Endoscopic intact removal of medium-size- or multiple bladder stones with the use of transvesical laparoendoscopic single-site surgery.

OBJECTIVES: To determine the feasibility and safety of performing transvesical laparoendoscopic single-site surgery (T-LESS) in patients with medium-size, hard stones or multiple stones with high burden. METHODS: In this case series study, 12 patients (11 males and one female) with a mean age of 66.8 years were operated on from February 2016 to May 2017 due to bladder calculi, using the T-LESS approach with a single-port device (Tri-Port + , Olympus, Germany). Indications for this procedure were hard, medium-size, solitary stones after previous unsuccessful endoscopic lithotripsy or the presence of multiple high-burden stones. In two patients, additional procedures (diverticulectomy or a ureterocele incision) were performed simultaneously. RESULTS: All stones were removed intact. No serious complications were observed. The mean operative time was 46 min and the postoperative hospital stay was 22 h. The mean diameter of the largest stone and the mean stone volume of each case were 24 mm and 11 cm3, respectively. At the mean follow-up time of 15 months, there was significant improvement of the symptoms. CONCLUSIONS: The T-LESS technique is an efficient, safe and minimally invasive procedure for intact bladder stone removal in selected patients. The method avoids the risk of urethral injury. Nevertheless, further investigation is needed to assess the wider applicability of the procedure.

Laparoscopic sacrocolpopexy for neovaginal prolapse in a patient after male-to-female sex reassignment surgery.

INTRODUCTION: Male / female sex reassignment surgery is performed on transsexuals, and includes removal of the male external genitalia, and creation of the neovagina from the skin of the penis, usually allowing sexual intercourse (1, 2). The incidence of the prolapse of the neovagina is not known; however, such complication is observed relatively rarely (3, 4). the long-term outcomes of prolapse treatment in transsexual patients are not available in the literature. The purpose of this study was to demonstrate laparoscopic sacrocolpopexy to repair a neovagina prolapse in a patient after male-to-female sex reassignment surgery. MATERIALS AND METHODS: In september 2013, a laparoscopic repair was performed on a 44-year-old woman who presented a neovaginal prolapse of pelvic organ prolapse quantification (pop-q) stage iii, twenty one years after sex reassignment surgery. This condition caused painful or even indisposed intercourse. in may 2013, the patient underwent unsuccessful vaginal treatment with the suturing device. Before the initial surgery, the patient was examined with cystoscopy, urodynamics and microbiology; no pathologies were found. laparoscopic repair of the neovaginal prolapse followed the principles described previously in the natural female (5). In the supine lithotomy position, a standard multiport laparoscopic sacrocolpopexy was performed with the use of the polypropylene mesh (Artisyn® y-shaped mesh, ethicon, inc somerville, nj.) and coated polyglactin sutures. The following steps were applied: exposure of the anterior and posterior neovaginal walls; suturing the bifurcated end of the mesh to the neovagina; longitudinal incision of the parietal peritoneum and creation of a tunnel for the mesh; fixation of the proximal end of the mesh to the promontorium; and closure of the parietal peritoneum over the mesh that was placed retroperitoneally. The draining tube was left for 24 hours. RESULTS: The operation was completed successfully, with no blood loss or complications. The operative time was 115 minutes. The patient was discharged on the 2nd postoperative day. In a four-year follow-up, the patient presented significant improvement of symptoms, a small prolapse of approximate pop-q stage i, and declared performing satisfying intercourse. CONCLUSIONS: Laparoscopic sacrocolpopexy with the use of a polypropylene mesh to repair a neovaginal prolapse in transsexuals seems to be a valuable alternative to other procedures. Further observations and evaluation of a greater number of patients will be necessary to assess the actual value of the method.

[Transvesical laparoendoscopic single-site approach for repair of urinary tract injuries after vaginal or pelvic surgery]. / Przezpecherzowa laparoendoskopowa naprawa wybranych uszkodzen ukladu moczowego po operacjach pochwowych lub miednicznych.

