RESUMO

A 74-year-old woman was transported to an emergency room of a general hospital with sudden left flank pain. After examination, the pain was attributed to left hydronephrosis resulting from left retroperitoneal fibrosis (RF). The pain and renal function improved after left ureteral stenting. Four months after the transportation, she was referred to our hospital for further examination. Her renal function deteriorated again despite successful release of ureteral obstruction. Consequently, the left kidney developed end-stage renal dysfunction at 15 months after symptom onset. Pathological examination of the left dysfunctional kidney removed by laparoscopic surgery to avoid infectious pyelonephritis revealed numerous IgG4-positive plasma cells invading the renal parenchyma. The pathological findings suggested that the renal dysfunction was due to IgG4-related tubulointerstitial nephritis (IgG4-TIN) rather than ureteral obstruction. In the case of RF with decreased renal function, not only retroperitoneal lesion biopsy but also renal biopsy should be considered to diagnose IgG4-TIN and start steroid treatment if necessary.

RESUMO

A 41-year-old female who suffered local recurrence of cervical cancer after receiving chemoradiotherapy underwent radical hysterectomy, radical vaginal resection, and pelvic and paraaortic lymph node dissection. After surgery, bilateral hydronephrosis due to right ureteral stenosis and left uretero-vaginal fistula occurred. We therefore placed a bilateral ureteral stent. Thereafter, we continued to replace the bilateral ureteral stent once every 3 months, but the replacement of the right ureteral stent became impossible three years after the initial placement. We thus performed bilateral upper urinary tract reconstruction using an ileal ureter with the aim of both eliminating the left ureteral vaginal fistula and resolving the right ureteral stricture.

RESUMO

A 53-year-old man presented with lower urinary tract symptoms and recurrent urinary tract infections since last 3 years without being investigated or treated properly. Examination revealed a hard mobile lump in the pelvis, and blood investigations showed raised serum creatinine of 2.9 mg/dL. Subsequent urgent ultrasound scan showed a large urinary bladder stone with bilateral hydroureteronephrosis, and X-ray kidney, ureter and bladder demonstrated a 9 cm×6 cm elliptical radio-opaque shadow in the pelvis. He underwent emergency admission followed by open cystolithotomy on the next day. He was discharged after 48 hours with a urethral catheter. After 2 weeks, his renal function recovered completely; repeat ultrasound scan revealed complete resolution of hydronephrosis. Urethral catheter was removed following a normal cystogram. Uroflowmetry after 6 weeks revealed underlying bladder outlet obstruction, and he was started on alpha blocker which improved his urinary flow.

RESUMO

Robotically assisted laparoscopic techniques may be used for proximal and distal ureteral strictures. Distal strictures may be approached with ureteroneocystotomy, psoas hitch, and Boari flap. Ureteroureterostomy, buccal mucosa graft ureteroplasty, and appendiceal flap ureteroplasty are viable techniques for strictures anywhere along the ureter. Ileal ureteral substitution is reserved for more extensive disease, and autotransplantation is reserved for salvage situations.

RESUMO

Almost 30 years have passed since the inception of minimally invasive surgery in urology and specifically in pediatric urology. Laparoscopy has now become an essential tool in the pediatric urologic armamentarium. The application of robot-assisted surgery in pediatrics has allowed for widespread utilization for common reconstructive procedures such as pyeloplasty and ureteral reimplantation. Understanding the implementation, technical considerations, and outcomes are critical for continued success and adoption. This has allowed for increased use in more complex urologic procedures such as redo pyeloplasty, dismembered ureteral reimplantation, catheterizable channel creation, and bladder augmentation.

RESUMO

PURPOSE: Encrustation is a common phenomenon that can occur following placement of a ureteral stent into the urinary tract, and it can lead to serious complications. The following review addresses the mechanism of encrustation, the management of these stents and the newest technology developed to mitigate this issue. MATERIALS AND METHODS: We performed a comprehensive literature search on stent encrustation including peer-reviewed publications, public product listings, and material on current and future stent technology. RESULTS: The mechanism of encrustation is complex and multifaceted, including dwell time, patient specific risk factors, conditioning film formation, biofilm formation and mineral deposition. Several technological developments in stent materials and coatings may have a role in reducing the risk of stent encrustation. It is important to identify the extent of stent encrustation and plan treatment strategies accordingly. We propose a novel treatment algorithm for the management encrusted ureteral stents. CONCLUSIONS: The ubiquity of ureteral stents in urology practice mandates updated knowledge about the prevention of stent encrustation, identification of high risk patients and preparedness for removal using multimodal techniques.

