ABSTRACT
【Objective】 To investigate the application of different ureteral length measurement methods in the indwelling of double-J stent. 【Methods】 Clinical data of 260 patients with double-J stent indwelling after ureteroscopic surgery during Jul.2018 and Dec.2020 were prospectively analyzed. The patients were randomly divided into height calculation group, CT measurement group, KUB group and ureteroscopic measurement group. The length of ureter was calculated accordingly and the appropriate length of double-J stent was selected. KUB was performed on the first day after operation and before extubation to determine the position of double-J stent. The patients completed the ureteral stent-related symptom questionnaire (USSQ), urinary symptom score, lower urinary tract symptom (LUTS) score, pain score, hematuria score, and quality of life score before and after double-J catheter placement. 【Results】 There were no significant differences in age, gender, height, side of stent and urinary symptom score among the four groups (P>0.05). The average lengths of the ureters measured by the four methods were (21.5±1.0) cm, (21.5±1.8) cm, (23.8±1.3) cm and (21.7±1.8) cm, respectively. There were no significant differences among the height calculation group, CT measurement group and ureteroscope group, but there was significant difference between the three groups and the KUB group. The ideal ureteral stent length indwelling ratio in the ureteroscopic group was 76.9%, which was better than that in the other three groups. Postoperative indwelling time was 7-42 d (mean 29.8 d). The USSQ score of the ureteroscopic group before extubation was (14.1±1.5), which was lower than that of the other three groups (P<0.05). The ureteroscopic group was better than the other three groups in the comparison of frequency and urgency of urination, nocturia, hematuria, quality of life score, and pain score (P<0.05). 【Conclusion】 Intraoperative ureteroscopic measurement of the ureteral length is a simple and feasible method in guiding the indwelling of double-J stent to reduce ureteral stent related symptoms.
ABSTRACT
Objective To systematically evaluate the necessity of presetting double-J stent before flexible ureteroscope lithotripsy.Methods Computer retrieved clinical studies on the effect of preoperative presetting double-J-catheter on flexible ureteroscope lithotripsy in PubMed,Cochrane Library,Embase,Scopus,Wan fang,CNKI and VIP databases were reviewed.The retrieval time was from the database construction to November 2018.All of the possible combinations of the following terms were used for the search:flexible ureteroscopic,preoperative,double J stent,and calculus.Two researchers independently conducted literature screening,quality evaluation and data extraction,and completed Meta analysis by using statistical software RevMan5.3.Results Thirty-two case-control trials and 14 randomized controlled trials were screened,with a total of 17 480 patients,including 6 211 patients in the experimental group and 11 269 patients in the control group.The results of meta-analysis showed that the experimental group was superior to the control group in term of the overall postoperative stone clearance rate (OR =1.69,95％ CI 1.37-2.08,P ＜0.05).In terms of postoperative kidney stone removal rate,the experimental group was superior to the control group (OR =1.67,95％ CI 1.41-1.99,P ＜ 0.05).In terms of the removal rate of ureteral calculi after surgery,there was no significant difference between the two groups (OR =1.71,95％ CI 0.91-3.20,P =0.10).The success rate of flexible ureteroscope access sheath implantation was higher in the experimental group (OR =5.77,95％ CI 3.32-10.31,P ＜0.05).The rate of passive usage balloon dilation in the control group was higher (OR =0.23,95％ CI 0.15-0.35,P ＜ 0.05).For the incidence of intraoperative complications,the experimental group was lower (OR =0.56,95％ CI 0.38-0.84,P =0.004).For the incidence of postoperative complications,the experimental group was also lower (OR =0.64,95％ CI 0.45-0.90,P =0.01).The operation time of the control group was longer (MD =-4.95,95 ％ CI -8.90--1.01,P =0.01).Conclusions Presetting double-J-catheter can improve the stone removal rate after flexible ureteroscope lithotripsy for the treatment of kidney stone,improve the success rate of flexible ureteroscope access sheath implantation,reduce the utilization rate of ureteral balloon dilator,reduce the incidence of intraoperative and postoperative complications,and shorten the operation time.