OBJECTIVES: To present a one-center clinical experience of using the transvesical laparoendoscopic single-site surgery (T-LESS) to repair selected urinary tract injuries after vaginal or pelvic surgery. MATERIAL AND METHODS: From November 2009 to August 2013, 22 women underwent the treatment with the use of the T-LESS technique to repair various complications after gynecologic or uro-gynecologic surgery. Thirteen patients were operated on for iatrogenic foreign bodies, 8 patients underwent a vesicovaginal fistula repair and 1 woman a ureteral reimplantation due to ureterovaginal fistula. In all cases, the TriPort system was established intravesically and standard laparoscopic instruments were used. When needed, bladder and vaginal wall defects were closed with barbed V-Loc suture. RESULTS: The treatment was successful in all patients. In one case the procedure was converted to open approach. No blood loss or complications were observed. Mean operative time was 78 min. and mean hospitalization time was 3.6 days. The postoperative pain was 0.7 (Visual Analogue Scale) on postoperative day 1. During the average follow-up of 78 months no adverse events related to the method except for one small asymptomatic mesh erosion were noticed. CONCLUSIONS: The T- LESS approach for repair of selected urinary tract injuries after vaginal or pelvic surgery is a feasible, efficient and safe procedure. It offers excellent visualization inside the bladder, availability of intracorporeal watertight suturing and minimal postoperative pain. Nevertheless, substantial development of the instruments and further investigations are necessary to assess the usefulness of this technique.

Transvesical laparoendoscopic single site surgery to remove surgical materials penetrating the bladder: initial clinical experience in 9 female patients.

PURPOSE: The optimal approach for removing surgical materials that have penetrated the bladder is still debatable. We reviewed our initial experience with transvesical (percutaneous intraluminal access) laparoendoscopic single site surgery to treat such complications. We determined the safety, efficacy and morbidity of the procedure. MATERIALS AND METHODS: In this case series study 9 women 24 to 63 years old were operated on from November 2009 to July 2012 due to bladder tape/mesh or surgical suture extrusion using the transvesical (percutaneous intraluminal access) laparoendoscopic single site surgery approach. We used the TriPort™ or TriPort+ single site access system, and a combination of straight and articulating or only standard laparoscopic instruments. A running V-Loc™ suture was placed as needed. In all cases followup included urine tests, abdominal ultrasound and cystoscopy. RESULTS: Mean operative time was 59 minutes (range 35 to 105). Median postoperative hospital stay was 2.4 days. No blood loss or complications were observed except 1 conversion to open surgery because of a perivesical abscess. No extra port was added. No adverse events related to the method were observed during the mean 19-month followup. In 1 patient mesh extrusion recurred after 12 months of followup. CONCLUSIONS: We consider this technique to be an efficient, safe procedure and a valuable minimally invasive treatment option for foreign body removal from the bladder. However, further observations are needed to prove the validity of the method.

Not as black as it is painted? The impact of the first wave of COVID-19 pandemic on surgical treatment of urological cancer patients in Poland - a cross-country experience.

Introduction: In the majority of Western European countries, the coronavirus disease (COVID-19) pandemic has led to a dramatic reduction in urooncological surgeries. Our objective was to evaluate the impact of the pandemic on volume and patterns of urooncological surgery in Poland. Material and methods: This is a retrospective analysis of 10 urologic centres in Poland. Data regarding major oncological procedures performed after the COVID-19 pandemic outbreak (March 15, 2020 - May 31, 2020) were evaluated and compared with data from the respective period in 2019. Results: Between March 15, 2020 and May 31, 2020, a total of 968 oncological procedures were performed in participating centres. When compared to the respective period in 2019 (1063 procedures) the overall number of surgeries declined by 8.9%. The reduction was observed for transurethral resection of bladder tumour (TURBT) (20.1%) and partial nephrectomies (PN) (16.5%). Surgical activity considering radical nephrectomy (RN), nephroureterectomy (NU), and radical prostatectomy (RP) remained relatively unchanged, whereas radical cystectomy (RC) burden showed a significant increase (90.9%). Characteristics of patients treated with TURBT, RC, NU, PN, and RN did not differ significantly between the compared periods, whereas RP in the COVID-19 period was performed more frequently in patients with a higher grade group (p = 0.028) and positive digital rectal examination (p = 0.007). Conclusions: Surgical activity for urological cancers in Poland has been maintained during the first wave of the COVID-19 pandemic. The Polish strategy in the initial period of the COVID-19 crisis mirrors the scenario of hard initial lockdown followed by adaptive lockdown, during which oncological care remained undisrupted and did not require particular priority triage.

