A study on immunohistochemical expression of HER2/Neu and p63 and its association with grade and invasiveness in case of bladder carcinoma.

INTRODUCTION: Bladder cancer is a global disease, ranks as the fourth most prevalent cancer. The incidence and prevalence increase with age. Grade and aggressiveness have been found to be related with different genetic expression and mutation. AIMS: To evaluate any relation of grade and invasiveness of urothelial cancer with varied expression of immune histochemical marker p63 and her2/neu. MATERIALS AND METHODS: The present study was a hospital based prospective cross-sectional study. This Study was conducted from July 2021 to April 2023 in the Urology department of a tertiary care hospital. Total 90 patients undergoing trans urethral resection of bladder tumour (TURBT) were included in this study. RESULT: It was found that, patients who had decreased p63 expression had high grade in tumours (93.1%) compared to patients who were expressing normal p63 (32.8%) and this was statistically significant (p < 0.0001). Tumours with decreased p63 also appeared to be more invasive, 62.1% were found to be muscle invasive. Tumours with her2 neu expression found to be more aggressive in nature, 85.7% had high grade features and 53.6% were muscle invasive. CONCLUSION: Our findings suggest that immunohistochemical expression of HER2/neu positive and decreased p63 expression were associated with high grade and invasiveness in case of bladder carcinoma.

Role of clinical and radiological parameters in predicting the outcome of shockwave lithotripsy for ureteric stones.

INTRODUCTION: Shockwave-lithotripsy (SWL) provides a noninvasive and effective option for the management of ureteric calculi. Several factors may affect the success of SWL. Identification of these predictive factors will both increase the efficacy and decrease the cost. This study was designed to identify factors affecting the outcome of SWL for ureteral stones. MATERIALS AND METHODS: This study was conducted from March 2012 to November 2014 in patients with solitary ureteric calculi who were managed with SWL. Data were analyzed to identify clinical and radiological factors associated with treatment outcome. Success after SWL was described as complete stone clearance or clinically insignificant residual fragments <3 mm at 3 months after SWL. RESULTS: A total of 110 patients with ureteric calculi were divided into two groups depending on the outcome of SWL, Group A (successful - 76%) and Group B (failed - 24%). Stone size, Skin to stone distance (SSD), secondary signs of obstruction, and presence of double J (DJ) Stent, all were significantly associated with the outcome of SWL on univariate analysis. On multivariate analysis, stone size, hounsfield unit, SSD, and DJ stent were the independent factors affecting the outcome of SWL. On Receptor-Operator Characteristic curve analysis, a cutoff value of 8.2 mm for the stone size was found which best predicts a successful outcome, with a sensitivity of 54% and specificity of 96%. CONCLUSION: The findings of this study suggest that Stone size, SSD, the presence of DJ stent, and stone attenuation values are the significant factors that influence the outcome of SWL in patients with ureteral stones.

A rare cause of anuria in a case of pre-B acute lymphoblastic leukaemia.

Renal failure in cases of acute lymphoblastic leukaemia during induction is mainly because of sepsis and tumour lysis syndrome. This 18-year-old man had sudden onset anuria with increase in creatine. At this time, patient did not have any overt signs or laboratory features suggestive of sepsis. Imaging studies documented bilateral hydronephrosis. Ureteroscopy was done, and it showed presence of soft tissue mass obstructing the ureter. On the the left side, it was noted in its middle part and on the right, at the ureteropelvic junction. The mass on the left side was removed under ureteroscopic guidance and was sent for histopathology examination. It was confirmed to be fungal ball on histopathology examination. Though rare, even in immunocompromised patients, bilateral fungal ball should be considered in differential diagnosis in cases of acute leukaemia with sudden onset anuria. We share our experience in managing this case for which there are no clear guidelines.

Monopolar versus bipolar transurethral resection of prostate for benign prostatic hyperplasia: Operative outcomes and surgeon preferences, a real-world scenario.