ABSTRACT
Background: In few studies, Dexmedetomidine was used an adjuvant to local anesthetics in peripheral nerve blocks Aim: This study was aimed to examine the effect of adding Dexmedetomidine to Bupivacaine 05% during the femoral sciatic nerve blocks and to evaluate its effect in prolonging post-operative analgesia Materials and methods: This was a prospective, double blinded, randomized study which consisted of 80 patients, Patients were randomly allocated into two groups (40patients each): In group BD, (Bupivacaine-Dexmedetomidine hydrochloride), one mL, containing 100 μg, was added to 39 mL of Bupivacaine 05% In group B; 1 mL of normal saline was added to the same volume of Bupivacaine 05% Results: There were no statistically differences between the two groups in demographic data and surgical characteristics The onset time of sensory block, motor block and surgical anesthesia time were significantly shorter in group BD when compared to group B The durations of sensory block, motor block and analgesia were longer in BD group when compared to group B Systolic arterial pressure (SAP) and heart rate were significantly lower in group BD when compared to group B from 10 to 90minutes after initiation of block (P<005), diastolic arterial pressure was similarly lower in group BD at 45, 60, and 90 minutes following initiation of block Conclusion: This study showed that a prolonged duration of analgesia was associated with addition of Dexmedetomidine 100μg to bupivacaine 05% during US-guided combined femoral and sciatic block for below knee surgery and is also associated with significant bradycardia requiring treatment
ABSTRACT
Double J stents have good effects on support and the internal drainage, they can drainage urine,and can play an important role in drainage urine, improving renal function and preventing ureteral stricture. The retention of two double J tubes in the lumen of the ipsilateral urinary tract is better than the retention of single double J tube in some cases.
ABSTRACT
Double J stents are an integral part of urological practice today. Ureteral stenting is done as an adjunct to ureteral surgery and for managing ureteral obstruction. Every urological surgery doesn't require DJ stenting and their use must be strictly restricted to selected cases. Retension is a common complication of ureteral stents and is mostly due to encrustations on a forgotten DJ stent. Here we report a case of retained DJ stent which was placed during open nephrolithotomy. It was neither forgotten nor encrusted, but was embedded in the renal parenchyma. As per our knowledge this is the first case of its kind to be reported in medical literature.
ABSTRACT
Objective To investigate the method of the resectoscope combined with ureteroscope in seeking for the difficult ureteral orifice in glandular cystitis, which improved the success rate of double J stent insertion under endoscopy.Methods The clinical data of 8 patients with dififcult ureteral oriifce in glandular cystitis from March 2015 to May 2016 were retrospectively analyzed. All male patients, their age ranged from 38 to 64 years old, the average age was 44.3 years. The depth of the submucosa and muscle layer of the bladder lesion was treated by transurethral resection. The necrotic tissue of ureteral oriifce was excised, which revealed the changing of muscular layer of texture. Then, resected the muscle tissue, urine was seen through the thin layer of muscle tissue. Under the guidance of the guide wire was inserted, the ureteroscope observation was confirmed ureteral lumen and the double J stent was placed.Results All patients were successfully placed double J stent. The mean operation time was 83.2 min (range, 35.0~205.0 min). Intraoperative blood loss was range 20~50 ml. The catheter was removed in 3~5 d. The abdominal plain iflm was reviewed in 1 - 2 days and the position of the double J stent was good, there was no ectopic, distortion and so on. There was no complications occurred during the perioperative period.Conclusions Resectoscope combine with ureteroscope in seeking for the dififcult ureteral oriifce in glandular cystitis is an effective way of increasing the successful rate of ifnding dififcult ureteral oriifce. This method is safe,minimally invasive and avoiding open surgery.