Binding indocyanine green to human serum albumin potentially enhances the detection of sentinel lymph nodes. An initial step for facilitating the detection of first-station nodes in penile and other urological cancers.

Introduction: Surgical oncology strives to remove the primary cancer tumor together with its local lymphatic tissue. One of the techniques improving the staging of lymph nodes is sentinel node biopsy. The most common agent used in SNB is indocyanine green (ICG). Indocyanine green is characterized by its high affinity for human serum albumin (HSA). In practice, the visualization of the sentinel node is enhanced by attaching a relatively large carrier to the ICG molecule. The aim of this study was to investigate whether the covalent linking of ICG to a nanocolloid would extend the time of detection of the dye as it binds to HSA, assessed by fluorescence measurements in vitro. Material and methods: The influence of the molar concentration of ICG on its ability to form a complex with HSA was investigated. The dye luminescence was measured, with an increasing amount of dye in the presence of a constant concentration of HSA. The stability of the ICG:HSA complex was also investigated. Results: The binding of ICG and human protein in a solution ratio of 3 : 1 made it possible to detect the ICG luminescence with better and prolonged visibility. In the case of the two lowest ratios, complex formation was not observed. The use of ICG bound to a nanocolloid based on human serum albumin increases the luminescence of the HSA : ICG complex up to 98%. Conclusions: Properly selected proportions of human albumin protein and ICH allowed higher and longer luminescence to be achieved. Nevertheless, further studies are necessary to establish the optimal concentration ratio.

The View Outside of the Box: Reporting Outcomes Following Radical Cystectomy Using Pentafecta From a Multicenter Retrospective Analysis.

We aimed at characterization of the patients undergoing radical cystectomy (RC) using the prognostic model (a modified pentafecta). In the multicenter retrospective study, we enrolled 304 patients with bladder cancer (pTis-4N0-2M0) who underwent RC between 2015 and 2020 in experienced centers. The definition of the pentafecta was as follows: no Clavien-Dindo grade III-V complications at 90 days and no long-term complications related to urinary diversion <12 months, negative surgical margins, ≥10 lymph nodes (LNs) resected, and no recurrence ≤12 months. RC-pentafecta achievement rate was 22% (n = 67), varying from 47% to 88% attainment rate for different pentafecta components, and was the lowest for sufficient LN yield. Both 12-month recurrence-free survival (RFS) and cancer-specific mortality were compromised in pentafecta failers compared with achievers (57.8% vs. 100% and 33.8% vs. 1.5%, respectively). The following were identified as crucial predictors of RC pentafecta achievement: modality of the surgery, type of urinary diversion, histological type of bladder cancer, advanced staging, and elevated preoperative serum creatinine. In conclusion, we found that the pentafecta achievement rate was low even in high-volume centers in patients undergoing cystectomy. The complexity of the procedure directly influenced the attainment rate, which in turn led to an increase in cancer-specific mortality rate among the pentafecta failers.

Initial Experience of Clinical Use of [99mTc]Tc-PSMA-T4 in Patients with Prostate Cancer. A Pilot Study.

Numerous different molecules of prostate-specific membrane antigen (PSMA) ligands are used to detect prostate cancer (PCa); most approaches utilize gallium PET and a few reports describe the role of SPECT/CT. [99mTc]Tc-PSMA-T4 is a new radiopharmaceutical designed for the diagnosis of patients with PCa. We conducted a single site, prospective, preliminary case series study that included 31 patients with PCa; all had undergone clinical, biochemical or imaging examination and exhibited clear or suspicious active disease or clinical/biochemical recurrence of PCa. Whole-body (WB) SPECT/CT after i.v. administration of [99mTc]Tc-PSMA-T4 was utilized; acquisition images were obtained at three time points. The clinical value of the images was assessed in regard to the evaluation of tumor extent in patients with confirmed PC that qualified for initial therapy and the evaluation of tumor recurrence; both provided encouraging results. The late acquisition of WB-SPECT resulted in better lesions delineation. The results of the analysis of the sensitivity/specificity were: 92%/100% in cases of primary cancer, 83%/100% in terms of pelvic lymph nodes disease, 100%/95% in other lymph nodes and soft tissue involvement, respectively, and bone mets were both 100%. An oncotropic SPECT [99mTc]Tc-PSMA-T4 can help in selecting a rational therapeutic strategy for a patient with an initial diagnosis of PCa by assessing the extent of cancer and also after complex radical or palliative therapy in case of biochemical recurrence for re-staging.

