Objective: To evaluate the efficacy of extracorporeal shockwave lithotripsy (ESWL) in supine trans-abdominal approach for distal ureteric calculi and to determine the variables that could affect the outcome results. Materials and methods: Between November 2019 and January 2021, 172 patients with a solitary distal ureteric calculus were treated with ESWL in supine position with a pronated shock wave head against the anterior abdominal wall. The outcome of treatment evaluated and the clinical and radiological findings, as well as stone characteristics, were reviewed and correlated with the stone-free rate (SFR). Results: Overall SFR was 84.84% (140/165). Those with stone clearance, 83.57% (117/140) cleared after one session and 16.42% (23/140) needed more than one session. Only three factors had a significant impact on SFR, that is stone length, stone width, stone attenuation. For stone length ⩽ 9 mm SFR was 93.44% (114/122) compared to 60.46% (26/43) for stone length of 10–12 mm ( p Conclusion: Supine trans-abdominal ESWL is a new, effective and safe form of treatment for distal ureteric calculi. The stone length, stone width along with stone attenuation were the only significant predictors of stone free status in supine position.

Background: PCNL outcomes among urologists are different because of the vast heterogeneity in the methods for clinical, academic characterisation and evaluation of surgical outcomes of nephrolithiasis. So assessing the preoperative factors that affect SFR (Stone Free Rate) and complications is critical. Heterogeneity in reporting of PCNL outcomes among different centres has led to the invention of nephrolithotomy scoring systems based on preoperative parameters to better counsel patients contemplating PCNL. The Guy’s stone score, CROES nomogram and the S.T.O.N.E score are seen as predictors of stone-free status (SFS) and complications after PCNL. No universally accepted stone scoring system for predicting SFR and complications after PCNL exists. This is a prospective observational study to compare and analyse the existing stone scoring systems (SSS) and to assess the best parameters to predict PCNL outcomes concerning SFR and complications. Methods: This study is done in a tertiary level institute in eastern India which included 200 patients who underwent PCNL from November 2019 to November 2021. The relevant operative parameters were documented and compared to the preoperative factors with the help of nephrolithotomy scoring systems. Results: The Guy score, CROES nomogram and S.T.O.N.E. score were accurate in predicting the SFR in patients undergoing PCNL. A new IPGMER preoperative stone scoring system based on the most relevant parameters could be used as an alternative to predict SFR and complications in PCNL. Conclusion: The Nephrolithometry scoring systems are simple, straightforward and easily reproducible systems to classify the severity of nephrolithiasis and to stratify the complexity of PCNL.

Background: Prostate cancer development and progression to androgen-independent disease is correlated with increased expression of growth factors and receptors capable of establishing autocrine and/or paracrine growth-stimulatory loops. Overexpression of the Her2/neu receptor tyrosine kinase has been associated with the progression to androgen independence in prostate cancer cells. Objective: Our primary aim was to investigate the frequency of HER2/neu amplification in prostate biopsy specimens in newly diagnosed metastatic carcinoma prostate and its correlation to progression of androgen independent carcinoma. Materials and Methods: In our study, expression of HER2/neu was carried out by immunohistochemical analysis in TRUS biopsy specimen of newly diagnosed metastatic carcinoma prostate. Results: Out of 36 patients, seven (19.4%) showed her2neu overexpression on immunohistochemical staining. Five out of seven (71%) were associated with higher histological grade >7 at diagnosis ( p 0.05). Conclusion: Overexpression of her2/neu was associated with high grade carcinoma prostate at diagnosis, however progression to castration resistant stage was not related with her2neu expression.

Introduction and objective: Nephrectomy leads to derangement of renal function and various adaptive changes by the remaining kidney over a period of time. This study is performed to evaluate the amount of derangement of renal function in donor and radical nephrectomy, how much the remaining kidney adapts over a period of time and the time taken for stabilisation of renal function. Method: A total of 60 patients who underwent nephrectomy (Radical/Donor) were followed up for 12 months with serial estimation of renal function and was compared with preoperative renal function. Data was analysed with statistical analysis. Result: Patients who underwent radical nephrectomy had 37% initial decline in renal function which was later stabilised at 19% lower than baseline value. Patient who underwent donor nephrectomy had initially 39% decline in renal function which was later stabilised at 24% lower than normal. Conclusion: Removal of functional renal tissue led to reduction of renal function. This decline is more evident in the initial post-operative period and then begin to stabilise over months. The greater is the amount of normal tissue removed, the greater is the reduction of renal function and more time it will take to stabilise, increasing overall morbidity of the patient. This study suggests that even patients with normal GFRs should be followed up postoperatively to determine their ultimate renal functional outcomes.

