A Comparative Study of Continuous Versus Interrupted Suturing Technique in Creating a Vascular Access for Hemodialysis: An Institutional-Based Experience.

Background Arteriovenous fistulas (AVFs) are considered the first and best access for patients with end-stage renal disease who need permanent vascular access for hemodialysis over arteriovenous grafts and central venous catheters for reasons that have been well-established. Poor early patency rates pose the biggest challenge in creating vascular access as they cause increased morbidity and economic/psychological concerns among patients. To minimize such effects, it is critical to use a patient-centered approach and carefully choose patients for AVF access creation. This study aimed to compare the primary patency of distal vascular access provided by continuous suturing versus that provided by interrupted suturing. Methodology This prospective study was conducted in the urology department of a superspecialty, tertiary care center from November 2021 to November 2022. Patency was assessed immediately after surgery (on the table), one month later, and six months later by palpating thrill and auscultating bruit. A total of 50 patients between the ages of 18 and 70 years who met the inclusion criteria were randomly assigned to two groups of 25 each. Results The baseline characteristics of both groups were comparable. At six months (p = 0.09), the continuous suturing group was observed to be somewhat better than the interrupted suturing group, with no significant difference in immediate and one-month patency rates. When compared to the continuous suturing group, the primary patency failure rate was significantly higher in the interrupted suturing group. Conclusions Thus, under appropriate circumstances, continuous sutures can be performed with greater ease, resulting in anastomosis that is as patent as that performed with interrupted sutures.

De Novo Lower Urinary Tract Symptoms in COVID-19 Patients.

Background and objective Since early 2020, the novel coronavirus disease 2019 (COVID-19) has turned into a global healthcare concern. The usual clinical presentation of COVID-19 infection includes myalgia, headache associated with pyrexia, and sore throat. Our study aimed to assess the severity of lower urinary tract symptoms (LUTS) in COVID-19 patients and determine its correlation with the prognosis of the disease. Methods We conducted an observational study in the COVID-19 care unit at a tertiary care teaching center in Rajasthan on patients diagnosed as COVID-19-positive. The overactive bladder (OAB) symptom scoring system for LUTS and the CT scoring system for lung involvement in COVID-19 patients were used to evaluate the sample population. Results While our findings showed a non-significant association between OAB and CT score (p>0.05), correlation analysis revealed that the length of hospital stay was significantly longer and oxygen needs were significantly more frequent with severe LUTS. Conclusions Based on our findings, de novo LUTS, particularly storage symptoms, may be present in COVID-19-positive cases, and the severity of these symptoms may have an impact on the patient's length of stay in the hospital. Hence, doctors and other medical professionals should consider COVID-19-related bladder dysfunctions such as de novo LUTS as part of COVID-19 symptomatology.

Retrospective comparison of outcomes of laparoscopic pyeloplasty using barbed suture versus nonbarbed suture: A single-center experience.

INTRODUCTION: laparoscopic pyeloplasty is an important tool in urology armamentarium. The most important & also the difficult part of this surgery is intracorporial suturing and knotting. There are only a few reports of knotless Barbed sutures for upper tract reconstruction. We report the comparative outcomes of Laparoscopic Pyeloplasty with barbed suture vs non barbed sutures used for uretero-pelvic anastomosis. MATERIALS AND METHODS: We retrospectively reviewed patients' records that underwent Laparoscopic pyeloplasty at our Institution from January 2013 to May 2014. Total 37 patients were underwent LP in this period. Whole of the procedure was same as conventional LP except suture material. 3-0 barbed suture was used in 21 patients and 3-0 vicryl used in 16 patients for uretero-pelvic anastomosis and continuous suturing technique was employed. Patients' demographics, total operative time, intracorporial suturing time, post operative complications, symptoms & renal isotope scan were recorded. RESULTS: Average total operative time was significantly less in barbed suture group vs vicryl group (162 vs 208 minutes) (p=0.0811). Average time taken for intracorporial suturing was 31.2 minutes vs 70 minutes (p=0.0576). 1 patient developed post operative urine leak which persisted for 5 days in barbed group (4.76 %) vs no leak in vicryl group. Most common complication was UTI presented in 2 patients (9.5 %) vs 2 in vicryl (12.5%). JJ stent was removed at 4 weeks. Median follow up was 3 months with 7 patients lost to follow up. None of the patients found to have obstructive drainage or deterioration of split function on follow up isotope renogram at 3 months. CONCLUSIONS: In this study, Laparoscopic pyeloplasty with barbed suture has acceptable outcome when compared to conventional non barbed suture on short term basis. Laparoscopic Pyeloplasty with barbed suture can potentially become the standard approach in near future.