RESUMO

INTRODUCTION: Distal ureter strictures are complications of surgical interventions for obstetric, gynecological, urological, vascular and oncological diseases. Reconstructive plastic correction of these strictures is a complex urological procedure. The choice of a technique is associated with the localization and extent of the stricture. Boari flap ureteroneocystostomy is one of the main operations to choose from. Its implementation in open and laparoscopic versions in recent history required special analysis. OBJECTIVE: to analyze the experience of ureteral reimplantation according to the Boari technique with a detailed description of its open and laparoscopic approaches. MATERIALS AND METHODS: In 2010-2019, 30 patients underwent surgery using the Boari technique. 17 patients underwent open surgery (group 1) and 13 patients underwent surgery using laparoscopic techniques (group 2). A comparative analysis of the two groups was carried out considering clinical and intraoperative data. Complications were studied, as well as immediate and long-term results with a follow-up period of 6-120 months. RESULTS: Patients of the two groups showed similar clinical characteristics. Patients had an equal extent of lesion in the groups (p>0.05). However, the lesions were located more proximally from the bladder in group 1, which required the use of longer flaps (p=0.024). Blood loss volume was identical, and the duration of laparoscopic operations was significantly shorter (p=0.019). Postoperative complications occurred in 26.7% of cases in the next 3 months, which required a temporary percutaneous puncture nephrostomy (IIIa degree according to Clavien-Dindo) in 2 cases and conservative therapy (II degree according to Clavien-Dindo) in 6 cases. Clinical vesicoureteral reflux was determined in only one case during a one-year follow-up period. CONCLUSION: Open and laparoscopic Boari techniques have an equally high ureteral recovery efficiency without the need for a re-operation in all cases. Refluxing flap ureteral anastomosis is extremely rarely accompanied by a clinic of vesicoureteral reflux. The ureter can be restored using a laparoscopic Boari technique in all cases.

RESUMO

PURPOSE: To develop a model for simulated training of ureteropyelic anastomosis in laparoscopicpyeloplasty. METHODS: Longitudinal and experimental study, with 16 participants. A synthetic instrument was produced to simulate the renal pelvis and the proximal portion of the ureter positioned on a platform within laparoscopic simulators, thereby resulting in the realistic simulation of the ureteropelvic anastomosis. A step-by-step guide was also developed for the accomplishment of the ureteropelvic anastomosis training model. RESULTS: In the evaluation of all participants' suture training, a decrease was found in the time needed to perform the anastomosis, with a median of 17.83 min in the 1st step and 14.21 min in the last one (p = 0.01). Regarding the knots, in the 1st step, 5% of them were considered firm, with an evolution to 30% in the last step (p = 0.011). CONCLUSION: We noticed improvement in the ability to perform the ureteropelvic anastomosis by participants with no experience with it. Therefore, even unexperienced participants can improve their skills with this training. Moreover, we observed the effectiveness of the model use, confirmed by the participants' opinion and its validation by expert surgeons.

