Comparison of water vapor thermal therapy and prostate artery embolization for fragile patients with indwelling urinary catheters: Preliminary results from a multi-institutional study.

PURPOSE: To report our preliminary experience with water vapor thermal therapy with the Rezum™ System and Prostate Artery Embolization (PAE) for treatment of medically refractory, complete urinary retention to achieve successful cessation of catheter dependency in frail-patients. PATIENTS AND METHODS: A multi-institutional study was conducted including all patients who underwent Rezum™ procedure and PAE between October 2017 and June 2020. The included population focused on frail-patients unsuitable for conventional surgery with complete urinary retention. Rezum™ patients were identified and matched (1:1) with patients who underwent PAE. The matching criteria were age, Charlson score, prostate volume and duration of follow-up. The primary outcome was catheter-free survival, defined as spontaneous voiding and release from catheter dependence. RESULTS: Eleven patients from the Rezum™ group were matched to 11 embolized patients. PAE and Rezum™ patients were comparable in age (median: 77 vs. 75 years), Charlson score (median: 6 vs. 6) and prostate volume (74 vs. 60 cc). Procedures were significantly longer in the PAE group compared to the Rezum™ procedures (median: 148 vs. 8min, P<0.001). After a median follow-up of 12 months, spontaneous voiding was conserved in all cases (100%) after the Rezum™ procedure and in 5 cases (45.4%) after PAE (P=0.01). In catheter-free patients, the rate of benign prostatic hyperplasia medication use after procedure was 40% for PAE and 18.2% for Rezum™ patients (P=0.54). CONCLUSIONS: Our preliminary experience for treatment of complete urinary retention in frail-patients shows the feasibility of PAE and Rezum™ to restore spontaneous urination without being associated with the occurrence of major complications. Early data suggests that Rezum™ may provide superior results in terms of cessation of catheter dependence. Future studies are needed to definitively assess which treatment would be best suited for each patient. LEVEL OF EVIDENCE: 3.

Holmium laser enucleation and water vapor thermal therapy for the treatment of symptomatic benign prostatic hyperplasia: A cost analysis.

PURPOSE: To perform a cost analysis of the current gold standard operation of Holmium Laser Enucleation of the prostate (HoLEP) compared to the new technique of water vapor thermal therapy with the Rezum™ system for the treatment of symptomatic benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: Between October 2017 and January 2020, consecutive patients with invalidating lower urinary tract symptoms due to BPH who underwent Rezum™ and HoLEP procedures from the Aix regional hospital were identified. The outcome of each technique was assessed in terms of cost from the institutional perspective. Detailed expense reports based were provided by the accounts department of the hospital. These were used to compare in-hospital costs for each procedure. RESULTS: A total of 53 and 94 consecutive patients underwent respectively water vapor thermal therapy and HoLEP. The median costs for the surgical procedure were €1344 (IQR 1331-1361) and €669 (IQR 584-824), respectively for Rezum™ and HoLEP (median difference €675; P<0.001). The median costs of the hospital stay were €869 (IQR 869-869) for Rezum™ and €1295 (IQR 1295-1330) for HoLEP (median difference €426; P<0.001). Finally, the median total costs per patient were lower for HoLEP (€2005 [IQR 1902-2150]) than for Rezum™ (€2228 [IQR 2209-2243]) procedure, and the median difference of €233 was significant (P<0.001). CONCLUSIONS: One of the anticipated benefits of Rezum™, reduced length of hospital stay with an associated reduction in cost, did not materialize within this study. The patient's clinical condition and expectations should also be taken into account when deciding between Rezum™ and standard therapies. LEVEL OF PROOF: 3.

Treatment of benign prostate hyperplasia using the Rezum® water vapor therapy system: Results at one year.