The effect of closure versus nonclosure of lingual mucosa graft harvest site on postoperative morbidity in augmentation urethroplasty: A comparative study.

OBJECTIVES: The objective of this study is to compare postoperative morbidity of closure versus nonclosure of the lingual mucosa graft (LMG) harvest site in augmentation urethroplasty. MATERIALS AND METHODS: From January 2015 to November 2016, a total of 42 patients who underwent LMG urethroplasty randomized in 2 groups. In Group 1, donor-harvesting site was left open while in Group 2, donor site was closed. Self-made questionnaires were to assess postoperative pain, difficulty in tongue protrusion, swelling and numbness in graft harvest site, speech impairment, and difficulty in tolerating liquid and regular diet. RESULTS: Mean visual analog scales score was 7.1 in Group 1, and 7.9 in Group 2 on day 0, which was statistically significant. Nearly 90.47% of patients in closure group and 95.23% in nonclosure group were able to swallow liquid diet on day 0 (P = 0.5604). On day 3, 95.71% of patients in Group 1 and 80% in Group 2 were able to swallow soft diet (P = 0.1604). Numbness was present in 80.95% Group 1 and 71.42% in Group 2 on day 0, which improved to 28.57% pts in Group 1 and 33.33% in Group 2 on day 3. On day 3, slurring of speech was more frequent in closure group (80%). However, at the end of a week, there was no difference in both groups. Saliva production was significantly increased in Group 1 in the 1st week. CONCLUSION: Long-term morbidities of closing or nonclosing the LMG donor site are similar, but in short term, there is less pain, less edema, early recovery of tongue movements in nonclosure groups.

Linguistic and cultural validation of Ureteral Stent Symptom Questionnaire in Hindi.

INTRODUCTION: In the year 2003, Joshi et al. developed a validated outcome assessment tool to measure the ureteral stent-related symptoms. The original English language Ureteral Stent Symptom Questionnaire (USSQ) has been validated in various languages worldwide. Our objective was to develop the USSQ in Hindi, a commonlyused language in India, by validating it in patients undergoing ureteroscopic lithotripsy. MATERIALS AND METHODS: A final Hindi version of the USSQ was derived from the original English version to apply to the study population by translation, back translation, and face-to-face interviews. The Hindi and English versions were completed by 70 patients undergoing ureteroscopic lithotripsy with stent in situ, on postoperative days 7 and 8, and 4 weeks after stent removal. Similarly, discriminant validity was checked among 50 healthy individuals. A detailed statistical analysis was used to correlate results (Cronbach's α coefficient, Spearman's correlation, and Mann-Whitney U-test). RESULTS: A total of 70 patients were enrolled in the study and 61 completed the final assessment. The median age was 35 years (range: 18-60 years). The USSQ domain scores with the stent in situ were higher than poststent status. The test-retest reliability checked by Cronbach's α coefficient (>0.44) and Spearman's correlation coefficient (>0.44) were acceptable to good. We found high discriminant validity of the questionnaire between patients with stent and the healthy controls (P < 0.05). CONCLUSION: Our results demonstrate satisfactory validity for the Hindi version of the USSQ for the assessment of quality of life in patients with stent. This is ready for application in the clinical studies and the future stent-related research in Hindi language.

Histopathological changes in oral mucosa in cases of failed augmented urethroplasty.