Objectives: Evaluation of safety, efficacy, and feasibility of emergency extracorporeal shockwave lithotripsy (eESWL) in combating obstructing stones with colic on emergency basis. Materials and methods: From November 2019 to November 2021, 102 subjects underwent emergency ESWL for obstructing ureteric and renal stones with colic within 24 h of presentation. Results: Patients in this study belonged to age group of 18–67 years with mean being 39 years consisting of 85 males and 22 females (M:F = 85:22). Mean stone dimensions were 8.26 mm in length and 7.65 mm in width. A total of 42 patients had their stone in kidney or upper ureter while 24 patients had stone in mid ureter and remaining patients ( n = 36) had stone in lower ureter. About 65 patients had their stone completely cleared after single ESWL session while 20 patients required multiple sessions to achieve complete clearance. Of these 17 patients (16.67%) were not rendered stone free even after three sessions and had to undergo ureteroscopic lithotripsy (URSL). Overall Stone Free Rate (SFR) was 83.33%. For stone attenuation of ⩽900 HU, SFR was 97.18% while for >900 HU it was only 51.61%. Conclusion: eESWL is safe, feasible, and efficacious noninvasive alternative for definitive management of obstructing ureteral and renal stones with colic as far as stone clearance and rapid and definitive pain relief are concerned and that too with very minimal morbidity without the need for admission and hence can reduce the prolonged waiting period for endoscopic stone surgery in any high-volume tertiary care hospital. Length, width, and attenuation of stone were found to be the main factors dictating the success of eESWL.

Background: Percutaneous Nephrolithotomy (PCNL) is advanced minimally invasive endoscopic procedure for management of renal stones. There are limited studies showing early changes of renal function following PCNL. Knowledge of the changes of renal function after PCNL may act as a guide during postoperative follow-up, especially those at risk.Methods: From 1st November 2016 to 30th October 2018, patients were subjected to PCNL under general anaesthesia. A preoperative 99 m Tc DTPA renal scan was performed & repeated on 3rd & 14th post-operative day. Results: Total 102 patients were divided into 19-32, 33-46 and 47-60 years group. At post-operative day-3 GFR of operated kidney reduced significantly in all 3 age groups (p=.05). Conclusions: Nephrotoxic drugs, contrast agents, ESWL etc. has negative influence on renal function. These should be avoided to prevent further trauma of operated kidney in early post-operative period.

Neoplasia of the renal pelvis in duplex kidneys is extremely rare, especially in complete renal ureteral duplex cases. A 46-year-old aged male patient had presented with intermittent haematuria for the last seven months. A mildly enhancing well-defined, lobulated mass arising from the pelvis of lower moiety of right kidney was found on evaluation. Confirmatory findings of a renal pelvic malignancy couldn’t be obtained. Infective condition like pyelonephritis couldn’t be excluded. To clear the diagnostic dilemma, flexible ureteroscopy was done which revealed the renal pelvic malignancy. Right lap assisted radical nephroureterectomy was done. Histopathology was suggestive of transitional cell carcinoma. The increased incidence of chronic infection, obstruction and stone formation may be instrumental in producing a higher incidence of renal pelvic tumours in patients with anomalous kidney. Diagnosing a neoplasia originating from a duplex kidney is difficult and often a multiple battery of investigations like intravenous pyelogram, ultrasonography and rigid ureteroscopy may not be useful. Considering the fact that tumour recurrence is high in the ureteric stump after local resection, a total nephroureterectomy seems to be a better treatment choice. Flexible ureteroscope might be the saviour in such doubtful clinical situations to confirm our diagnosis beyond doubt. Partial nephrectomy cannot be recommended unless long-term follow-up reports of such cases are available.