PURPOSE: To report the results of convective radiofrequency (RF) water vapor thermal therapy in men with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) with one-year follow-up evaluation. MATERIAL AND METHOD: The study was conducted in 2 French hospitals, for men with moderate to severe LUTS secondary to BPH, as an alternative to classical surgery treatment. The pre- and postoperative evaluation of urinary symptomatology was based on the International Prostate Symptom Score (IPSS) questionnaire, measures of peak urinary flow rate (Qmax) and post-void residual volume (PVR). Erectile and ejaculatory functions were evaluated via the IIEF5 and MSHQ-ejd questionnaires. Rates of retreatment and complications were also reported. RESULTS: Sixty-two outpatients including 8 with urinary retention were treated. The median preoperative prostate volume was 47 (27-200) mL. At 6months postoperative, the IPSS had decreased significantly by 13.9 points (68.1%, P<0.001) and, at one year, by 12 points (61.5%, P<0.001). The quality of life (QoL) score at one year had decreased by 3.2 points (P<0.001) and the Qmax had improved by 6mL/s (P<0.001). All patients with urinary retention were weaned from bladder catheterization. No serious side effects (>Clavien II) were observed. No cases of de novo erectile dysfunction and an anejaculation rate of 10.8% was reported. The surgical retreatment rate at one year was 2.1%. CONCLUSION: The short-term results are encouraging, with significant efficacy on urinary symptoms and respect of sexual function. Nevertheless, it will be necessary to pursue the follow-up of this cohort to evaluate the mid-term and long-term evolution. LEVEL OF EVIDENCE: 3.

[The REVELA13 observatory to study new cases of bladder tumor among women living in Bouches-du-Rhône county]. / Rôle de l'observatoire REVELA13 dans l'épidémiologie des tumeurs de vessie des femmes dans les Bouches-du-Rhône.

INTRODUCTION: The REVELA13 observatory is a unique epidemiological tool listing the new cases of kidney tumors, bladder tumors and acute leukaemias in the Bouches-du-Rhône county (France). Aim was to exploit for the first time data from this observatory regarding new cases of bladder tumors≥T1 in women from 2012 to 2014. MATERIALS: This epidemiological study was observational and descriptive. Fifteen non-nominative variables from the REVELA13 database were analyzed in order to describe the clinical and pathological characteristics of the incident cases as well as their spatial and temporal distribution. The incidence rates expressed in new cases per year per 100000 inhabitants were standardized on the world age, calculated with 95 % confidence intervals and compared to national estimates for the same period. RESULTS: Incident bladder tumor cases were recorded in 291 women, corresponding to a standardized incidence on the world age of 3.85 [3.32-4.37] new cases per year per 100,000 population, 54 % higher than the national estimates of 2012 and 2015. Median age of diagnostic was 75.9 years. Sex ratio was 19.41 % (W/M). Tumors were predominantly non-muscle-invasive (52 %), high grade (69 %) and without associated carcinoma in situ (Cis) (49 %). The two most affected territories were Marseille and Aubagne-La Ciotat. CONCLUSION: The REVELA13 observatory has improved our epidemiological knowledge on female bladder tumors in Bouches-du-Rhône county and highlighted a local over incidence. LEVEL OF EVIDENCE: 3.

Tolerance of pain during transrectal ultrasound-guided biopsy of the prostate: risk factors.

Transrectal ultrasound-guided needle biopsy of the prostate is routinely performed to diagnose prostate cancer. We performed a prospective study to assess the pain and identify risk factors of pain during prostate biopsy. Prospectively, 131 patients were enrolled. Transrectal ultrasound-guided needle prostate biopsies were performed without any anesthesia. Pain was assessed by using an immediate postbiopsy anonymous questionnaire including a linear visual analog scale (VAS). Six factors were studied (age, prostate volume, cores number, operator, previous biopsy and first core location). Most of the patients tolerated the biopsy with acceptable discomfort. Among the risk factors studied, only first core location influenced the pain. Apex biopsy first was more painful. We recommend starting biopsy with the base.

[Ureteral replacement with non-modelled isoperistaltic ileoplasty]. / Remplacement urétéral par iléoplastie isopéristaltique non modelée.

