Tratamiento endourológico de la litiasis ureteral lumbar. ¿Qué aporta la ureterorrenoscopia flexible?

Introduction and objectivesCurrently, there are no established criteria regarding treatment for lumbar ureteral stones. The objective of this work is to present our results in the endourological treatment of this pathology, analyzing the variables associated with the use of the flexible ureterorenoscope.Material and methodsRetrospective review of 103 patients who underwent retrograde URS with semi-rigid or flexible ureterorenoscope. Proximal location: L2-L3. Medial location: L4-L5. Semirigid URS was the initial treatment, with conversion to flexible URS when it was required to complete the procedure. Success was defined as absence of residual fragments (6 weeks). Demographic, surgical, immediate postoperative variables, and those related to the stone, were analyzed. Their correlation with the use of the flexible ureterorenoscope was evaluated.ResultsMean age: 57.2 years (SD 15.6); there were 73 men (70.9%). Stone size: 8 mm (range 4-30; IQR 4.5). Proximal location: 58 (56.3%). Previous JJ: 44.7%. Previous nephrostomy: 10.7%. Semirigid URS with conversion to flexible URS: 51 (49.5%). Impacted stones: 28.2%. Intraoperative complications: 2 (1.9%). Postoperative JJ: 84.5%. Immediate postoperative complications: 23 (22.3%) (Clavien-Dindo I-II: 91.3%). Postoperative ureteral stricture: 5.8%. Success: 88.4%. Residual fragments: 12 (11.7%). Spontaneous passage: 6 (50%). Greater performance of flexible URS in proximal ureteral stones (P = 0.001) of more than 11 mm (P = 0.02) in univariate analysis, and in proximal stones [OR 3.5; 1.5-8.1; P = 0.004] in multivariate analysis.ConclusionsEndourological treatment obtained a high success rate in our sample. Size greater than 11 mm and proximal ureteral location in univariate and multivariate analysis, respectively, behaved as predictors of flexible URS.     

Comparison between Antegrade versus Retrograde Ureteral Stent Placement for Malignant Ureteral Obstruction

PurposeTo compare the technical success of antegrade uteral stent (AUS) and retrograde ureteral stent (RUS) placements in patients with malignant ureteral obstruction (MUO) and to determine the predictors of technical failure of RUS.Materials and MethodsThis study retrospectively included 61 AUS placements (44 patients) performed under fluoroscopic guidance and 76 RUS placements (55 patients) performed under cystoscopic guidance in patients with MUO from January 2019 to December 2020. Technical success rates of the 2 techniques were compared using inverse probability of treatment weighting (IPTW) analysis. Logistic regression was used to identify predictive factors for technical failures.ResultsTechnical success was achieved in 98.4% of the AUS group and 47.4% of the RUS group. After stabilized IPTW, the technical success rate was higher in the AUS group than in the RUS group (adjusted risk difference, 49.4%; 95% confidence interval [CI], 35.4%–63.1%). The independent predictors for technical failure of the RUS procedure were age of ≥65 years (odds ratio [OR], 5.56; 95% CI, 1.73–21.27), ureteral orifice invasion (OR, 4.21; 95% CI, 1.46–13.46), and extrinsic cancer (OR, 15.58; 95% CI, 2.92–111.81).ConclusionsThe technical success rate of AUS placement was higher than that of RUS placement in patients with MUO. RUS failure was associated with age of ≥65 years, cancer with ureteral orifice invasion, and extrinsic ureteral obstruction.     

The Ilizarov method for the treatment of complex tibial fractures and non-unions in a mass casualty setting: the 2005 earthquake in Pakistan

We report our experience in treating victims of the recent earthquake disaster in Pakistan. Our experience was based on two humanitarian missions to Islamabad: one in October 2005, 10 days after the earthquake, and the second in January 2006. The mission consisted of a team of orthopaedic surgeons and a second team of plastic surgeons. The orthopaedic team bought all the equipment for application of Ilizarov external fixators. We treated patients who had already received basic treatment in the region of the disaster and subsequently had been evacuated to Islamabad. During the first visit, we treated 12 injured limbs in 11 patients. Four of these patients were children. All cases consisted of complex multifragmentary fractures associated with severe crush injuries. All fractures involved the tibia, which were treated with Ilizarov external fixators. Nine fractures were type 3b open injuries. Eight were infected requiring debridement of infected bone and acute shortening. During a second visit, we reviewed all patients treated during our first mission. In addition, we treated 13 new patients with complex non-unions. Eight of these patients were deemed to be infected. All patients had previous treatment with monolateral fixators as well as soft tissue coverage procedures, except one patient who had had an IEF applied by another team. All these patients had revision surgery with circular frames. All patients from both groups were allowed to fully weight-bear post-operatively, after a short period of elevation to allow the flaps to take. Overall, all fractures united except one case who eventually had an amputation. Four patients had a corticotomy and lengthening, and three of them had a successful restoration of limb length. The fourth patient was the one with the eventual amputation.     

The efficacy and safety of ureteral dilation and long-term type ureteral stent for patients with ureteral obstruction

ObjectiveThis study was conducted to investigate the efficacy and safety of ureteral dilation and placement of a long-term ureteral stent for patients with various types of ureteral obstructions.MethodsWe retrospectively reviewed the records of 39 patients presenting with ureteral obstruction secondary to malignant strictures (n = 9) or nonmalignant strictures (n = 30). The mean age of these patients was 55.8 ± 16.1 years (range, 13–87 years). All patients underwent retrograde ureteral balloon dilation and placement of one to three ureteral stents. Stent patency rate and complications including febrile urinary tract infection, stent encrustation, and stent fragmentation were recorded.ResultsA total of 117 ureteral stents were implanted during the 83 procedures. Three stents were placed in seven patients and two stents in 20 patients. The patency rate was 95.2% with a mean 75-day follow-up. There was no encrustation in 104 stents and Grade 1 in 13 stents. The patency rate was similar between the patients with malignant strictures and those with nonmalignant strictures (100% vs. 94.7%, p = 0.57). However, three episodes of febrile urinary tract infection were noted only in patients with malignant strictures. The improvement of hydronephrosis and complications were also comparable between those patients with ureteral stents indwelling for >90 days and those for <90 days. No stent fragmentation was found in any of the patients.ConclusionWe demonstrated that ureteral dilation and placement of a single or multiple ureteral stents was effective and safe for patients with ureteral obstruction.