The objective of our study was to evaluate the detection rate of prostate cancer by digital rectal examination (DRE) and serum prostate-specific antigen (PSA) levels followed by standard 12-core transrectal ultrasound (TRUS)-guided prostate biopsy.After screening of patients presenting with lower urinary tract symptoms (LUTS) using DRE and serum PSA level, we enrolled patients for TRUS-guided 12-core prostate biopsy. Indications included PSA level ≥4 ng/ml and/or suspicious DRE findings. A retrospective analysis was done to find out the correlation between suspicious rectal examination and various serum PSA levels in detection of cancer prostate.A total of 847 patients were screened for cancer prostate during our study period (May 2012-February 2020). Among them, 823 patients who underwent prostate biopsy were analyzed. Prostate cancer was detected in 330 cases (40.09%). Mean age of patient (years) with and without prostate cancer was 66.25 ± 9.45 and 64.3 ± 8.96 years, respectively. Median value of serum PSA in patients positive for cancer was 33 ± 260 ng/ml compared to patients without cancer, who had a median value of 9 ± 64 ng/ml (P-value of0.0001). The detection rate of cancer based on suspicious DRE findings irrespective of PSA was 52.18% (251/481), compared to 45.46% (311/684) using a PSA cut-off of ≥4.0 ng/ml alone. Among 330 patients with positive biopsy, 19 (5.75%) had a PSA level4 ng/ml and they were identified based on suspicious DRE alone.Suspicious DRE was significantly associated with detection of prostate cancer across all PSA levels. Patients with PSA4 can harbor prostate malignancy and such cases can be detected by use of DRE in screening of all patients with LUTS.

Multicystic Dysplastic Kidney (MCDK) is a relatively common cystic disease of kidney which may be associated with various urogenital abnormalities. Here, authors encountered a case of 16-year-old male who presented with left side abdominal pain and lump. On evaluation, he was found to be growth-retarded with chronic renal failure. Imaging studies revealed left MCDK with contralateral pelvic kidney with ectopic ureter opening in prostatic urethra. This patient also had calculus in right ectopic ureter near its opening in prostatic urethra. The calculus was surgically removed; however, he required dialysis as there was no improvement in renal function. This conglomeration of anomalies is extremely rare and a dilemma exists not only in diagnosis but also in therapeutic decision making. Every case of MCDK or ectopic ureter should be further investigated to detect associated abnormalities, for timely management.

Purpose: Urolithiasis is a common medical condition and the treatment is mainly minimally invasive methods. There exists no specific guidelines for the treatment of radio-opaque solitary non lower calyceal kidney stones of 10–20 mm in literature and no head to head study comparing both the procedures. Hence, this study was performed to have a specific guide for the treatment of such stones. Materials and Methods: This study, included all patients aged >18 years, with solitary radiopaque calculi of 10–20 mm size in upper or middle calyx or pelvis of the kidney. A total of 105 patients were assigned to receive extracorporeal shock wave lithotripsy (ESWL) or mini-percutaneous nephrolithotomy (PCNL) for treatment of stone were enrolled in the study and the results were compared in terms of retreatment, stone-free rate (SFR), and complications. Results: The SFR was statistically higher in the mini PCNL group for all locations. The SFR for the ESWL group was low after 1st session; however, it increased with multiple sessions. We had a total of 9 complications in both groups, which was statistically insignificant. Conclusion: This study showed that the mini PCNL is a viable, safe option for the treatment of 10–20 mm non lower calyceal stones, having superior SFRs compared to ESWL with statistically insignificant complications. It can be offered as first-line option for the management of such stones.

Composite phaeochromocytomas (CP) are extremely uncommon adrenal medullary tumours where phaeochromocytoma coexists with another adrenal medullary tumour also of neural crest origin. CP includes combination of phaeochromocytoma along with a component of neuroblastoma, ganglioneuroblastoma, ganglioneuroma, benign nerve sheath tumour or a malignant peripheral nerve sheath tumour (MPNST). Here we describe the morphological and immunohistochemical details of a case of CP with MPNST in a 30 years old lady, without history of neurofibromatosis. Only 6 cases of CP with MPNST have been reported so far. We have tabulated a summary of these prior published cases of phaeochromocytoma with MPNST. To our knowledge, this is the first literature review describing the clinico-pathological characteristics of these rare tumours.