OBJECTIVES: To study the long-term morbidity and efficacy of ureteroileoplasty in a retrospective series of 18 patients. MATERIALS AND METHODS: 12 men and 6 women with a mean age of 50 years underwent ureteroileoplasty with unilateral replacement in 15 patients and bilateral replacement in 3 patients. A total of 21 units renoureteral units were repaired by this technique. The pelvic ureter was replaced in 16 renoureteral units, the lumbar ureter was replaced in 1 case and the entire ureter was replaced in 4 cases. The commonest ureteral lesions were strictures secondary to ureteroscopy or ureterolithotomy (40%). All patients had normal renal function, except for one patient with serum creatinine of 224 mumol/l. RESULTS: With a mean follow-up of 25 months (range: 3 to 64 months) all ureteroileoplasties were patent with no major morbidity. Only the patient with preoperative renal failure developed hyperchloraemic acidosis with deterioration of her renal function. CONCLUSION: In the absence of renal failure, ureteroileoplasty is an operation with low morbidity achieving good medium-term results.

Fine-needle percutaneous biopsy of renal masses with helical CT guidance.

PURPOSE: To evaluate the feasibility, accuracy, and clinical role of fine-needle percutaneous biopsy of renal masses, with helical computed tomographic (CT) guidance. MATERIALS AND METHODS: In 63 patients (mean age, 62 years), 73 biopsies were performed. The median tumor size was 4.0 cm. Tumor biopsy was performed with an 18-gauge needle by using helical CT guidance in an outpatient setting. Two to four cores per tumor were obtained. RESULTS: Biopsy material was insufficient for analysis in 15 (21%) procedures. The median tumor size of failed or successful biopsies was 3.0 or 4.8 cm, respectively (P =.03). A benign lesion was found at eight biopsies. Two samples were suspicious for renal cell carcinoma (RCC). RCC was found in 38 biopsy samples. The remainder were transitional cell carcinoma, metastasis, lymphoma, or sarcoma. Twenty-six patients underwent nephrectomy. The accuracies of biopsy for histopathologic and Fuhrman nuclear grade evaluation were 89% and 78%, respectively. For tumors of 3.0 cm or smaller or larger than 3.0 cm, 37% (11 of 30) or 9% (four of 43) had failure of biopsy, respectively (P =.006). No substantial morbidity occurred. CONCLUSION: Fine-needle biopsy with helical CT guidance is accurate for the histopathologic evaluation of renal masses without morbidity. Indications are renal lesions that do not have the typical radiologic features of RCC, Bosniak category III or IV cystic lesions, and locally advanced or metastatic RCC.

Retrograde Acucise endopyelotomy: long-term results.

PURPOSE: We evaluated the long-term outcome of retrograde endopyelotomy with the Acucise cutting balloon as a first-line treatment of ureteropelvic junction obstruction (UPJO) in 36 patients (median age 44 years). PATIENTS: Twenty-three patients had a primary UPJO. The median follow-up in the series was 24 (6-42) months. RESULTS: Success, defined as a subjective and objective improvement, was obtained in 27 (75%). In multivariate analysis, only the presence of a crossing vessel (45% v. 81%) was a significant covariate for success. The success rates for primary and secondary UPJO were 74% and 77% respectively. The grade of obstruction had no impact on results. The median time to the nine failures was 3 months, and no failure occurred more than 6 months after the endopyelotomy. In 75% of the failures with no crossing vessel, redo retrograde Acucise endopyelotomy was successful. CONCLUSION: Retrograde Acucise endopyelotomy is an efficient long-term treatment of UPJO with low morbidity. This technique is a reasonable choice for first-line treatment of UPJO.

[Role of flexible mini-ureteroscopes in diseases of the upper urinary tract]. / Rôle des mini-urétéroscopes flexibles dans la pathologie du haut appareil urinaire.