OBJECTIVE: Histopathological changes in oral (buccal or lingual) mucosa after exposure to urine are still not completely understood. We evaluated these changes in free oral mucosal graft integrated in human urethra. MATERIAL AND METHODS: Total 19 patients with recurrent urethral stricture after oral mucosa urethroplasty (buccal 12 and lingual 7) were prospectively evaluated. Intraoperatively integrated buccal or lingual mucosal graft sample that was previously engrafted to urethra was completely excised along with healthy oral mucosa, and it was sample processed for histopathological evaluation by dedicated pathologist. Preoperative clinical data were properly collected from all the study participants. RESULTS: The mean age of the patients was 30 years, and the mean preoperative peak flow rate was 4.2 mL/s. Etiology of initial stricture was idiopathic in 13 (68.42%) patients and traumatic urethral catheterization in 6 (31.58%) patients. Mean interval from previous buccal mucosal urethroplasty to current urethroplasty was 21.9 months (range 12-46 months). On repeat urethroplasty, the mean stricture segment length was 59.2 (38-77) mm [60.08 (38-74.6) mm buccal, and 58.32 (39.6-77) mm lingual]. These integrated oral mucosal grafts maintained their histopathological characteristics in all patients except some kind of changes like submucosal fibrosis in seven (58.33%) cases of buccal and vacuolar degeneration in five (71.42%) cases of lingual mucosal urethroplasty. CONCLUSION: Histopathological characteristics of integrated oral (buccal and lingual) mucosal grafts were maintained even on exposure to urine except some changes like submucosal fibrosis and vacuolar degeneration. Impact of these changes require further research.

Primitive neuroectodermal tumor of kidney with Level III inferior vena cava thrombus.

Primitive neuroectodermal tumor (PNET) of the kidney is an extremely rare renal neoplasm with only about 50 reported cases in the literature. These tumors behave aggressively and carry a poor prognosis. A 22 years female patient presented with right lumber and right hypochondrium lump of 4 months duration. Commutated tomography revealed large right renal mass with renal vein and inferior vena cava (IVC) thrombus. Magnetic resonance imaging abdomen demonstrated the extension of tumor thrombus up to the junction of hepatic vein and IVC. Preoperative percutaneous needle biopsy was performed. Histopathology demonstrated small round to oval cells with scanty cytoplasm and cells are arranged in clusters. Immunohistochemical staining demonstrated a highly specific cluster of differentiation 99, confirming the diagnosis of a PNET.

Assessment of factors affecting the spontaneous passage of lower ureteric calculus on the basis of lower ureteric calculus diameter, density, and plasma C- reactive protein level.

INTRODUCTION: The study aimed to evaluate the factors which affect the spontaneous passage of lower ureteric calculus on the basis of noncontrast computed tomography kidneys, ureters, and bladder (NCCT KUB) stone diameter, stone density, and plasma C-reactive protein (CRP) level. MATERIALS AND METHODS: We conducted a prospective study of 200 patients with lower ureteric calculus 5-10 mm in size, from October 2015 to December 2016. All patients underwent NCCT KUB region with a 5 mm axial and reformatted coronal section. Edema just above the calculus and rim sign at the level of calculus and density of calculus is evaluated. Only scan with isolated, unilateral, solitary ureteric calculus was included in the final analysis and monitored up to 4 weeks, and plasma CRP is estimated in all patients to determine the clinical outcome. RESULTS: A total of 200 patients (145 males, 55 females; mean age ± standard deviation, 34.73 ± 10.29) were included in the study. Lower ureteric calculus between 5-7 mm passed in 70% and 7-10 mm passed in 40%. There was 18% underestimation of maximum stone diameter in axial plane as compared to coronal plane. For spontaneous passage of calculus, craniocaudal (CC) diameter is more reliable then axial in NCCT. Rim sign and edema is absent in 64% of those passed spontaneous calculus. CRP level more than 2.45 mg/dl has low spontaneous expulsion rate. The stone with different HU passes through the ureter with same rate. CONCLUSION: Plasma CRP level and CC diameter and absence of rim sign on NCCT KUB are more reliable factors then density for spontaneous passage of ureteric calculus.

Technique for single-stage reconstruction of obliterative or near-obliterative long urethral strictures in circumcised patients.