Changing patterns of urologic emergency visits and admissions during the COVID-19 pandemic: a retrospective, multicenter, nationwide study.

INTRODUCTION: We aimed to examine the change in the number and severity of visits to the emergency departments (EDs) and subsequent admissions for urgent urologic conditions in the early stage of the coronavirus disease 2019 (COVID-19) pandemic in Poland. MATERIAL AND METHODS: We evaluated data from 13 urologic centers in Poland and compared the number of visits to the EDs and subsequent admissions before and after the advent of COVID-19 in 2020, and before and after the escalating national restrictions. Furthermore, data on types of urologic complaints, crucial laboratory parameters, and post-admission procedures were analyzed. RESULTS: In total 1,696 and 2,187 urologic visits (22.45% decrease) and 387 and 439 urologic urgent admissions (11.85% decrease) were reported in given periods in 2020 and 2019, respectively. The year-over-year difference in daily mean visits was clear (36.1 vs. 46.5; p < 0.001). Declines were seen in all complaints but device malfunction. In 2020 daily mean visits and admissions decreased from 40.9 and 9.6 before lockdowns to 30.9 (p < 0.001) and 6.9 (p = 0.001) after severe restrictions, respectively. There was a trend towards more negative laboratory parameter profiles in 2020, with patients who visited the EDs after severe restrictions having twice as high median levels of C-reactive protein (15.39 vs. 7.84, p = 0.03). CONCLUSIONS: The observed declines in ED visits and admissions were apparent with the significant effect of national lockdowns. Our results indicate that some of the patients requiring urgent medical help did not appear at the ED or came later than they would have done before the pandemic, presenting with more severe complaints.

Prediction of the risk of surgical complications in patients undergoing monopolar transurethral resection of bladder tumour - a prospective multicentre observational study.

INTRODUCTION: The aim of the study was to identify predictors of surgical complications of transurethral resection of bladder tumour (TURBT). MATERIAL AND METHODS: We prospectively recruited 983 consecutive patients undergoing TURBT within 7 months in six academic institutions. All patients were followed up from the surgery up to 30 days postoperatively with at least one telephone contact at the end of the observation. The primary study endpoint was any intra- or postoperative surgical complication. For the identification of predictors of complications, univariate and multivariate logistic regression models were used. Trial registration: ClinicalTrials.gov (NCT03029663). Registered 24 January 2017. RESULTS: Surgical complications were noticed in 228 (23.2%) patients, including 83 (8.4%) patients with more than one complication and 33 cases of Clavien-Dindo grade 3 complications (3.3%). The most common in-hospital complications were bleeding (n = 139, 14.1%) and bladder perforation (n = 46, 4.7%). In a multivariate analysis, nicotine use, high ASA score, and the presence of high-grade tumour were the most significant predictors of high-grade complications. The stage of the disease was the strongest predictor of bleeding, while the presence of muscle in the specimen and resident surgeon were the strongest predictors for bladder perforation. CONCLUSIONS: TURBT poses a significant risk of surgical complications, the majority of which are of low grade.

Metabolomic Heterogeneity of Urogenital Tract Cancers Analyzed by Complementary Chromatographic Techniques Coupled with Mass Spectrometry.

