Is a Mesh Really a Mess: A Self-Tailored Polypropylene Mesh as a Retropubic Tension-Free Vaginal Tape Under Local Anesthesia in a Tertiary Healthcare Center Experience in India.

Objective The primary objective of this study was to evaluate the feasibility of performing retropubic mid-urethral transvaginal tape (TVT) with self-tailored ordinary polypropylene mesh (STOM) under sedation and local anesthesia in female patients with stress urinary incontinence (SUI). The second objective was to evaluate perioperative and immediate postoperative complications, success rates, and cost-effectivity. Materials and methods Forty-two subjects treated for stress urinary incontinence using STOM under local anesthesia were reviewed. Pre- and postoperative evaluation included assessment of valid questionnaires such as the urogenital distress inventory (UDI) and medical, epidemiologic, and social aspects of aging incontinence questionnaire (MESA), uroflowmetry in all cases, and urodynamics in some instances. Success rates and complications were compared with published studies. Results The mean operating time was 27 mins, and the median visual analog scale (VAS) score at 12 hours was three. Postoperative MESA and UDI scores had significant improvement. The mean hospital stay was 18 hours. Mean preoperative and postoperative Q max had no significant difference. With a mean follow-up of 27.32±3.29 months, the cure was seen in 38 patients (90.4%), improvement in three patients (0.07%), and failure in one patient (0.02%). Mesh-related complications (extrusion) occurred in one patient. The sling cost was reduced from approximately $500 (Gynecare TVT sling; Ethicon Inc., Somerville, NJ, USA) to $12.44 (Ethicon 15 x 7.6 cm Prolene (polypropylene mesh); Ethicon Inc., Somerville, NJ, USA) in our study. Conclusion Performing TVT with STOM under sedation and local anesthesia as a daycare procedure was feasible and cost-effective, has a high success rate, and was associated with minimal complications. It should be considered in developing countries with vast patient burdens, such as India.

Sarcomatoid Urothelial Carcinoma of the Urinary Bladder With Chondrosarcomatous and Concurrent Divergent Squamous Cell Carcinoma Differentiation- A Rare Entity.

We present an extremely rare case where the sarcomatoid urothelial carcinoma of the urinary bladder was present with chondrosarcomatous and squamous cell differentiation. A 74-year-old male smoker presented with intermittent hematuria with the passage of clots. On imaging, an irregular polypoidal lesion was diagnosed near the right vesicoureteric junction, and transurethral resection of the bladder tumor was performed. Histopathological examination showed sarcomatoid urothelial carcinoma with chondrosarcoma and squamous cell differentiation. He refused the surgical treatment of radical cystectomy and underwent Gemcitabine and Cisplatin chemotherapy. He died nine months after the diagnosis. Sarcomatoid urothelial carcinoma is a high-grade biphasic neoplasm with malignant epithelial and mesenchymal components. Its association with squamous cell carcinoma is infrequent. It is very aggressive, and there is no standard treatment for this disease. The radical surgical option appears to be the main form of treatment. It is scarce with a grave prognosis.

Does successful urethral calibration rule out significant female urethral stenosis? confronting the confounder- an outcome analysis of successfully treated female urethral strictures

ABSTRACT Objective: The diagnosis and treatment of female urethral stricture disease (FUSD) are practiced variably due to the scarcity of data on evaluation, variable definitions, and lack of long-term surgical outcomes. FUSD is difficult to rule out solely on the basis of a successful calibration with 14F catheter. In this study, we have tried to characterize the variable clinical presentation of FUSD, the diagnostic utility of calibration, videourodynamic study(VUDS), and urethroscopy in planning surgical management. Materials and Methods: A retrospective review of records of 16 patients who underwent surgical management of FUSD was analyzed. The clinical history, examination findings, and the results of all the investigations (including uroflowmetry, VUDS findings, urethroscopy) they underwent, the procedures they had undergone, and the follow-up data were studied. Results: A total of 16 patients underwent surgical management of FUSD. 13 out of 16 patients had successful calibration with 14F catheter on the initial presentation. These 13 patients on VUDS demonstrated significant BOO and had variable stigmata of stricture on urethroscopy. The mean IPSS, flow rate, and PVR at presentation and after urethroplasty were 23.88±4.95, 7.72±4.25mL/s, 117.06±74.46mL and 3.50±3.44, 22.34±4.80mL/s, and 12.50±8.50mL, respectively. (p <0.05). The mean flow rate after endo dilation(17F) (n=12) was 11.4±2.5mL/s while after urethroplasty improved to 20.30±4.19mL/s and was statistically significant(p <0.05). Conclusions: An adept correlation between clinical assessment, urethroscopy findings, and VUDS is key in objectively identifying FUSD and planning surgical management. A good caliber of the urethra is not sufficient enough to rule out a significant obstruction due to FUSD. Early urethroplasty provides significantly better outcomes in patients who have failed dilation as a treatment.