Teratomas are tumors consisting of two or three germ layers, seen commonly during childhood. Mature teratomas are benign and demonstrate well differentiated tissues such as sebaceous glands, hair, and teeth. Bladder is a very rare extragonadal site for teratoma, moreover so in adults. Presentation may vary from with irritative lower urinary tract symptoms or urinary retention to pilimiction (passage of hair in the urine). We hereby present a case of mature teratoma of the urinary bladder, with a classical symptom of pilimiction, in a 22-year-old male patient, which to our knowledge is the first male case reported in the literature.

Surgical repair is usually done in intraperitoneal bladder perforation, whereas in genitourinary trauma reports of conservative management exist. We hereby, present a case of an old man with carcinoma prostate having intraperitoneal urinary bladder perforation with enterovesical fistula that was successfully managed non-operatively and conservatively.

Objective Purpose of our study was to aggregate and analyse rare cases of Ectopic Ureter (EU), their association with other anomalies, clinical features, diagnosis and management. Material and methods A total of nine patients with rare presentation of EU were evaluated. Combination of endoscopic and imaging modalities was used as required to define the anatomy and devise the best surgical approach in these cases. Results Among six females and three males with EU, four cases had bilateral EU, four unilateral EU and one case had EU of a solitary kidney. Urinary incontinence was encountered in five cases including one male patient whilst other cases presented with varied clinical features and associated anomalies. Two patients had anorectal malformations, and two had uterine anomalies in the form of bicornuate uterus. Other patients had multiple rare associations such as triplication of ureter, bilateral absence of seminal vesicles with infertility, multicystic dysplastic kidney, ureter draining in uterus, renal failure, absence of bladder trigone, and hypospadias etc. Ureteric reimplantation was performed in four cases, two required ureteroureterostomy, another two had undergone upper pole nephrectomy and in one case renal transplant had been carried out owing to chronic renal failure. Conclusion EU is among group of those congenital entities which remain shrouded until adulthood, when symptoms become distressing. Fortunately, prognosis is favourable after surgical correction, in spite of its rarity. Complexity arises when other associated anomalies are identified.

Mucinous adenocarcinoma of the renal pelvis is a rare tumor constituting < 1 % of all tumors involving the kidney. We are presenting the case report of a 45-years-old female who presented with pus discharging sinus from the scar of previous surgery after 2 years of initial surgery. On CECT, the left kidney showed heterogeneous space-occupying lesion of size 10x6 cm. The patient underwent cytoreductive excision of mass followed by adjuvant radiotherapy. The patient was doing well and asymptomatic till 8 months of follow-up but after 8 months, she presented with recurrence and died after another 4 months. To our knowledge, none of the previous papers reported discharging sinus as a mode of presentation for mucinous adenocarcinoma of the kidney. The outcome of the patientwith relevant literature is being discussed here.

Background: Effects of percutaneous nephrolithotomy (PCNL) operation on ipsilateral renal function are widely known but functional changes in opposite kidney are limited. Authors have conducted this study to evaluate the impact of PCNL operation on the contralateral side during early post-operative period.Methods: From 1st November 2016 to 30th September 2018, those patients presented with unilateral renal stone disease were enrolled. After exclusion they were subjected to PCNL operation under general anaesthesia. Along with preoperative period, 99 m Tc DTPA renal scan is repeated at 3rd and 14th post-operative period.Results: Out of 121 patients enrolled we included 96 patients after exclusion. They are divided into 3 age groups, 19-32, 33-47 and 48-60 years. The mean GFR at pre-operative, post-operative day-3 and 14 of normal kidney in these 3 age groups are 47.32, 47.63 and 42.32 ml/min, 44.29, 45.78 and 40.63 ml/min and 47.10, 48.47 and 41.01 ml/min respectively. At post op day-3 there are reduction of mean GFR in all age groups but statistically not significant (p >0.05). At post-operative day-14 GFR improved towards the pre-op value but the change is also not significant (p >0.05).Conclusions: There are reduction of GFR of contralateral normal kidney following PCNL operation in early post-operative period. So, along with operated kidney normal kidney also showed decrease GFR. It is better to avoid further trauma in post PCNL patient like avoidance of using nephrotoxic medication, contrast agents, ESWL, etc. This study can guide us to avoid further trauma of any kidney.