BACKGROUND: In regard to urogenital tract cancer studies, an estimated 340,650 new cases and 58,360 deaths from genital system cancer and about 141,140 new cases and 29330 deaths from urinary system were projected to occur in the United States in 2012. The main drawbacks of currently available diagnostic tests constitute the low specificity, costliness and quite high invasiveness. OBJECTIVE: The main goal of this pilot study was to determine and compare urine metabolic fingerprints in urogenital tract cancer patients and healthy controls. METHOD: A comparative analysis of the metabolic profile of urine from 30 patients with cancer of the genitourinary system (bladder (n=10), kidney (n=10) and prostate (n=10)) and 30 healthy volunteers as a control group was provided by LC-TOF/MS and GCQqQ/ MS. The data analysis was performed by the use of U-Mann Whitney test or Student's t-test, principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis (OPLS-DA). RESULTS: As a result, 33, 43, and 22 compounds were identified as statistically significant in bladder, prostate and kidney cancer, respectively, compared to healthy groups. CONCLUSION: Diverse compounds such as purine, sugars, amino acids, nucleosides, organic acids which play a role in purine metabolism, in tricarboxylic acid cycle, in amino acid metabolism or in gut microbiota metabolism were identified. Only two metabolites namely glucocaffeic acid and lactic acid were found to be in common in studied three types of cancer.

Single-session Transvesical Laparoendoscopic 1-Port Removal of 2 Bladder Diverticula in a Female Patient.

BACKGROUND: Bladder diverticula are usually encountered in males, and they are a rarity in women, especially in the absence of obstruction. Open surgery, as well as laparoscopic or robotic, or single-port surgery have been applied successfully to remove bladder diverticula.1-3 To the best of our knowledge, no single-port diverticulectomies have been performed in women. OBJECTIVE: To present the case of using the transvesical laparoendoscopic single-port surgery (T-LESS) for excision of 2 bladder diverticula in a woman. MATERIALS: In August 2016, we carried out the T-LESS access on a 67-year old woman to remove 2 symptomatic bladder diverticula in 1 session. The patient was placed in the lithotomy position and was under general anesthesia. The procedure was performed transvesically (percutaneous intraluminal approach) with a single-port device (Tri-Port+) via a 1.5-cm incision made 3 cm above the pubic symphysis. Standard 10-mm optic and straight laparoscopic instruments were used. The diverticula were dissected and removed from the bladder with a combination of standard laparoscopic and endoscopic instruments introduced through the TriPort+ or the urethra. The bladder wall openings were closed by running absorbable 2/0 polyglactin sutures. An 18F Foley catheter was left in place for 6 days. RESULTS: The operation lasted 120 minutes. Blood loss was minimal, and no complications were observed. The postoperative period was uneventful. The patient was discharged within 19 hours of surgery. During a 9-month follow-up, the patient reported the significant improvement in the severity of symptoms. Laboratory examination results were all within the normal range. CONCLUSION: The T-LESS procedure can be considered as a valuable option for diverticulectomies in female patients because of its minimal invasiveness, short hospital stay, and fast recovery time.

Laparoscopic nephroureterectomy with transvesical single-port distal ureter and bladder cuff dissection: points of technique and initial surgical outcomes with five patients.

Although a variety of techniques have been used to manage the distal ureter during laparoscopic radical nephroureterectomy (LNU), a consensus has not yet been established. Recently, some authors have used a single-port transvesical approach to excise the distal ureter and bladder cuff following LNU. The aim of the study was to present our initial experience in "en bloc" dissection of the distal ureter and bladder cuff during LNU, using a transvesical single-port approach (T-LESS) and standard laparoscopic instruments. From April to October 2012, 5 patients aged 45 to 73 years with upper urinary tract urothelial tumors were subjected to LNU/T-LESS. After a standard LNU was performed, a TriPort+(®) device was introduced into the bladder and the pneumovesicum was established. A bladder cuff with a distal ureter was dissected and put in the paravesical tissue. The bladder wall defect was closed with the V-loc(®) 3/0 suture. The LNU was then completed in the flank position. All procedures were completed successfully. No significant blood loss or complications were observed. The mean operative time was 250 min (range: 200-370) for a total procedure and 59 min (range: 42-80) for the T-LESS stage. The postoperative hospital stay was 5.2 days (range: 4-9). Pathologic examination revealed no positive margin in any of the cases. The LNU/T-LESS approach is an efficient and safe procedure. A well-visualized dissection of the distal ureter, closing the defect of the bladder, the use of standard laparoscopic instruments and a good cosmesis are advantages of the method.

Suprapubic transvesical laparoendoscopic single-port bladder diverticulectomy: points of technique with medium-term surgical outcomes.