Effect of Structured Educational Program on Practices of Radiation Safety Measures Among Health Care Providers in Urology Operation Theater.

Introduction Endourologists are at increased risk of exposure to radiations. Many studies are available that have studied awareness in doctors in general, but very few studies available regarding any intervention to improve the knowledge of radiation safety measures. We have made an attempt to study the role of an educational intervention to improve the knowledge of our Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER) urology operation theater health care providers (HCPs). Materials and methods Our study was an Interventional study (prospective clinical trial), conducted in the Department of Urology, JIPMER from January 2017 to March 2018. All, that is, 40 operation theater HCPs were given a questionnaire as baseline. The baseline response was compared to the response after the Structured Education Program (SEP) by using the same questionnaire. The knowledge of participants before SEP was compared with the knowledge after SEP using the chi-square test. All statistical analysis was carried out at a 5% level of significance and p-value < 0.05 was considered as significant. Result In our study after SEP, participants use of lead apron has increased from 72.5% to 92.5%, indicating improvement. There is an increase in the use of thyroid shield from 22.5% to 95%. In our study after SEP, knowledge about background radiations improved in participants from 25% to 87.5%. Knowledge about Radiation dose of chest X-ray improved from 22.5% to 52.5%. Knowledge about ALARA (As Low As Reasonably Achievable) improved from 47.5% to 95% after SEP. Knowledge that MRI and USG do not have ionizing radiation improved from 62.5% to 97.5%, and from 75% to 92.5% for MRI and USG, respectively, after SEP. Regarding organ sensitivity, 100% HCPs had given correct answers after SEP as compared to 80 before SEP. Conclusion Our study shows that SEP at regular intervals has made significant improvements in daily practice in operation theater HCPs. SEP has increased the use of radiation protective gears among HCP. Hence we recommend SEP at regular intervals for urology operation theater HCPs for a healthy and safe working environment.

Does Diversion in Poorly Functioning Obstructed Kidneys in Adults Favors Reconstructive Surgeries Over Ablative Procedures? A Prospective Study.

Objective In obstructed poorly functioning kidneys, management depends on the recovery potential of the kidney. Some kidneys have good recovery capability and diversion may unfold the real condition of the kidney. This study evaluated whether pre-operative drainage for six weeks results in improvement of renal function in unilateral obstructed poorly functioning kidney with split renal function (SRF) less than 20%. Methods This was a prospective interventional study conducted between March 2013 and December 2015. All patients between 15 and 65 years, with unilaterally obstructed kidney with SRF ≤20% underwent percutaneous nephrostomy (PCN) drainage for six weeks. Patients having post-drainage SRF of ≥15% and per day urine output from PCN > 400 ml were considered for the reconstructive procedure. Nephrectomy was performed in cases with SRF <15% after considering patient preferences. Results Twelve of 17 patients had improvement in SRF; four had no change while one had a decrease in SRF after drainage. The mean improvement in glomerular filtration rate (GFR) and SRF was 1.4 ml/min and 3%, respectively (P = 0.08). Three out of seven patients with SRF of ≥15% showed an improvement of 5% or more while none of the patients with SRF <15% had such an improvement. Eight patients had final SRF <15% and underwent nephrectomy. Factors such as pre-existing SRF, duration of symptoms, kidney size, transverse pelvic diameter, 24-hour urinary output, and etiology for obstruction were not significant in predicting functional improvement. Conclusion Diversion and decompression of poorly functioning kidneys do not result in a significant functional improvement in obstructed kidneys with SRF <15%.

Outcomes of Transposition of Brachiobasilic Arteriovenous Fistula in Two-Stage Technique: A Single-Centre Experience With Literature Review.