Introduction: Office cystourethroscopy is one of the common and most frequent urological procedures. Pain and anxiety during the procedure might lead to noncompliance and incomplete cystoscopic examination. Negotiating cystoscope through external sphincter is the most painful and uncomfortable distressing part of cystoscopy. To overcome this, manual compression of irrigation bag during cystoscopy has been used and found to be helpful. Numerous other methods were also studied. Despite these, cystoscopy is still painful and causes anxiety in patients. External sphincter gets relaxed naturally during the act of micturition. Based on this principle, pain and anxiety were studied with voiding instruction during cystourethroscopy. Objective: To study the effect of voiding instruction on anxiety and pain during cystourethroscopy using the Hamilton Anxiety Rating Scale (HAM-A) and visual analogue scale (VAS), in a well-matched Eastern Indian male patient population in a prospective, randomized pattern. Methods: A total of 100 male patients were recruited from those who underwent cystourethroscopy examination in SSKM Hospital and were prospectively randomized into two groups: cystoscopy with or without voiding instruction. Pre- and postprocedure HAM-A score and postprocedure VAS score were recorded. Results: The mean postprocedural pain (VAS) score between voiding instructed and noninstructed groups reached statistical significance: 3.06 ± 1.98 (Range, 2–5) and 5.16 ± 2.86 (Range, 4–8), respectively (P < 0.001). Preprocedure HAM-A score was similar between both groups. Postprocedure median HAM-A score was statistically significantly lower (mean 17.86 ± 2.8 vs. 19.76 ± 3.12; P < 0.001) in voiding instructed group. Conclusion: Pain and anxiety level during cystourethroscopy examination in males can be significantly reduced when the patient is instructed to void during cystourethroscopy examination.

We report a case of a 43-year-old man who developed intractable hematuria after percutaneous nephrolithotomy. Angiography detected a pseudoaneurysm arising from the lower polar artery; however, embolization could not be performed because of unfavorable vascular anatomy. A percutaneous thrombin injection under ultrasound guidance initially controlled the bleeding, but hematuria subsequently recurred as a result of recanalization of the aneurysm. The case was successfully managed with ultrasound- and fluoroscopic-guided direct injection of cyanoacrylate glue into the pseudoaneurysm.

End-to-end anastomotic urethroplasty (EEA) for traumatic bulbar urethral stricture has excellent long-term success rate. We encountered a patient with obliterative bulbar stricture and persistent phlegmon in perineum resulting from straddle injury. Phlegmon-excision and EEA was performed, which ended up in recurrence. Thorough excision of recurrent nodules & scar with stage-I urethroplasty was performed using ‘scrotal shutter flap’. Histopathology of phlegmon of first surgery and nodules & urethral margins of second revealed amyloidosis. Stage-II urethroplasty was performed 3-months later after which he is well at 24months follow-up. This is the first case of perineal-urethral amyloid associated with trauma. Etiology is elusive.

Objective: Development of castrate resistant prostate cancer (CRPC) indicates progressive disease with poor survival. Docetaxel has variable response with a good proportion of nonresponders. Neuroendocrine differentiation, hypothesised as one of the mechanisms behind development of CRPC, can be assessed by plasma Chromogranin A (CgA). We evaluated the clinical importance of circulating CgA in CRPC patients receiving Docetaxel. Methods: Plasma CgA was assessed by ELISA in 14 patients with CRPC receiving 3-weekly docetaxel. Baseline PSA, baseline CgA, PSA response, CgA response and clinical response to chemotherapy were evaluated and analysed. Results: Increased plasma CgA was observed in 64.3% of patients. There was no correlation between baseline CgA and PSA. Two patients with PSA < 10 ng/ml had elevated CgA. Baseline CgA was not influenced by variables such as site of metastasis and time to develop CRPC status. Seven patients (50%) had PSA-response and 5 (36%) CgA-response. In 4 patients PSA response and CgA response were discordant. Compared to men with normal baseline CgA, a higher proportion of those with elevated baseline CgA had PSA response (55% vs 40%), symptomatic response (66% vs 40%) and radiological response (55% vs 20%). Two patients with symptomatic response had only CgA response. Three patients having disease progression despite PSA response had increasing CgA. Conclusions: CgA and PSA are complementary tumour markers in CRPC. CgA may help in predicting the response of docetaxel therapy. Rising CgA during therapy may be associated with bad prognosis whereas CgA response is likely to be associated with clinical response.