BACKGROUND AND PURPOSE: Various minimally invasive techniques have been developed for bladder diverticulectomy. One of the newest is transvesical laparoendoscopic single-site (T-LESS) surgery. In this article, we present points of technique with initial clinical results after a minimum of 7 months of follow-up. The aim of the study was to assess our first series of patients who underwent T-LESS surgery for transvesical excision of symptomatic bladder diverticula. PATIENTS AND METHODS: From March 2011 to February 2012, we successfully operated on five men aged 61 to 76 years (mean 66 years) for symptomatic (infections, residual of urine, neoplasm) bladder diverticula, with the use of the T-LESS approach. The procedures were performed using single-port TriPort+, standard laparoscopic instruments, and V-loc suture. All patients underwent follow-up of 6 weeks after surgery and every 3 months thereafter. The follow-up included urine tests, ultrasonography, and cystoscopy when needed. RESULTS: The average operative time was 122 minutes (range 80-175 min), and the blood loss was minimal. Patients were discharged on the third (range 2-4 day) postoperative day with no intra- or postoperative complications. The average 14-month follow-up (range 7-19 mos) confirmed good operative results in all cases. An insignificant small recurrent diverticulum was observed in one patient. The patients did not need transurethral resection of the prostate or reoperation. CONCLUSIONS: We consider this technique to be a feasible and safe procedure, and a valuable treatment option for bladder diverticulectomy.

Laparoendoscopic single-port transvesical diverticulectomy: preliminary clinical experience.

PURPOSE: We present our single-center experience with three patients who were undergoing laparoendoscopic single-site (LESS) diverticulectomy through a single-port device introduced directly into the bladder. PATIENTS AND METHODS: During March and April 2011, we operated on three men aged 62 to 76 years (mean 67 y) for symptomatic bladder diverticula using a standard lithotomy position and general anesthesia. The procedure was performed transvesically (percutaneous intraluminal approach) with a single-port device (four-channel) via a 1.5-cm incision made 2 cm above the pubic symphysis. Standard 10-mm optic and rigid laparoscopic instruments were used. The defect of the bladder wall was closed with an absorbable 3/0 running V-Loc suture. An 18F Foley catheter was left for 4 to 7 days. RESULTS: The average operative time was 128 minutes (range 80-175 min). The blood loss was minimal. Patients were discharged on the third postoperative day with no intra-, nor postoperative complications. The 3-month follow-up confirmed good operative results in all cases. CONCLUSION: We consider laparoendoscopic single-port transvesical excision of bladder diverticulum as a feasible and safe procedure and a valuable treatment option for bladder diverticulectomy.

Suprapubic transvesical laparoendoscopic single-site surgery for vesicovaginal fistula repair: a case report.

Some minimally invasive techniques have been introduced to decrease morbidity related to standard laparoscopic procedures. One such approach is laparoendoscopic single-site surgery (LESS), which can also be applied for transvesical surgery. The aim of the study was to present our initial clinical experience of using this technique for transvesical vesicovaginal fistula (VVF) repair. In August 2011, we carried out the LESS repair of a 3-mm in diameter vesicovaginal fistula on a 72-year-old woman, who failed the conservative treatment with Foley placement. The procedure was performed transvesically (percutaneous intraluminal approach) with a single-port device (4-channel, TriPort+, Olympus Winter&IBE GMBH) via a 1.5-cm incision made 2 cm above the pubic symphysis. A standard 10-mm optic and straight laparoscopic instruments were used. The fistulous tract was dissected and partially excised. The bladder and vaginal wall defects were closed in two layers with running absorbable V-Loc (Covidien, Norwalk, CT, USA) suture. Ureteral catheters were left for 5 days and the Foley catheter for 14 days. The operative time was 170 min. The blood loss was minimal. No complications were observed. The postoperative period was uneventful. During a 6-month follow-up the patient reported no involuntary discharge of urine into the vagina. Diagnostic scans revealed no presence of VVF and laboratory examination results were all within the normal range. Although substantial development of the instruments and skills is needed, the transvesical LESS vesicovaginal fistula repair appeared to be feasible and safe. Nevertheless, further experience and observations are necessary.