ABSTRACT
Objective To present our experience with the management of symptomatic ureteral calculi during pregnancy and to compare the effi?cacy of two treatments:double?J stent insertion and ureteroscopy. Methods In a retrospective study between January 2007 and January 2015,38 pregnant women were treated for symptomatic ureteral calculi in our hospital. The patients were divided into two groups based on whether they re?ceived double?J stent insertion(n=21)or ureteroscopic lithotripsy(n=17). We collected and compared the patients 'characteristics and treat?ment outcomes,such as success ratio,rate of complications,surgical time,medical costs,and hospitalization time. Results In the double?J group, the insertion of a double?J stent was possible for 17 of 21 patients(success rate,81.0%). In the ureteroscopy group,15 of 17 patients had complete calculi fragmentation(success rate,88.2%). Complications in the double?J stent retention group were slightly higher than in the ureteroscopic litho?tripsy group. The medical costs and hospitalization time required to perform ureteroscopic lithotripsy were significantly higher compared to double?J stent insertion. Patients in the double?J group contended with stones after delivery. Conclusion Both of double?J stent insertion and ureteroscopic lithotripsy are effective for the treatment of symptomatic ureteral calculi during pregnancy. The success rate of ureteroscopy ,which can directly dis?rupt stones,was higher. However,double?J stent insertion costs less and is simple and convenient. The technique that is chosen to be performed de?pends on the patient's practical situation and personal preference.
ABSTRACT
Objective To systematically evaluate the optimal indwelling time of double?J stent in the treatment of ureteral complicated calculi post?ureteroscopy. Methods A total of 161 patients with complicated ureteral calculi were enrolled in this study from August 2012 to August 2015. All patients received the treatment of ureteroscopic holmium YAG Laser lithotripsy and were randomly divided into 3 groups according to varied double?J stent indwelling time: group A 6 weeks (n = 51). Complications of three groups were compared and the hydronephrosis after removing double?J stent was recorded. Results The rate of complications of group C was significantly higher than that in group A and group B (P<0.017). However,group A(10/43)has a higher rate of ureterostenosis after removing double?J stent compared with group B(4/67)and group C(3/51),while no statistical significance was observed between group B and group C. Conclusion The incidence of complications after lithotripsy increased with the indwelling time of double?J stent,but the short indwelling time would led to ureterostenosis. Therefore,the optimal indwelling time of double?J stent after flexible ureteroscopy was 2 to 6 weeks,and the indwelling time for patients with injury ureteral mucosa could be appropriately prolonged.
ABSTRACT
Objective To evaluate the efficacy of combination therapy with α and M receptors antagonist for the treatment of double J stents related lower urinary tract symptoms.Methods From January 2013 to December 2016,one hundred and twenty patients were accepted the doubte J stents indwelling after the ureteral lithotripsy,laparoseopie ureterlithotomy and pyeloureteroplasty.They were divided into four groups randomly,including control group(30 cases,no drugs were taken),tamsulosin group(30 cases,0.2 mg tamsulosin was taken qd),solifenacin group(30 cases,5 mg solifenacin was taken qd),combination group(30 cases,0.2 mg tamsulosin and 5 mg solifenacin were taken qd).The IPSS scores,QOL scores and visual analogue pain scale(VAPS)scores were assessed pre-operation,1 week after operation,and 4 weeks after operation, respectively.Results The total IPSS scores in the combination group 4 weeks after operation was(8.21±2.36) points,compared with the control group((13.68 ± 3.65)points),the tamsulosin group((12.59 ± 3.76) points),the solifenacin group((12.39 ±4.58)points),the difference was statistically significantly lower(F=7.905,P<0.05).And 4 weeks after operation,the QOL scores in the combination group((1.52±0.99)points) was significantly lower than that in the control group((2.86±1.14)points),the tamsulosin group((2.69± 1.21)points)and the solifenacin group((2.74 ± 1.40)points)(F=13.725,P<0.05).While the VAPS scores didn′t show significant differences among those groups(P>0.05).Conclusion α and M receptors antagonist combination therapy can significantly improve lower urinary tract symptom due to indwelling double J stents.
