic or ureteral carcinoma without involvement in ipsilateral distal ureter,ureteral orfice,and the bladder were included.Radical nephroureterectomy was performed by using transurethral bipolar plasma kinetic vaporization combined with either flank incision nephrectomy (5 patients) or retroperitoneal approach laparoscopic nephrectomy(1 patient). Results The operation was completed smoothly in the 6 patients with comparatively little blood loss.The operation time was 120~210 min(mean,150 min).Obturator nerve reflex happened in no patients during the operation.Postoperative bladder irrigation found no bleeding in the bladder.The time of indwelling the catheter was 7~9 d(mean,8 d).Hypogastralgia and fever occurred in 1 patient on the 5th postoperative day.And the patient was confirmed as having mild urinary extravasation and was given catheter indwelling for 5 days. Transuretheral cystography found no leakage and a full recovery of voiding function was achieved.Postoperative pathological findings showed negative margins in all the patients.One patient died of myocardial infarction 3 months after operation,while follow-up in the remaining 5 patients for 7~21 months(mean,16 months) showed no tumor recurrence. Conclusions Application of transurethral bipolar plasma kinetic vaporization of the distal ureterectomy is micro-invasive,with little hemorrhage and few complications.It is an effective assistant option in radical nephroureterectomy.