Purpose: To report our initial experience with urethral reconstruction using a combined dorsal lingual mucosal graft (LMG) and ventral onlay preputial flap for long obliterative or near-obliterative strictures in circumcised patients. Materials and Methods: This was a retrospective study of 10 patients from January 2015 to June 2017 with long obliterative or near-obliterative anterior urethral strictures and circumcised prepuces. All patients underwent a combined approach using a dorsally LMG and a narrow preputial onlay flap ventrally to create a 26-30 Fr. neourethra over a 14-Fr Foley catheter. Success was defined as no requirement for additional urethral instrumentation. The follow-up period ranged from 6 to 32 months. Results: The patients ranged in age from 17 to 44 years (mean, 32.3±9.59 years) and stricture length ranged from 9 to 12.5 cm (mean, 10.77±1.15 cm). Four strictures were obliterative and six were near-obliterative. Two patients had a history of prior urethroplasty. The length of the LMGs harvested ranged from 11 to 14 cm (mean, 12.8±1.03 cm). The preputial flaps available were from 1 to 1.5 cm in width (1.29±0.16 cm) and the desired length. Maximum urinary flow rate (Qmax) achieved ranged from 12 to 26 mL/s (mean, 20.46±3.71 mL/s) after 3 months. One patient needed a single direct visualized internal urethrotomy and another patient develop temporary superficial penile necrosis. The success rate was 90%. Conclusions: Long obliterative and near-obliterative penile and penobulbar urethral strictures can still be treated in circumcised patients using available preputial skin along with lingual mucosa with good outcomes.

Comparison of safety and efficacy of silodosin, solifenacin, tadalafil and their combinations in the treatment of double-J stent- related lower urinary system symptoms: A prospective randomized trial.

OBJECTIVE: To evaluate the efficacy and safety of silodosin, solifenacin, tadalafil and their combinations in reducing double J (DJ) stent-related symptoms (SRS). MATERIAL AND METHODS: A total of 335 patients who underwent DJ stenting and develop SRS at 1st week were randomized into eight groups. Ureteral stent symptom questionnaire (USSQ) and Quality of life (QOL) scores were noted in each group: Group A-Silodosin (8 mg OD)+ Solifenacin (10 mg OD)+ Tadalafil (5 mg OD), B - Silodosin 8 mg OD, C - Solifenacin 10 mg OD, D- Tadalafil 5 mg OD, E- Silodosin (8 mg OD) + Solifenacin (10 mg OD), F- Silodosin (8 mg 0D)+ Tadalafil (5 mg OD), G- Solifenacin (10 mg OD)+ Tadalafil (5 mg OD) and H-placebo. Analgesic (diclofenac 50 mg) was given as per requirement. All groups received the drugs for 14 days and again USSQ, QOL score with analgesic requirement were noted in each group. RESULTS: USSQ score was similar in all groups at 1st week but all groups (Groups A-G) led to significant decrease in USSQ score at 3rd week as compared to Group H with less requirement of analgesic. However when we compared groups with each other we found that mean USSQ score and analgesic requirement was favoring Group E as compared to other groups. Quality of life score was also best in Group E (mean 1.5) (p<0.05). CONCLUSION: Combination therapy with silodosin and solifenacin (group E) was effective for relieving SRS with improved quality of life and less requirement of analgesic than any other groups and should be considered in patients who develop SRS.

STONE score versus Guy's Stone Score - prospective comparative evaluation for success rate and complications in percutaneous nephrolithotomy.

PURPOSE: The aim of the current study was to compare Guy's score and STONE score in predicting the success and complication rate of percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: A total of 445 patients were included in the study between July 2015 and December 2016. The patients were given STONE score and Guy's Stone Score (GSS) grades based on CT scan done preoperatively and intra- and post-operative complications were graded using the modified Clavien grading system. The PCNL were done by a standard technique in prone positions. RESULTS: The success rate in our study was 86.29% and both the GSS and STONE score were significantly associated with a success rate of the procedure. Both the scoring systems correlated with operative time and postoperative hospital stay. Of the total cases, 102 patients (22.92%) experienced complications. A correlation between STONE score stratified into low, moderate, and high nephrolithometry score risk groups (low scores 4-5, moderate scores 6-8, high scores 9-13), and complication was also found (P = 0.04) but not between the GSS and complication rate (P = 0.054). CONCLUSION: Both GSS and STONE scores are equally effective in predicting success rate of the procedure.

Benign diaphragmatic neurilemmoma mimicking a left adrenal cyst.