ABSTRACT
Objective To explore the optimum time of removal of preoperative double J stent before adjuvant radiotherapy in cervical cancer. Meth?ods A total of 90 patients with cervical cancer who underwent radical surgery between January 2014 and March 2015 were retrospectively analyzed. In addition,these recruited patients also underwent preoperative placement of double J stent and had them removed before the adjuvant radiotherapy. The patients were then divided into three groups based on the time of removal of double J stent. Group A(n=21)had the stent removed 2 to 4 weeks after the surgery;group B(n=46)had the stent removed 4 to 5 weeks after the surgery;group C(n=23)had the stent removed greater than or equal to 5 weeks after the surgery. The complications caused by stent placement and their improvement after stent removal were compared among the three groups. Finally,the optimum time of stent removal was determined. Results The overall incidence of complications caused by stent placement in group B(23.91%)was significantly lower(P0.05)among the three groups concerning glomerular filtration rate,serum urea nitrogen,and serum creatinine. Conclusion The incidence of complications caused by preoperative double J stent place?ment increased along with the duration of placement,but the exacerbation of hydronephrosis should be concerned if the stent is removed too early. Therefore,the optimal time of stent removal is 4 to 5 weeks after the surgery.

ABSTRACT
Objective To investigate the clinical outcomes derived from Ningmitai combined with tamsulosin to prevent double-J stent syndrome after laser lithotripsy with ureteroscope. Methods 117 patients underwent laser lithotripsy with ureteroscope and then placed a double-J stent for draining were collected from January 2010 to January 2013. Patients with double-J stent placement were divided into four groups determined by dosage regimen. Tamsulosin group (30 cases) was treated with tamsulosin (0.4 mg once daily) lonely, Ningmitai group (29 cases) was treated with Ningmitai (1.52 g, trice time a day) lonely, tamsulosin combined Ningmitai group (30 cases) was treated with tamsulosin and Ningmitai at the same time, operation control group (28 cases) was neither tamsulosin nor Ningmitai. The catheter was removed on the 3rd day post-lithotripsy and then remained double-J stent for 1 month. The scores of urinary tract, pain and the incidence of gross hematuria were assessed. Results The significant differences in the improvement of symptom score (χ2=22.038, P=0.000), pain score (χ2=9.876, P=0.020) and hematuria (χ2=8.000, P=0.046) were found among tamsulosin group, Ningmitai group, and tamsulosin combined Ningmitai group. The number of patients with symptomless, slight symptom in tamsulosin combined Ningmitai group were higher than those of tamsulosin group, Ningmitai group, operation control group (symptomeless:14 vs. 6, 3 and 2 cases;slight symptom:13 vs. 9, 5, 4 cases). The number of patients with>Ⅱpain score (7 vs. 9, 14, 17 cases) and incidence of hematuriag [26.6%(8/30) vs. 56.7%(17/30), 58.6% (17/29), 53.6% (15/28)] were lower in tamsulosin combined Ningmitai group than those of tamsulosin group, Ningmitai group, operation control group. The drug combination of Ningmitai with tamsulosin had the synergism to relived symptom and pain, and showed the more obviousthan lonely use. Conclusion The drug combination of Ningmitai with tamsulosin can be used in clinic for prophylactic purpose to prevent double-J syndrome.
ABSTRACT
Fungi classified under the genera Bipolaris are dematiaceous hyphomycetes which are rare sources of human diseases. The dematiaceous fungi in other words “black fungi” are so named due to the presence of dark melanin like pigment in their cell wall. Majority of the species of Bipolaris, are either soil saprobes or plant pathogens, however few species of these saprobes like Bipolaris australiensis, Bipolaris hawaiiensis & Bipolaris spicifera are potential pathogens which are capable of causing infections in both immunocompetent & immunocompromised humans. The spectrum of human infections caused by Bipolaris include cutaneous and subcutaneous infections, allergic sinusitis, keratitis, allergic broncho pulmonary diseases, orbitopathy, CNS infections, Peritonitis associated with Ambulatory peritoneal dialysis, infections of implant devices & allografts. Here we report a case of ureteric infection due to Bipolaris species in a patient with Double J (DJ) stent in situ. Amphotericin B, itraconazole, voriconazole and imidazole are common antifungals found to be effective in treating Bipolaris infections.