RESUMO

A 50-year-old female presented to our department of urology with nephrostomy drain in the right kidney been placed because of an acute obstructive pyelonephritis. Nephrostogram revealed an intra-renal pelvis with no passage of contrast into the ureter. Retrograde pyelography identified the extended ureteric stricture and need for a substitution. Laparoscopic ileocalicostomy was performed to achieve a communication between the lower calyx and bladder. Video describing surgical technique is available on https://youtu.be/bIW_m3lwXWY. Due to thick and full-blooded renal parenchyma, a partial nephrectomy of the lower pole had to perform to get an access to the renal calyx. It took 25 min of warm ischemia. At that, sutures of renorrhaphy should have provided reliable hemostasis on the one hand, and free outflow of urine via an isolated calyx on the other. To reduce the length of ileoureter a bladder psoas hitch maneuver was used. A 25-cm-long segment of ileum was isolated and rotated in isoperistaltic manner. Double J stent was held through it. Ileocalicostomy by interrupted and ileovesicostomy by continuous sutures were performed one after another. There were no intraop complications. OR time - 300min. EBL - 200ml. Postoperative course was uneventful. Ten days after surgery, nephrostogram and cystography confirmed the patency of the neoureter and the tightness of both anastomoses. Nephrostomy drain was removed first, ureteral - one day after. "JJ" stood for 3 weeks. The patient is doing well at more than 12 months of follow-up with a stable renal and ileoureteral function. In comparison with open procedure our surgery is significantly less invasive, per contra robotic - not so expensive. As far as we known, this is the first case report of conventional laparoscopic intracorporeal ileocalicostomy with long-term good functional results demonstration.

RESUMO

PURPOSE: We present a new approach for urine drainage in pediatric patients following laparoscopic pyeloplasty, the trans-uretero-cystic external urethral stent (TEUS). METHODS: We retrospectively identified 85 children who underwent laparoscopic pyeloplasty from July 2015 to June 2017. The included children were assigned to group A (double-J stent) or group B (TEUS). In group A, the double-J stent was removed by a cystoscopy under anesthesia after 1 month, while in group B, the external stent was removed after 5 to 7 days. We examined the durations of operation, hospital stay and the frequency of stent-related complications including urinary leakage, stent dislocation, stent occlusion, and urinary tract infection. RESULTS: The operation time was significantly longer for patients in group B than for those in group A. No significant difference was observed between the groups regarding stent-related complications. In group A, 4 patients need auxiliary stent re-insertion for the management of complications, 2 developed urinary tract infection, and 2 had stent occlusion. In group B, none needed auxiliary stent re-insertion for complications and avoided re-operation. CONCLUSIONS: In children, the outcome of external stent implantation was similar to that using double-J stent, and the use of the former approach may be beneficial for younger children.

RESUMO

OBJECTIVE: To summarize the initial clinical experience and follow-up results of the treatment for ureteroileal anastomotic stricture after radical cystectomy with Allium coated metal ureteral stent. METHODS: From September 2018 to September 2019, 8 patients with ureteroileal anastomotic stricture after radical cystectomy underwent Allium ureteral stent insertion in Peking University People's Hospital and People's Hospital of Daxing District. The preoperative renal pelvis width under ultrasound was collected to evaluate the postoperative hydronephrosis, creatinine and urea nitrogen (BUN) before and after surgery, perioperative infection, and stent-related complications. The serum creatinine and BUN, renal pelvis width under ultrasound, urography and abdominal plain film (KUB) were reviewed at the end of 1, 3, and 6 months and annually postoperatively to observe the stent position and morphology. The long-term stent patency rate, complication rate, renal function and hydronephrosis were followed up and analyzed. The t-test or rank-sum test was used to compare the measurement data of the matched sample from the preoperative to the last follow-up. RESULTS: In the study, 6 cases (7 sides) were ureteral ileal conduit stricture, and 2 cases (3 sides) ureteral orthotopic neobladder stricture. Before surgery, 5 patients underwent long-term indwelling of a single J ureteral stent, with an average indwelling time of (20.6±8.8) months and an average replacement frequency of (3.6±1.3) months/time. The mean width of renal pelvis was (26.5±9.1) mm on preoperative renal ultrasonography. Among them, 6 patients were successfully indwelled with Allium coated metal ureteral stent by retrograde approach, and 2 patients by combination of double-endoscopy and ante-retrograde approach. No surgery-related complications during perioperative period were observed. The mean follow-up period was 9.8 months and Allium stent and ureter remained unobstructed in all the patients at the last follow-up without replacement or removal. Compared with preoperative data, the mean width of renal pelvis and mean blood urea nitrogen (BUN) in the last follow-up period were significantly reduced [(26.5±9.1) mm vs. (13.4±2.5) mm, P=0.008; (11.6±2.3) mmol/L vs. (10.2±2.2) mmol/L, P=0.017], however, there were no significant differences in the average serum creatinine or hemoglobin (P>0.05). Ureteroileal anastomotic re-stricture and other stent-related complications were not observed in all the patients by antegrade urography. CONCLUSION: Allium coated metal ureteral stent could be used for the treatment for ureteroileal anastomotic stricture, which could maintain relatively long-term patency rate and protect renal function. The indwelling time was longer and it could improve quality of life of patients.