INTRODUCTION: The management of upper urinary tract disease has been improved by miniaturization of endoscopes. Our objective was to assess the value of flexible mini-ureteroscopes for the diagnosis and treatment of upper urinary tract lesions. PATIENTS AND METHODS: 33 consecutive patients (mean age: 49 +/- 16 years; 23 men) underwent first-line flexible ureteroscopy for upper urinary tract disease, consisting of: stones: 21, filling defect: 6, stenosis: 3, haematuria: 2, positive cytology: 1 and situated in the kidney + renal pelvis: 14 or ureter: 19. The 21 stones were situated in: the calyx: 5, renal pelvis: 1, lumbar ureter: 8, iliac ureter: 3, pelvic ureter: 4. Their mean dimensions were 9.7 +/- 4 x 5.3 +/- 2.3 mm. Previous treatment had failed for 13 stones. There 7.5 F flexible ureteroscopes of various brands were used. RESULTS: All patients were operated under general anaesthesia. Antegrade ureteroscopy was performed in 2 patients. Advancement of the ureteroscope was considered to be difficult in 5 cases, including the 2 antegrade cases. 13 stones were fragmented by hydroelectric waves. The mean duration of ureteroscopy was 40 +/- 15 min. The mean hospital stay was 2.8 +/- 1 days. There was no intraoperative or perioperative morbidity. Ureteroscopy was considered to be successful in 27 cases (82%) and a failure in 6 cases: fragmentation: 3 and progression: 3. Fifteen patients were reviewed after more than one month (3 +/- 2 months) with no morbidity. CONCLUSION: Ureteroscopy with flexible mini-ureteroscopes is an effective, reproducible and minimally traumatic diagnostic and therapeutic technique. It is particularly useful for lesions situated above the iliac vessels and is indicated for diagnostic assessment and stones, but also upper tract malformations and strictures.

Effect of digital rectal examination on serum complexed and free prostate-specific antigen and percentage of free prostate-specific antigen.

OBJECTIVES: To evaluate the effects of digital rectal examination (DRE) on serum total, calculated complexed, and free prostate-specific antigen (PSA) and the free/total PSA ratio and factors affecting variations of PSA. METHODS: Serum total and free PSA and the percent free PSA ratio were determined in 91 urologically referred men (mean age 64 +/- 9 years) before and 30 minutes after DRE, with the Hybritech Tandem-R assay. Complexed PSA was calculated as the difference between total and free PSA. DRE effects on PSA were analyzed comparing pre-DRE and post-DRE values and by calculating the difference between pre-DRE and post-DRE PSA and the post/pre-DRE geometric ratio as a coefficient of variation. RESULTS: Thirty minutes after DRE, the increase in total, calculated complexed, and free PSA and the percent free PSA ratio was statistically significant. The difference between post-DRE and pre-DRE values of serum total, calculated complexed, and free PSA and percent free PSA was +0.9, +0.3, and +0.6 ng/mL and + 10%, respectively. The post/pre-DRE ratio of serum total, calculated complexed, and free PSA and percent free PSA was x1.5, x1.22, and x2.5 and x1.7, respectively. Patient age, DRE findings, prostate volume, prostate histologic features, and the initial value of total PSA had no statistically significant effect on the change of percent free PSA after DRE. The initial percent free PSA had a statistically significant effect on the change of percent free PSA after DRE. The values of calculated complexed PSA before and after DRE were significantly higher in patients with a prostate volume greater than 40 cc, prostate cancer on biopsy, and an initial free/total PSA ratio greater than 18%. CONCLUSIONS: In this study, DRE significantly increased total, calculated complexed, and free PSA and percent free PSA. The increase of PSA immediately after DRE was mainly due to the increase of free PSA. The change of percent free PSA after DRE depended on the initial percentage of free PSA. Complexed PSA seems less sensitive to DRE, and its changes after DRE were clinically modest. Free PSA measurement should be done before DRE and percent free PSA should be used only when the venipuncture is done before the DRE.

[Retroperitoneal non-secreting paraganglioma]. / Paragangliome non sécrétant rétropéritonéal.