ABSTRACT
Objective To investigate the clinical value of shortening double-J stent indwelling time in the treatment of ureteral stone-street complications after flexible ureteroscope lithotripsy . Methods Clinical data of 38 cases of ureteral stone-street complications following flexible ureteroscope lithotripsy from January 2012 to December 2013 in our hospital were retrospectively analyzed.The patients were divided into Group A (extubating the double-J stent two weeks after the surgery ) and Group B (retaining the double-J stent) with 19 cases in each group .The stone clearance results were compared . Results All the urinary calculus in Group A had been removed successfully , including 2 cases of renal colic , 3 cases of irritative symptoms of bladder and 3 cases of gross hematuria.Hospital cost was (766.5 ±153.7) yuan.Urinary calculus were successfully removed in 13 cases in Group B, including 19 cases of gross hematuria and 17 cases of irritative symptoms of bladder.No renal colic occurred.The hospital cost was (1251.2 ± 155.6) yuan.Compared with Group B , Group A has higher success rate of stone clearance , lower hospital cost and lower rate of bladder irritative symptoms and gross hematuria (P0.05). Conclusions Removing the double-J stent 2 weeks after flexible ureteroscope lithotripsy resulted in higher stone clearance rate and less complications compared with retaining the double -J stent.It can reduce the occurrence of irritative symptoms bladder and gross hematuria .
ABSTRACT
Objective To evaluate clinical efficacy of extracorporeal shock wave lithotripsy (ESWL) for treating patients with double J (DJ) stent extubation difficulties.Methods A retrospective analysis were conducted from July 1999 to December 2013,total 30 cases (18 male and 12 female) were accepted the ESWL therapy for treating the DJ extubation difficult due to the stone scales surface.The average age in those patients was 46 years (range 24 to 83 years).The average duration of DJ stents indwelling was 8.3 months (range 1.5 to 36.0 months).There were 10 cases with single stone and 20 cases with multiple stones.The distribution of stone location included left kidney in 14 cases,right kidney in 6 cases,left ureter in 3 cases and right ureter in 7 cases.The ureteral stone scales around the DJ stent showed tubular distribution.The distribution of imaging characteristic included kidney stones around the DJ stent joint in 20 cases and surface coarse in 10 cases.The diameter of the stone ranged from 0.7 to 3.2 cm (mean 1.8 cm).All the 30 cases were treated by ESWL with the 2 000-3 300 times frequency (mean 2 800 times).Treatment voltage was 4-8 KV.Results Gravel time ranged from 40 to 70 min (mean 45 min).No intraoperative and postoperative complications occurred.Their DJ stents were easily extubated immediately after ESWL.One week after ESWL,all the patients reported the flushing of the stone.Conclusion ESWL is a simple,convenient and efficacy way to solve the DJ stent extubation difficulties due to the scales surface.
ABSTRACT
Objective To explore the technique of implantation of double-J stent via the guide-wire track, which was established through percutaneous renal puncturing, for the treatment of ureteral stricture and obstruction, and to evaluate its therapeutic effect. Methods A total of 75 patients with ureteral stricture or obstruction, who failed to respond to cystoscopic catheterization, were enrolled in this study. The lesions included benign stricture(n=60) and malignant stricture(n=15). Ureteral guide-wire track was established through percutaneous renal puncturing, which was followed by the dilatation of the stricture with balloon catheter and subsequent implantation of double-J stent via the guide-wire track. After the double-J stent was removed, the patients were followed up for 3 months to five years. Results The success rate of the procedure was 98.7%(74/75). Technical failure occurred in one patient with benign ureteral stricture. The cure rate was 70.7%(53/75), the improvement rate was 26.7%(20/75), and no improvement was seen in one case (1.35%). The total effective rate was 97.3%(73/75). Conclusion For the treatment of ureteral stricture and obstruction, the implantation of double-J stent via the guide-wire track, which is established through percutaneous renal puncturing, is a safe and effective method.