RESUMO

Ureteropelvic junction obstruction (UPJO) is characterized by decreased flow of urine down the ureter and increased fluid pressure inside the kidney. Open pyeloplasty had been regarded as the standard management of UPJO for a long time. Laparoscopic pyeloplasty reports high success rates, for both retroperitoneal and transperitoneal approaches, which are comparable to those of open pyeloplasty. However, open and laparoscopic pyeloplasty have yielded disappointing failure rates of 2.5%-10%. The main causes for recurrent UPJO are severe peripelvic and periureteric fibrosis due to urinary extravasation, ureteral ischemia, and inadequate hemostasis. In addition, failing to diagnose lower pole crossing vessels before or during the primary procedure is also responsible for recurrent UPJO. In addition, poor preoperative split renal function, hydronephrosis, presence of renal stones, patient age, diabetes, prior endopyelotomy history, and retrograde pyelography history were considered as predictors of pyeloplasty failure. The failure is usually defined by persistent pain, persistent radiographic obstruction (infection or stones), continued decline in split renal function, or a combination of the above. And the failure of pye-loplasty often occurs in the first 2 years after the surgery. The available options for managing recurrent UPJO with a salvageable renal unit include endopyelotomy, re-do pyeloplasty, stent implantation, percutaneous nephrostomy, ureterocalicostomy, and nephrectomy. Re-do pyeloplasty has such merits as high successful rates and rare complications, compared with endopyelotomy or ureterocalicostomy. And some investigators think that re-do pyeloplasty should be regarded as the gold standard for secondary therapy if feasible. Open pyeloplasty can enlarge the operating field, facilitate the exposure of the ureteropelvic junction, reduce the difficulty of operation, and thus reduce the occurrence of complications. There are no significant differences among the success rates of re-do pyeloplasty under open approach, traditional laparoscopy and robot-assisted laparoscopy, according to previous reports. However, traditional laparoscopic and robot-assisted pyeloplasty give advantages of cosmetology, small trauma, less postoperative pain, speedy recovery and shorter hospitalization, fewer complications and lower recurrent rates. If the primary pyeloplasty is an open operation in retroperitoneal approach, the traditional laparoscopic and robotic operation with retroperitoneal approach should be considered for secondary repair. The cause of recurrent UPJO should be evaluated before surgery and identified intraoperatively to minimize the possibility of recurrence.

RESUMO

OBJETIVO: Analizar si la aplicación de la cirugía laparoscópica en el tratamiento de la estenosis pieloureteral (EPU) ha sido beneficiosa para el paciente pediátrico. MATERIAL Y MÉTODO: Hemos revisado de forma retrospectiva las historias clínicas de todos aquellos pacientes intervenidos de EPU desde enero de 1997 hasta diciembre de 2017. Se excluyeron las que tuvieron seguimiento menor a 6 meses, y las cirugías videoasistidas. Se han comparado la cirugía abierta con la cirugía laparoscópica. Se han recogido los siguientes datos: abordaje quirúrgico, necesidad y tipo de derivación urinaria, tiempo quirúrgico, estancia media, complicaciones, tasa de reestenosis. Los parámetros ecográficos y del renograma diurético también han sido recogidos. RESULTADOS: Se han analizado 328 pieloplastias, 142 se realizaron laparoscópicamente. La tasa de éxito global ha sido del 96,6%, existiendo un 11,9% de complicaciones, sin existir diferencias significativas entre la cirugía abierta y la laparoscópica. En el 97,5% de las cirugías, la orina se derivó mediante catéter nefroureteral externo, catéter doble J o catéter tipo Salle, existiendo diferencias entre cirugía abierta y laparoscópica. El tiempo quirúrgico medio fue significativamente superior en la cirugía laparoscópica. La estancia media fue menor en el grupo de cirugía laparoscópica de forma significativa. CONCLUSIÓN: La vía de abordaje no es un factor que influya en el éxito de la cirugía de la EPU, por ello pensamos que la cirugía laparoscópica es la técnica de elección en pacientes pediátricos