Paraganglioma is a rare tumor arising from indifferentiated cells of the primitive neural crest. These tumors are most commonly found in the adrenal gland but other localisations are possible. We described a 60-year-old men with a right retro-peritoneal mass discovered on ultrasound examination. This tumor had an heterogeneous appearance on i.v. contrast injected CT (computed tomography) and MR (magnetic resonance) images. Plasma and urinary catecholamines were normal. This tumor was surgically removed. Immunohistochemical analyses revealed that the tumor cells were strongly positive for neurone specific enolase and chromogranin A. Histopathologic examination diagnosed a non secreting paraganglioma in the right retroperitoneum. After surgery, the patient remained asymptomatic without treatment.

[Acucise endoureterotomy for distal ureteral stenosis in a renal transplant patient]. / Endourétérotomie Acucise pour sténose de l'uretère distal chez un transplanté rénal.

The treatment of ureteric strictures in renal transplantation used to be surgical, but has recently benefited from progress in endourology. The authors report the case of a renal transplant recipient who developed late stricture of the ureterovesical reimplantation of the transplant. After percutaneous nephrostomy, which restored good renal function, retrograde endoureterotomy was performed using an Acucise ureterotome balloon, followed by ureteric modelling on a 7F double J stent for 2 months. With a follow-up of 18 months, renal function was normal and ultrasonography showed residual hypotonia of the transplant cavities and no vesicorenal reflux was detected by retrograde voiding cystourethrography. Acucise retrograde endoureterotomy can constitute a simple endourological treatment for late ureteric strictures in renal transplantation.

[An incrusted ureteral stent: use of a Lithoclast. Apropos of a case]. / Sonde urétérale incrustée: utilisation du Lithoclast. A propos d'un cas.

Ureteric stents can be complicated by incrustations, sometimes making it impossible to withdraw or replace the stent over a guide. In this exceptional indication, we report a case in which the use of the Swiss-Lithoclast pneumatic lithotriptor allowed withdrawal of an incrusted double J stent. There was no morbidity related to the use of the Lithoclast. Among the various techniques available for removal of these incrusted double J stents, endoprosthetic lithotripsy appears to be the most effective and the least invasive, in selected cases.

Prognostic significance of incidental renal cell carcinoma.

From 1980 to 1991, 236 patients with renal cell carcinoma were treated in our department. We studied the characteristics and the prognostic significance of 74 patients with incidental renal cancer in comparison with those with symptomatic tumors. The mean age of the patients was 59.8 years and the sex ratio 2 males/1 female. The incidence of incidental tumors increased from 14% in 1980 to 48% in 1991. Incidental tumors were discovered mainly during examination for cardiovascular diseases (26%), hepatobiliary diseases (22%) and general health examination (23%). Local tumoral stage and histologic grade were significantly lower for the incidental tumors than for symptomatic ones (p = 0.002 and p = 0.001). In the same way, the rates of the patients with metastases or nodal involvement were lower for those with incidental tumors than for those with symptomatic tumors (p = 0.008 and p = 0.001). The mean tumoral size was 5.7 +/- 3 cm for incidental tumors and 7.6 +/- 3.5 cm for symptomatic tumors (p = 0.0001). The survival was significantly different according to the circumstances of detection of the tumors (p < 0.001); the 5- and 10-year actuarial survival rates was 85% for the patients with incidental tumors and respectively 61 and 44% for the patients with symptomatic tumors. The multivariate analysis by Cox proportional hazard model showed three important and independent prognostic factors: the presence of metastases (relative risk (RR): 6.7), nodal involvement (RR: 4.6) and symptomatic tumors (RR: 1.7). The patients with incidental tumors had a better prognosis than those with symptomatic tumors because of lower tumoral size and local stage. The early diagnosis of renal cell carcinoma improved the prognosis of the patients.

[Treatment of splenic trauma. Apropos of a series of 52 cases]. / Traitement des traumatismes spléniques. A propos d'une série de 52 cas.

Our serial is composed of 52 cases analysed after a backward upper two years. Because the happening of flashing infections sometimes many years after splenectomy, the therapic gesture must be prioritally leaded by splenic conservation, possible in all cases except the lesions of type 4 (spleen burst or pedicule extract): the perisplenic resorbable prothesis is a precious contribution. The analysis of results confirms the reliability of splenic conservation (47%) with 91% excellent results.