Introduction  Arteriovenous fistulae (AVF) are considered a better option for long-term dialysis access. The distal radiocephalic AVF is the most preferred followed by proximal radiocephalic, brachiocephalic and brachiobasilic AVFs (BBAVF) with basilic vein transposition. In case of failure of AVF at other anatomical locations, BBAVF may improve the outcomes for patients needing dialysis for long term. The two-stage technique of BBAVF has easier dissection and lesser devascularisation risk. The disadvantages are need for two interventions and delay in maturation. Materials and Method It was a retrospective observational study including 42 patients who underwent transposition of BBAVF as two-stage procedure from June 2014 to July 2018. The data recorded were demographic characteristics, such as median age, gender, dialysis status at AVF creation and operative duration. Complications like postoperative limb oedema, bleeding and thrombosis of AVF were recorded. Patency and access outcome of AVF were documented at three-month follow-up. Results  Among 42 patients, 27 (64.3%) were males. The median age was 50 years. Around 14% of patients had minor complications like oedema. Eight (19%) patients needed re-exploration due to bleeding or thrombosis. The early access failure rate that is a failure before discharge was 4.7%. The patency rate at three months was 90.5%, but the primary functional rate was 74%. Conclusion  Transposition of BBAVF as a two-step technique is associated with reasonable patency rate and primary functional rate. The related complications were low, and a good number of fistulae could be saved with timely intervention.

Effect of Ureteral Stent Length and Position of Stent Coil in Bladder on Stent-Related Symptoms and Quality of Life of Patients.

INTRODUCTION: Various standardized questionnaires can evaluate ureteral stent-related symptoms. The present study utilized a validated instrument, Ureteral Stent Symptoms Questionnaire (USSQ), to know the impact of the length of double J stent (DJS) in comparison to ureter length on patients and their quality of living. MATERIALS AND METHOD: This study is a prospective clinical study conducted in the Department of Urology at a tertiary care center in South India. Patients who underwent DJS after endoscopic ureteral lithotripsy were included in the study. On a computerized tomography scan, the ureteral to stent length ratio (USR) was calculated. USSQ scores at the time of DJS removal and two weeks thereafter were recorded. The distal coil of the stent in the bladder was recorded as grade 1 - not crossing the midline and grade 2 - crossing the midline. Different symptom scores were compared between both grades of bladder coil and for USR of all the patients. RESULT: A total of 157 patients were included in the study. Over 46 (29.3%) patients had grade-1 and 111 (70.7%) had grade-2 bladder coil. Totally 93 (59.23%) patients reported pain, while 64 (40.77%) patients had no pain. Grade-2 coil patients had more pain than grade 1 (P=0.01). There was a weak inverse relationship between the USR and urinary symptom (P=0.004), pain symptom (P=0.04), and quality of work (P=0.005). CONCLUSION: Stent length or position of the intravesical stent coil does not appear to affect the quality of life except for the pain. Hence, choosing stent length according to ureteral length seems to have a minimal role in decreasing stent-related morbidity.

Laparoscopic ablative and reconstructive surgeries in genitourinary tuberculosis.

BACKGROUND AND OBJECTIVES: Laparoscopy is the present standard of care for urologic diseases. Laparoscopy in renal tuberculosis (genitourinary tuberculosis) is difficult because of inflammation and fibrosis associated with the disease. We present the outcome of our experience of laparoscopy in genitourinary tuberculosis, both ablative and reconstructive. METHODS: The detailed data of patients with genitourinary tuberculosis who underwent laparoscopic surgeries between January 2011 and September 2012 were reviewed. Indications, type of surgery, duration, blood loss, intraoperative problems, postoperative outcomes, and follow-up details were noted. RESULTS: Overall, 7 laparoscopic procedures were performed: 5 nephrectomies, 1 ureteric reimplantation with psoas hitch, and 1 combined nephrectomy and laparoscopy-assisted Mainz II pouch reconstruction. The mean operative time was 192 minutes for nephrectomy, 210 minutes for ureteric reimplantation, and 480 minutes for nephrectomy with Mainz II pouch reconstruction. There were no conversions to open surgery. The mean amount of blood loss was 70 mL for the nephrectomies, 100 mL for ureteric reimplantation, and 200 mL for nephrectomy with Mainz II pouch reconstruction. In 5 of 6 patients who underwent nephrectomy, there was severe perinephric and peripelvic fibrosis posing difficulty in dissection. However, the renal vessels could be controlled individually. The mean postoperative hospital stay was 3 days for the nephrectomies, 5 days for the ureteric reimplantation, and 10 days for the nephrectomy with Mainz II pouch reconstruction. In all cases the recovery was uneventful. CONCLUSIONS: Laparoscopy, though technically more demanding, is a feasible and safe option for ablative and complex reconstructive procedures in genitourinary tuberculosis. It offers the benefits of minimally invasive surgery. The difficulty with this procedure is mostly because of peripelvic and perinephric fibrosis, whereas the lower ureter and bladder are relatively easier to dissect.