Background: Large pelvic masses pose unique diagnostic and therapeutic challenges due to varied aetiology, paucity of characteristic imaging features, lack of therapeutic algorithms and surgical difficulties in resection inside the narrow confines of the pelvis with close proximity of vital structures. Methods: Records of 22 patients with large pelvic masses in the last six years were analysed. Their demographic and clinical features were noted, along with imaging features, preoperative biopsy, surgical procedure, intraoperative difficulties, complications, adjuvant therapy and outcome. Results: There were 14 men and 8 women with a median age of 45 years. Presenting symptoms were abdominal mass, pain, lower urinary tract symptoms, urinary retention and constipation. Imaging was mostly unable to determine the organ of origin of the tumour. Histopathology revealed pelvic fibromatosis (2), chondrosarcoma (1), liposarcoma (1), haemangioendothelioma (1), lymphangioma (2), fibroleiomyoma (1), leiomyosarcoma (3), schwannoma (4), malignant nerve sheath tumour (1), rectal gastrointestinal stromal tumour (1), retrovesical hydatid cysts (3), sacral chordoma (1) and Ewing’s sarcoma (1). In 5 patients complete excision was not possible because of extension into vital structures. Fifteen patients were alive at 1–5 years of follow-up. Conclusions: Urologists, being the ‘gatekeepers of the pelvis’, are usually involved in the management of large pelvic masses. Good outcome can be achieved with careful surgical planning.

The aim of this study was to assess the efficacy of desmopressin nasal spray compared with diclofenac given intramuscularly in patients with acute renal colic caused by urolithiasis. The study included 72 patients randomized into three different groups: group A received desmopressin (40 mg, nasal spray), group B diclofenac (75 mg) intramuscularly and group C, both desmopressin and diclofenac. Pain was assessed using a visual analogue scale at baseline, 10, 30 min and 1 h after administering the treatments. Rescue analgesia was given at 30 min if needed. On admission, the pain level was the same in all three groups (group A 85; and group B and C 90 each). At 10 min the pain decreased minimally in all the groups but more in group B and C (group A 80 and group B and C 70 each). At 30 min pain scores were 75, 37.5 and 40 for group A, B and C, respectively, indicating that there was no significant pain relief in desmopressin group. Rescue analgesic had to be given to all patients in group A and two patients in group B and three patients in group C. Pain relief in the desmopressin only group was significantly less at 1 h even after rescue analgesia (pain scores of 27.5, 15 and 20 for group A, B and C respectively). Intranasal desmopressin is not an effective analgesic in renal colic: exerts mild analgesic effect over a period of 30 min. It does not potentiate the effect of diclofenac.

Background and Objectives: Patients with chronic kidney disease (CKD) are more prone for bleeding following percutaneous renal intervention, as compared to those with normal renal function. Causes are multi-factorial. Finding multiple aneurysms away from the site of renal intervention following initial angioembolization for hemorrhage is very unusual in these patients. Materials and Methods: Clinical and radiological findings of all the patients who underwent renal angiography for post-intervention bleed for a period of 5 years were reviewed and analyzed. Results: A total of 29 patients required angiography for post-intervention hemorrhage. Six patients had recurrence of hemorrhage for which they underwent repeat angiography. Four of these patients had appearance of multiple new aneurysms away from the site of percutaneous nephrostomy (PCN)/percutaneous nephrolithotomy (PNL) puncture and the site of previous bleeding. All the patients had CKD (creatinine >2.5 mg/dl). They were on prolonged preoperative urinary diversion and had polymicrobial urinary infection. Three patients had candiduria. None of these patients had re-bleeding after repeat embolization and treatment with antibacterial and antifungal agents. Conclusions: Development of multiple aneurysms away from the sites of punctures in patients with CKD following percutaneous intervention is very unusual. Its causation including infection with bacteria and fungus, reaction of embolizing material, and angiopathy needs to be explored.