CONTEXT: Monopolar transurethral resection of prostate (M-TURP) is considered the gold standard for the management of bladder outlet obstruction due to benign prostatic hyperplasia. Its newly introduced modification, bipolar TURP (B-TURP), promises to overcome its most prominent shortcomings, namely bleeding and dilutional hyponatremia. Literature is conflicting regarding merits of B-TURP over M-TURP. AIMS: To find a difference, if any, in perioperative outcomes between M-TURP and B-TURP in a real-wold setting. SETTINGS AND DESIGN: Prospective nonrandomized study. SUBJECTS AND METHODS: Operative outcomes of patients undergoing M-TURP and B-TURP from February 2014 to October 2015 were compared. STATISTICAL ANALYSIS USED: Categorical data were compared by Fischer exact test and numerical data were compared by independent samples Mann-Whitney U-test. P <0.05 was considered statistically significant. RESULTS: The mean size of prostate operated by bipolar technology was significantly greater than those operated by monopolar technology (38.12 ± 9.59 cc vs. 66.49 ± 22.95 cc; P < 0.001). The mean fall in postoperative serum sodium concentration was 0.99 ± 0.76 mEq/L for the B-TURP group as compared to 3.60 ± 2.89 mEq/L for the M-TURP group (P < 0.001). The mean drop in postoperative hemoglobin concentration (P = 0.28) was statistically insignificant, even though larger glands were operated by B-TURP. There were three instances of the transurethral resection (TUR) syndrome in the M-TURP group whereas no TUR syndrome occurred in the B-TURP group. CONCLUSIONS: In spite of various contrary viewpoints in literature, surgeons prefer to operate on larger prostates using bipolar technology. B-TURP definitely reduces the incidence of bleeding and dilutional hyponatremia, making it a contender to replace M-TURP as the new gold standard.

A randomized clinical trial comparing intracorpus spongiosum block versus intraurethral lignocaine in visual internal urethrotomy for short segment anterior urethral strictures.

OBJECTIVES: The primary objective was to compare the effectiveness in pain relief of intracorpus spongiosum block (ICSB) versus intraurethral topical anesthesia (TA) using 2% lignocaine jelly for performing visual internal urethrotomy (VIU) for short segment anterior urethral strictures. MATERIALS AND METHODS: It was a randomized, parallel group controlled trial. Participants are adult patients with a single anterior urethral stricture up to 2 cm in length. Patients were allocated to two intervention groups with thirty patients in each group. For anesthesia of the urethra, Group 1 patients received ICSB whereas Group 2 patients received intraurethral TA using 2% lignocaine jelly before VIU. Patient discomfort was assessed with visual analog scale (VAS) during the procedure and 1 h postprocedure. The increase in pulse rate and the change in systolic blood pressure (BP) during the procedure were recorded. The procedure was considered successful if there was absence of symptoms or signs of recurrent stricture and ability to pass freely 18Fr catheter during urethral calibration at last follow-up. RESULTS: From March 2014 to June 2015, sixty patients were randomized into two groups of thirty patients each. The mean (±standard deviation) intraoperative VAS score was 2.8 ± 1.1 in Group 1, which was significantly less (P < 0.05) than the 5.6 ± 1.7 score in Group 2. The mean 1 h postoperative VAS score was also significantly lower in Group 1 patients (1.0 ± 1.0) than in Group 2 patients (3.2 ± 1.5). The change in pulse rate was significantly greater in Group 2 (21.3 ± 10.1 beats/min) than in Group 1 (10.6 ± 4.6 beats/min, P < 0.05). The change in systolic BP was also significantly higher in Group 2 (16.3 ± 8.6 mmHg) than in Group 1 (9.1 ± 4.4 mmHg, P < 0.05). The stricture-free rate at 6-month after VIU in Group 1 and Group 2 patients were 88.5% and 89.6%, respectively. CONCLUSIONS: ICSB has better pain control with similar complication and recurrence rate than intraurethral lignocaine jelly alone in VIU.