Auto-amputation of penis due to carcinoma: still a threat in the era of modern medicine: report of two cases.

Incidence of penile carcinoma is decreasing worldwide. Nevertheless, the incidence of penile cancer is still significant in various tropical countries, and it often presents in advanced stage. We report two unique cases of penile auto-amputation due to advanced cancer and review relevant literature. Both the patients presented with ulcerative lesion replacing penile base following automatic sloughing of the whole penis and voiding dysfunction. In addition, the first patient had metastatic inguinal lymph nodes. Supra-pubic urinary diversion was the initial management in both the patients. The first patient was treated with combined chemo-radiation, but he succumbed to death following two cycles of chemotherapy. The second patient was successfully treated with total penectomy and perineal urethrostomy. He recovered well but was lost to follow-up.

The role of static magnetic resonance urography in the evaluation of obstructive uropathy.

OBJECTIVE: To assess the diagnostic accuracy of static magnetic resonance urography (MRU) in hydronephrosis and to compare parameters of hydronephrosis in MRU with intravenous urography (IVU). MATERIALS AND METHODS: Sixty-nine patients were included in this study of which 55 patients with a total of 63 hydronephrotic units underwent both IVU and MRU. MRU was performed on a 1.5 T scanner using heavily T2-weighted sequences. The level, grade, and cause of obstruction on each modality were interpreted by 2 radiologists. These were compared with the final diagnosis based on other appropriate modalities including imaging, intraoperative and histopathologic diagnosis. RESULTS: The sensitivity and specificity MRU in detecting hydronephrosis were 95% and 100%, respectively. In determining the level of obstruction, the strength of agreement between IVU and MRU using kappa statistics was κ = 0.66, which corresponds to a good level of agreement. The Spearman correlation coefficient for the grade of hydronephrosis on MRU and IVU was 0.92 (95% confidence interval 0.86-0.95), with a P value of < .0001. The correct diagnosis was made in 89.2% of the cases by IVU and in 93.8% of the cases by MRU. CONCLUSION: Along with a high sensitivity and specificity in detecting the presence, level, and grade of hydronephrosis, MRU without contrast also shows a good agreement with IVU. Static MRU can reliably replace IVU when the latter is contraindicated or technically difficult.

Randomized clinical trial comparing effectiveness of intracorpus spongiosum block versus topical anesthesia for performing visual internal urethrotomy for urethral stricture disease.

OBJECTIVE: To compare the efficacy and safety of intracorpus spongiosum block (ICSB) over topical anesthesia for performing visual internal urethrotomy (VIU) in a randomized clinical trial. METHODS: VIU for urethral stricture can be performed under various types of anesthesia, including topical anesthesia. Although recent studies have shown that ICSB and general anesthesia have comparable efficacy for performing VIU, no studies have compared ICSB with topical anesthesia. Forty consenting patients with single, short, passable anterior urethral stricture were randomized into two groups. Group 1 patients received topical 2% lignocaine jelly and group 2 patients received 1% lignocaine ICSB for undergoing VIU. Pain perception during and after the procedure was assessed by visual analog scale (VAS). The changes in vital parameters during the procedure and procedure-related complications were recorded. Statistical analysis was done using the Mann-Whitney test or t test. RESULTS: The mean±standard deviation VAS scores intraoperatively (2.85±1.34) and at 1-hour postoperatively (1.17±0.96) were significantly lower (P<01) in group 2 patients than the corresponding scores in group 1 (4.9±1.9 and 2.35±1.34 respectively). The intraoperative rise in pulse rate and in blood pressure were significantly greater (P<.05) in group 1 patients (13±5.1/min and 11.3±6.44 mm Hg) than in group 2 (8.05±5.54/min and 6.35±5.86 mm Hg). CONCLUSION: ICSB is safe and more effective than topical anesthesia for providing pain relief during VIU. This should become the local anesthesia technique of choice for performing VIU.

Current concepts in the management of pelvic fracture urethral distraction defects.