OBJECTIVE: To analyze whether the application of laparoscopic surgery in the treatment of pyeloureteral junction obstruction (PUJO) has been beneficial for pediatric patients. MATERIALS AND METHODS: Medical records of all patients undergoing PUJO surgery from January 1997 to December 2017 were retrospectively reviewed. Patients with < 6-month follow-up and patients undergoing video-assisted surgery were excluded. Open surgery was compared with laparoscopic surgery. The following data were collected: surgical approach, need for and type of urinary diversion, operating time, mean hospital stay, complications, and restenosis rate. Ultrasound and diuretic renogram parameters were also retrieved. RESULTS: 328 Anderson-Hynes pyeloplasties were analyzed, 142 of which had been performed laparoscopically. Overall success rate was 96.6%, and complication rate was 11.9%. No significant differences were noted between open and laparoscopic surgery. In 97.5% of surgeries, urine was diverted using an external nephroureteral catheter, a double J stent, or a Salle stent, with significant differences between open and laparoscopic surgery. Mean operating time was significantly longer in laparoscopic surgery. Mean hospital stay was significantly shorter in the laparoscopic surgery group. CONCLUSION: Surgical approach does not play a role in PUJO surgery success. Therefore, in our view, laparoscopic surgery should be the technique of choice in pediatric patients

RESUMO

INTRODUCTION: Transurethral endopyelotomy is an alternative treatment method for short stricture of ureteropelvic junction (UPJ). AIM: to evaluate the efficiency of transurethral thulium laser endopyelotomy. MATERIALS AND METHODS: A total of 94 patients with UPJ obstruction during the period from December 2016 to December 2018 were prospectively enrolled in the study. Pelvic size did not exceed 3 cm in 31 patients, and it was in the range from 3 to 4 cm and more than 4 cm in 35 and 28 cases, respectively. Depending on the treatment, all patients were divided into 2 groups. The main group included 48 patients who underwent retrograde thulium fiber laser endopyelotomy. In the control group (n = 46), patients underwent Anderson-Hynes laparoscopic pyeloplasty. In the main group, there were significantly more patients with more preserved ipsilateral kidney function, with short (less than 1 cm) and recurrent UPJ strictures and less severe hydronephrosis compared to the control group. In addition, there were no patients with crossing vessel in the main group. Postoperatively, an internal stent of 6-8 Fr was put in all patients for a period of 6-8 weeks. After stent removal, all patients underwent a follow-up examination, including an ultrasound examination and, if pelvic size was more than 3 cm, contrast-enhanced CT-urography was performed. RESULTS: In all patients, after stent removal, a decrease in the pelvic size was noted. The operation time in the main and control group was 24+/-14 minutes and 82+/-26 minutes, respectively. In all cases, ureteropyeloscopy was performed prior to laparoscopy to determine the exact length of stricture and to exclude narrowing of other parts of the ureter. After follow-up of 24 months, an examination in 36 patients of the main group and 29 patients of the control group was performed. There was 1 recurrence after laparoscopic pyeloplasty and 1 recurrence after endopyelotomy. In other patients of both groups, there were neither stricture, nor impaired renal function. CONCLUSION: The first experience of using a thulium fiber laser for transurethral endoscopic treatment of UPJ obstruction is presented in the article. Indications for the transurethral thulium endopyelotomy are the presence of primary or secondary UPJ obstruction (with a decrease in kidney function by no more than 40%), length of up to 1 cm, absence of an additional vessel and pelvic dilatation of no more than 4 cm.