Genitourinary Fistula: An Indian Perspective.

BACKGROUND: In developing countries, obstetric trauma is the most common cause of genitourinary fistulae. But over the last two decades, health care facilities have been improved and the scenario has been changed. PURPOSE: The aim of the present study is to share our experience with genitourinary fistula in terms of mode of presentation, diagnostic modality, and management with the emphasis on the surgical approach and a parallel review of the available literature. MATERIALS AND METHOD: During a 6-year period from January 2007 to December 2013, 41 cases of genitourinary fistula, who admitted and treated in the urology department of a tertiary care center, were retrospectively analyzed for etiology, site, size and number of fistulae, clinical presentation, diagnostic modalities, and management. The literature search was done using the Medline database. RESULT: Mean age of the patient was 27 years (range 16-51). Primary and simple fistulae were common. Obstetric trauma was the most common etiology (56.09 %) followed by iatrogenic (39.03 %). Vesicovaginal fistula was the most common type (78.37 %) and trigone was the most common site involved (51.72 %). 51.35 % of patients were approached successfully by the vaginal route. Ancillary procedures were required in patients for various other associated anomalies at the time of fistula repair. The success rate on follow up was 94.5 %. In the mean follow up of 3 years, 35 patients were sexually active. CONCLUSION: Genitourinary fistula is a frustrating entity with potentially devastating psychosocial consequence. Its management poses a tricky challenge to the surgeon. Accurate and timely diagnosis, adhering on basic surgical principle, and repair by an experienced surgeon provide the optimum chance of cure.

A comparative study of lingual mucosal graft urethroplasty with buccal mucosal graft urethroplasty in urethral stricture disease: An institutional experience.

AIMS: A prospective study to compare the outcomes of lingual versus buccal mucosal graft urethroplasty in patients with long segment anterior urethral strictures disease. MATERIALS AND METHODS: The study included 30 patients for buccal mucosal graft urethroplasty (group I) and 30 patients for lingual mucosal graft urethroplasty (group II) for treatment of long segment (>3 cm) incomplete anterior urethral stricture disease using single-stage dorsal onlay free oral mucosal graft urethroplasty by Barbagli's technique between February 2013 to September 2014. All patients underwent complete evaluation of the stricture including inspection of the oral cavity. RESULTS: The results of urethroplasty in between two group were not significant (P > 0.05) in terms of Qmax (P = 0.63), mean postoperative AUA symptom score (P = 0.83), operative time (P = 0.302) intra operative blood loss (P = 0.708), duration of postoperative hospitalization (P = 0.83), but slurring of speech complications was seen in group II, but not in group I. Long-term complications of salivary disturbance, tightness of the mouth, persistent pain at graft site, perioral numbness, seen only in group I (BMGU). CONCLUSION: LMG urethroplasty is an excellent alternative to BMG urethroplasty with comparable results of urethroplasty and minimal donor site complications.

Laparoscopic Extravesical Lich-Gregoir Ureteroneocystostomy with Psoas Hitch for the Management of Ureterovaginal Fistula in Post-Hysterectomy Patients.

INTRODUCTION: Most commonly ureterovaginal fistula occurs due to surgical injury inflicted to the distal ureter and because of gynaecological procedures. Open surgical repair is a standard procedure and commonly involves ureteroneocystostomy. METHODS: We retrospectively reviewed data of 9 patients, who underwent laparoscopic extravesical Lich-Gregoir ureteroneocystostomy using the psoas hitch procedure for ureterovaginal fistulas following hysterectomy during the period December 2012-August 2014. Transperitoneal laparoscopic ureteroneocystostomy was performed in all cases. RESULTS: The mean operative time was 212 min (range 170-310) and estimated blood loss was 108 ml (range 70-150). Average hospital stay was 5.7 days. Follow-up time was from 6 to 26 months. Postoperative intravenous urography was done after 3 months, which showed patent anastomosis in 8 patients except for 1 patient who had nonvisualization of the ipsilateral renal moiety. Voiding cystogram done at 3 months showed no leakage in all patients. In the postoperative period, 1 patient had recurrent ipsilateral pyelonephritis 2 weeks after surgery, while another patient had febrile UTI. Apart from these no major complications were observed. CONCLUSION: Laparoscopic ureteroneocystostomy with psoas hitch can be performed safely with a success rate compared to that of open surgery but with less morbidity and quick convalescence.