Neurilemmomas are benign, slow growing, encapsulated nerve sheath tumor. These tumors arise from the schwann cells of neural crest. Neurilemmomas can manifest in various form according to site, extent and severity of involvement of organ. Diaphragmatic neurilemmomas are very unusual and even difficult to diagnose on preoperative imaging. We will report a case of 39 year old male, who presented with complaints of occasional left flank pain for one year and subsequently investigated, which showed left adrenal cyst with haemorrhagic fluid content. On the contrary, when surgical exploration of the lesion was done, it showed a cyst within the diaphragm, completely separated from left kidney and left adrenal with haemorrhagic content in situ. Histopathological examination of the lesion showed it to be a benign neurilemmoma with cystic degeneration. Post opearatively patient did well. We believe that this is the first case report, which is addressing such kind of initial manifestation of diaphragmatic neurilemmomas.

Role of oestrogen receptor-α and -ß in bladder tissue of patients with a clinical diagnosis of benign prostatic hyperplasia.

OBJECTIVES: To study the differential expression of oestrogen receptor (ER) subtypes in human urinary bladder tissue using immunohistochemistry (IHC) methods and to explore their correlation with various measures of lower urinary tract symptoms (LUTS). METHODS: In this prospective case-control study, the case group comprised 34 patients with bothersome LUTS who underwent transurethral resection of prostate (TURP), while the control group comprised 19 age-matched, otherwise healthy patients who underwent cystoscopy to investigate microscopic haematuria. Cystoscopy and bladder biopsy were performed in both groups. IHC evaluation of biopsy specimens was carried out for ER subtypes (ER-α and ER-ß) and for Ki 67 in semi-quantitative fashion. Correlations of receptors with various measures of benign prostatic hyperplasia (BPH)/LUTS were also assessed. RESULTS: Expression of ER-α (in both epithelial and stromas cells) was statistically significantly greater in the case group than in the control group, but ER-ß expression was not significantly different between the groups. Ki 67 expression was also significantly greater in the case group. Comparison of clinical variables according to receptor status showed that International Prostate Symptom Score (IPSS), post-void residual urine volume (PVR) and prostate volume were significantly associated with epithelial and stromal ER-α; however, ER-ß was associated only with PVR. CONCLUSION: We found significant correlation between bladder ER levels (specifically ER-α) and various clinical measures of BPH. We conclude that ER-α is the key mediator that could be responsible for various clinical measures of BPH/LUTS.

Video Endoscopic Inguinal Lymphadenectomy vs Open Inguinal Lymphadenectomy for Carcinoma Penis: Expanding Role and Comparison of Outcomes.

OBJECTIVE: To compare differences of morbidity profile, oncological yield, and efficacy between video endoscopic inguinal lymphadenectomy and open inguinal lymphadenectomy cases. MATERIALS AND METHODS: A total of 29 patients with proven squamous cell carcinoma of the penis were selected for inguinal lymphadenectomy from August 2013 to January 2017. Video endoscopic lymphadenectomy was performed on 1 limb and open inguinal lymphadenectomy was performed on the contralateral side. Relevant outcome data such as operative time, complication rate, number of lymph nodes removed, number of positive nodes, and recurrence during the follow-up period were collected, analyzed, and compared. RESULTS: The mean operative time was significantly longer for the video endoscopic inguinal lymphadenectomy group (mean = 162.83 minutes) as compared with the open group (mean = 92.35 minutes). However, the mean numbers of lymph nodes removed were 7.6 in the endoscopic group and 8.3 in the open group. Postoperative complications occurred in 10 limbs (34.48%) in the open group and in 3 limbs (10.34%) in the endoscopic group. In the follow-up period ranging from 7 to 28 (mean 14) months, 2 patients died because of either distant or visceral metastasis. CONCLUSION: The present study clearly outlines the fact that video endoscopic inguinal lymphadenectomy can deliver an equivalent lymph node yield similar to open inguinal lymphadenectomy with significantly less morbidity and is not affected by either the palpability or the number of palpable nodes. Thus, we believe that this minimally invasive technique can provide a prudent alternative for the management of the inguinal region in carcinoma of the penis.

Safety and efficacy of silodosin and tadalafil in ease of negotiation of large ureteroscope in the management of ureteral stone: A prosective randomized trial.