RESUMO

PURPOSE: Obstructive pyelonephritis is considered a urological emergency but there is limited evidence regarding the importance of prompt decompression. We sought to investigate whether delay in decompression is an independent predictor of in-hospital mortality. Secondarily, we aimed to determine the impact of patient, hospital and disease factors on the likelihood of receipt of delayed vs prompt decompression. MATERIALS AND METHODS: Using the National Inpatient Sample from 2010 to 2015, all patients 18 years old or older with ICD-9 diagnosis of urinary tract infection who had either a ureteral stone or kidney stone with hydronephrosis (311,100) were identified. Two weighted sample multivariable logistic regression models assessed predictors of the primary outcome of death in the hospital and secondly, predictors of delayed decompression (2 or more days after admission). RESULTS: After controlling for patient demographics, comorbidity and disease severity, delayed decompression significantly increased odds of death by 29% (OR 1.29, 95% CI 1.03-1.63, p=0.032). Delayed decompression was more likely to occur with weekend admissions (OR 1.22, 95% CI 1.15-1.30, p <0.001), nonwhite race (OR 1.34, 95% CI 1.25-1.44, p <0.001) and lower income demographic (lowest income quartile OR 1.25, 95% CI 1.14-1.36, p <0.001). CONCLUSIONS: While the overall risk of mortality is fairly low in patients with obstructing upper urinary tract stones and urinary tract infection, a delay in decompression increased odds of mortality by 29%. The increased likelihood of delay associated with weekend admissions, minority patients and lower socioeconomic status suggests opportunities for improvement.

RESUMO

OBJECTIVE: Polar vessels are related with pyelo-ureteral stenosis (PUE) in 5-10% of the patients. In the 24% of these cases an intrinsic cause of stenosis can also be found. An increased incidence of polar vessels is found in laparoscopic surgery, compare to open procedures. Our study analyses this difference in our hospital, studying its influence in the aetiology of the disease.MATERIAL AND METHODS: Descriptive and retrospective study of patients operated in our hospital of pyeloplasty, because of PUE between 2009 and 2017. Patients have been divided in two groups: operated by laparoscopy (PL), or operated by conventional surgery (PA). All cases in which polar vessels were seen in TC where excluded. Each group included 47 patients. RESULTS: We found no statistical differences in the age of surgery of the two groups (36,1±41,3 months PL/31,8±37,2 months PA; p=0.527). Overall, 18 polar vessels were found, 15 in PL and 3 in PA. 6 patients of the PA group presented recurrence of the obstruction, and in 2 of them, polar vessels were found in the second surgery. All the 18th cases presented anomalies in the histological study related with inflammation or fibrosis. CONCLUSIONS: The laparoscopic approach allows a better vision of crossing vessels in the cases of extrinsic PUE. Dismembered pyeloplasty might be the best treatment, as an intrinsic cause of obstruction cannot be ruled out according to the observed histological alterations.

RESUMO

OBJETIVO: La incidencia de vasos polares como causa de estenosis pielo-ureteral (EPU) es del 5-10%. En un 24% de los casos asocia, además, una estenosis intrínseca. La aplicación de la laparoscopia para la realización de la pieloplastia ha aumentado significativamente la detección de cruces vasculares respecto a la cirugía abierta. El objetivo del estudio es analizar esta diferencia en nuestro centro, valorando su repercusión en el cuadro de obstrucción. MATERIAL Y MÉTODOS: Estudio descriptivo y retrospectivo de pacientes intervenidos mediante pieloplastia por EPU entre 2009 y 2017. Los pacientes se han dividido en dos grupos: intervenidos por vía laparoscópica (PL) o por cirugía abierta (PA), excluyéndose los casos diagnosticados previamente de vaso polar. La muestra incluyó un total de 94 pacientes, 47 en cada grupo. RESULTADOS: No se han encontrado diferencias estadísticamente significativas en la edad de intervención de ambos grupos (36,1±41,3 meses PL/31,8±37,2 meses PA; p = 0,527). Se detectaron 18 vasos polares en total, 15 en PL y 3 en PA. 6 pacientes del grupo PA presentaron recidiva de la obstrucción y 2 de ellos presentaron cruces vasculares no detectados en la primera cirugía. En los 18 casos se encontraron alteraciones histológicas de tipo inflamatorio/fibrosis. CONCLUSIONES: La laparoscopia ofrece una visión mas detallada de la vascularización del riñón, permitiendo una mayor detección de vasos polares frente a la PA. La pieloplastia desmembrada constituye el tratamiento con mejores tasas de éxito, pues no se puede descartar un componente intrínseco obstructivo, además de la compresión vascular