ABSTRACT
Objective To investigate the therapeutic effect of modified transperitoneal laparoscopic dismembered pyeloplasty in children with with ureteropelvic junction obstruction (UPJO).Methods The clinical data of 27 children with UPJO treated with transperitoneal laparoscopic dismembered pyeloplasty were analyzed retrospectively.The age ranged from 5 to 104 months (mean,37 months).All cases were diagnosed by ultrasonography,IVU,CT and/or renal radionuclide scanning.The antero-posterior pelvic diameter was more than 3 cm by ultrasound in all cases.Indications of surgery were as followings:symptoms of upper abdominal pain or low back pain and/or split renal function ＜40％ and/or progressive dilatation.Modified transperitoneal laparoscopic dismembered pyeloplasty was performed.Double hitch stitches were transfixed at the top of pelvis and ureter to be anastomosed,and a 6 F urethral catheter was inserted as a ureteral stent percutaneously through the puncture hole and was removed 7-9 days postoperatively without double-J stent.Results All operations were completed laparoscopically without conversion to open surgery.The mean operative time was 118 min (range,85 to 176),the mean blood loss was 16 ml (range,10 to 30) and the mean postoperative hospital stay was 10.5 days (range 9 to 13).The perinephric urine drainage occurred in 2 patients with about 200 ml/d,and reduced to 6 ml/d and 4 ml/d 5 to 6 days after operation.During the follow-up period for 12 to 36 months(mean,22 months) in 27 cases,there was no stricture at UPJ and the hydronephrosis reduced significantly or disappeared.Conclusion Laparoscopic dismembered pyeloplasty with double hitch stitches and an ordinary urethral catheter as an ureteral stent is an easy method with high successful rate and less operative time,which avoids reoperation to remove the double-J stent and is worthy of clinical popularization.
ABSTRACT
La instalación de catéteres ureterales tipo Doble J o pigtail es una práctica habitual en urología, el principal problema de su instalación radica en que gran parte de los pacientes presentan diferentes tipos de molestias en relación a su uso. Existen algunas alternativas de tratamiento médico que han probado ser efectivas en disminuir parcialmente estos síntomas; sin embargo, pocos estudios han evaluado la posibilidad de terapias locales, y estos reclutaron pocos pacientes por lo que no pudieron demostrar grandes diferencias.
The use of Double J ureteral stents or also called pigtail is common practice in urology; the main problem with its use is that a large number of patients develop discomfort with indwelling stents. To diminish them there are medical treatments that have been proven useful, however, few studies have assessed local therapies, and this studies include a small number of patients.

Objective To evaluate the clinical effect of placing double J stent using a ureteroscope in early managing ureterovaginal fistula.Methods Twenty-eight patients cases with ureterovaginal fistula from 2002 to 2008 were treated early with placing double J stent using a ureteroscope and the clinical data were reviewed.Results Twenty-two of 28 cases were treated and double J stent was placed in them by a uretero-scope and 75% (21/28)of cases were cured.Four of 21 cases were treated twice by a ureteroscope and were cured finally.7 cases with failure ureterovaginal treatment underwent ureterocystostomy and were cured.The follow-up from 6 months to 33 months (average 10.1±6.4 months)showed that all of the 28 cases had been cured and had no urinary fistula.Conclusion Placing double J stent using a ureteroscope is the first choice of operative procedure for the early treatment of ureterovaginal fistula.
ABSTRACT
Presentamos el caso de un paciente de 61 años, con historia de urolitiasis a repetición. Luego de la instalación de catéteres doble J en forma bilateral, se pierde de controles reapareciendo luego de 14 años. El estudio imagenológico demuestra una nefrolitiasis coraliforme completa izquierda y parcial a derecha, asociada a incrustación de ambos catéteres. Describimos el manejo exitoso de los catéteres incrustados asociados a litiasis, que requirieron una aproximación endourológica a través de cirugía percutánea. La nefrolitotomía percutánea permite el manejo exitoso de un catéter severamente incrustado asociado a una masa de cálculos, incluso en aquellos casos bilaterales.
We review our recent experience with encrusted retained ureteral stents associated with a large stone burden in a patient of 61 years old as well as current endoscopic options available for management. We described the successful management of a retained encrusted stent with endourological procedures. Percutaneous nephrolithotomy is a good option for treating a severely encrusted stent and the associated stone burden.