Isolated abdominal wall metastasis from renal cell carcinoma: Unusual presentation.

Fifty-seven-year-old gentleman, who was a known victim of left-sided clear cell renal cell carcinoma (RCC), presented with isolated huge parietal swelling in left anterolateral aspect of abdomen. He had undergone open left radical nephrectomy 2 years back. Parietal swelling was widely excised and histopathology revealed clear cell RCC, nuclear Fuhrman grade 2.

Isolated hydatid cyst in a single moiety of an incomplete duplex kidney.

Isolated hydatid cyst of kidney is very rare. Hydatid cyst of a duplex renal system is even more rare. We report a 13-year old girl with duplex system of right kidney with isolated hydatid cyst in upper moiety. Right nephrectomy was done to cure the condition.

Dilatation and curettage of urinary bladder: A rarity.

Twenty-eight-year-old female while undergoing a medical termination of pregnancy (MTP) encounter complete urethral loss and massive bladder curettage. After resuscitation, she developed continuous urinary leakage followed by progressive decline in urine output. Case is highlighted here because of the massive vesico-urethral trauma because of MTP, leading to permanent urinary diversion.

Squamous cell carcinoma in exstrophy of the bladder.

Exstrophy of the bladder is a rare congenital anomaly with an incidence of about 1 per 50,000 newborns. The malignant potential of the exstrophied bladder mucosa is well known; 95% are adenocarcinomas, and 3% to 5% are squamous cell carcinomas. Most of the malignant tumors (60%) associated with an exstrophy of the bladder occur during the fourth and fifth decades of life. Of the remaining, about 20% each occur after 60 years and before 40 years. Here we present a case in which squamous cell carcinoma developed in an unrepaired exstrophy of the bladder. We present the management of the case and a brief review of the literature.

Leiomyosarcoma of prostate: a rare, aggressive tumor.

Leiomyosarcoma of prostate is a rare, aggressive tumor with bizarre presentation at advanced stage. Though definite treatment modalities are not recommended till now, innovative combined multimodality treatment strategies may help to improve the prognosis of patients with this tumor of poor survival rate. Here we report a case of leiomyosarcoma of the prostate which presented with chest metastasis.

Bladder leiomyoma: a case report.

A case of bladder leiomyoma is reported. A female patient of 35 years old presented with lower abdominal pain, urinary symptoms and episodes of haematuria. USG and CT scan showed a large homogeneous globular mass arising from posterior wall of the urinary bladder occupying a considerable portion of its cavity. Cystoscopy and transurethral resection biopsy confirmed that protruding mass from the bladder wall was leiomyoma. Surgery is the definitive treatment for this rare bladder tumour. Here the tumour was managed successfully by transvesical enucleation.

Laparoscopic ureteric reimplantation of a single-system ectopic ureter in a girl: A rarity.

A 14-year-old girl presented with continuous dribbling of urine along with normal voiding pattern since childhood. Cystourethroscopy showed absence of right ureteric opening, and vaginoscopy showed right ureter opening into vaginal vault. Radiological images showed small right kidney with normal excretory function with single-system ectopic ureter. Patient underwent laparoscopic transperitoneal extravesical ureteric reimplantation. At 3 months' follow-up, intravenous urography (IVU) and micturating cystourethrogram (MCU) showed no obstruction and reflux.