OBJECTIVES: Pelvic fracture urethral distraction defect (PFUDD) may be associated with disabling complications, such as recurrent stricture, urinary incontinence, and erectile dysfunction. In this article we review the current concepts in the evaluation and surgical management of PFUDD, including redo urethroplasty. MATERIALS AND METHODS: A PubMed™ search was performed using the keywords "pelvic fracture urethral distraction defect, anastomotic urethroplasty, pelvic fracture urethral stricture, pelvic fracture urethral injuries, and redo-urethroplasty." The search was limited to papers published from 1980 to March 2010 with special focus on those published in the last 15 years. The relevant articles were reviewed with regard to etiology, role of imaging, and the techniques of urethroplasty. RESULTS: Pelvic fracture due to accidents was the most common etiology of PFUDD that usually involved the membranous urethra. Modern cross-sectional imaging, such as sonourethrography and magnetic resonance imaging help assess stricture pathology better, but their precise role in PFUDD management remains undefined. Surgical treatment with perineal anastomotic urethroplasty yields a success rate of more than 90% in most studies. The most important complication of surgical reconstruction is restenosis, occurring in less than 10% cases, most of which can be corrected by a redo anastomotic urethroplasty. The most common complication associated with this condition is erectile dysfunction. Urinary incontinence is a much rarer complication of this surgery in the present day. CONCLUSIONS: Anastomotic urethroplasty remains the cornerstone in the management of PFUDD, even in previously failed repairs. Newer innovations are needed to address the problem of erectile dysfunction associated with this condition.

How to appraise a diagnostic test.

Urologists frequently encounter problems in making a clinical diagnosis whose resolution requires the use of diagnostic tests. With an ever increasing choice of investigations being available, the urologist often has to decide which diagnostic test(s) will best resolve the patient's diagnostic problem. In this article, we aim to help the urologist understand how to critically appraise studies on diagnostic tests and make a rational choice. This article presents the guiding principles in scientifically assessing studies on diagnostic tests by proposing a clinical scenario. The authors describe a standardized protocol to assess the validity of the test and its relevance to the clinical problem that can help the urologist in decision making. The three important issues to be considered when evaluating the validity of the study are to identify how the study population was chosen, how the test was performed and whether there is a comparison to the gold standard test so as to confirm or refute the diagnosis. Then, the urologist would need to know the probability of the test in providing the correct diagnosis in an individual patient in order to decide about its utility in solving the diagnostic dilemma. By performing the steps described in this article, the urologist would be able to critically appraise diagnostic studies and draw meaningful conclusions about the investigations in terms of validity, results and its applicability to the patient's problem. This would provide a scientific basis for using diagnostic tests for improving patient care.

Hemorrhagic cystitis: A challenge to the urologist.

Severe hemorrhagic cystitis often arises from anticancer chemotherapy or radiotherapy for pelvic malignancies. Infectious etiologies are less common causes except in immunocompromised hosts. These cases can be challenging problems for the urologist and a source of substantial morbidity and sometimes mortality for the patients. A variety of modalities of treatment have been described for the management of hemorrhagic cystitis but there is none that is uniformly effective. Some progress has been made in the understanding and management of viral hemorrhagic cystitis. This article reviews the common causes of severe hemorrhagic cystitis and the currently available management options.

Experience with robotic assisted laparoscopic surgery in upper tract urolithiasis.

OBJECTIVE: Early results indicate that robot assisted laparoscopic surgery (RALS) may be useful in managing upper tract (UT) urolithiasis. We reviewed our experience of managing 50 cases of UT urolithiasis with or without reconstruction using RALS. MATERIALS AND METHODS: We performed a record review of 50 cases of RALS for UT urolithiasis performed in two institutions from July 2006 to June 2009. The RALS procedures included pyeloplasty with pyelolithotomy (29 cases), ureterolithotomy, tailoring and reimplantation for megaureters (5 cases), ureterolithotomy with ureteral stricture reconstruction (1 case), primary UT stone surgeries (8 cases), partial nephrectomy (1 case) and ablative surgeries (6 cases). Data pertaining to indications, operative details, and complications were analyzed. RESULTS: The average operating time was 105 min (86 min-135 min) for pyeloplasty with pyelolithotomy, 140 min (115 min-195 min) for ureterolithotomy, tailoring and ureteroneocystostomy and 106 min (88 min-174 min) for extended pyelolithotomy (5 cases). Mean blood loss was 77 mL (50 mL-250 mL). Stone clearance rate was 93.2%. One case of extended pyelolithotomy had hematuria requiring selective angioembolization. There was one conversion and no other major complication. CONCLUSIONS: RALS for UT urolithiasis is safe and efficacious. It is particularly useful when stone removal is combined with reconstruction. It is a reasonable alternative for treating a solitary partial staghorn or a large pelvic stone including those in pelvic/anomalous kidneys. RALS did not seem substantially better than pure laparoscopy for isolated ureterolithotomy and for nephrectomy for a nonfunctioning kidney. Its role in the treatment of large, multiple or complete staghorn calculi needs further investigation.