OBJECTIVE: To evaluate the safety and efficacy of silodosin and tadalafil in ease of negotiation of large size ureteroscope (8/9.8 Fr) in the management of ureteral stone. MATERIAL AND METHODS: Between June 2015 and May 2016, 86 patients presented with ureteral stone of size 6-15 mm were on consent randomly assigned to 1 of 3 outpatient treatment arms: silodosin (Group A), tadalafil (Group B), and placebo (Group C). After two weeks of therapy 67 patients underwent ureteroscopy, and ureteral orifice configuration, ureteroscopic negotiation, ureteral dilatation, operating time, procedural complication and drug related side effects were noted in each group. RESULTS: Ureteral negotiation was significantly better in Groups A (73.9%) and B (69.6%) as compared to Group C (38.1%) (p<0.01). Statistically significant difference was noted in the requirement for dilatation in Group C (71.4%) as compared to Groups A (26.1%) and B (39.1%) (p<0.01). Ureteral orifice was found to be more dilated in Groups A (69.6%) and B (60.9%) as compared to Group C (28.6%). Mean operating time was statistically lower in Groups A (35.2 min) and B (34.91 min) as compared to Group C (41.14 min) (p<0.01). CONCLUSION: Both silodosin and tadalafil not only relax ureteral smooth muscle but also help in forward propagation of large size ureteroscope (8/9.8 Fr) without any significant risk of adverse events.

Crossed Fused Ectopic Kidney: A Case Report.

Crossed fused ectopic kidney is an unusual congenital malformation of the urinary tract. This condition is usually identified in the autopsy specimen rather than in general clinical scenario. In this condition, both kidneys are located on one side of the midline and are fused with each other. This condition is generally asymptomatic and usually diagnosed as incidental finding. We came across a case of crossed fused left to right ectopia with inferior infusion with nephroptosis. Generally, in cases of crossed fused renal ectopia, one kidney is lower than the other one but in our report, both kidneys were present at the same level. Initially it was thought as cake kidney, but on careful inspection diagnosis of crossed fused left to right ectopia with inferior infusion was made. During workup of abdominal pain, this finding was detected with no gross abnormality except for a tiny calculus. After detailed discussion with the patient, regular follow up was done without any active intervention and during that period he remained clinically and radiologically stable. So in these conditions active intervention is not always mandatory and patient may remain asymptomatic without any intervention.

Prostatic Ductal Adenocarcinoma-A Rare Entity With Radiological Dilemma Demanding Endoscopic Biopsy.

This is a rare case of a prostatic ductal adenocarcinoma. A 75-year-old gentleman presented with complaints of lower urinary tract symptoms, constipation, and occasional hematuria. The clinical and radiological differentiations from other retroperitoneal soft cystic lesion were difficult, and fine needle aspiration cytology from the papillary solid components of the cyst was required to reach diagnosis. Transrectal ultrasound-guided biopsy was performed in view of the raised serum prostate-specific antigen (>100 ng/mL); however, the cyst was ruptured without yielding any tissue for biopsy. In such difficult situations, a cystourethroscopic view, biopsy of the cyst, and immunohistochemical analysis can help in diagnosing and confirming the prostatic ductal adenocarcinoma.

A Comparative Study of Antegrade Air Pyelogram and Retrograde Air Pyelogram for Initial Puncture Access during Percutaneous Nephrolithotomy.

INTRODUCTION: Access into the collecting system is considered to be the most critical step for Percutaneous Nephrolithotomy (PCNL). AIM: The present study provides a comparative view into antegrade air pyelography and retrograde air pyelography procedures for percutaneous renal access. MATERIALS AND METHODS: A cross-sectional study was conducted on 100 patients with radiopaque renal calculi indicated for PCNL procedure. These patients were randomly assigned to two groups namely antegrade air pyelogram group (Group I) and retrograde air pyelogram group (Group II). In antegrade air pyelogram group, the collecting system was delineated by targeting the renal stone using a 22 gauge spinal needle where the patients were in the prone position. In another group, the collecting system was delineated by retrograde air pyelogram under fluoroscopy guidance. The method of tract dilatation and stone extraction were the same in both groups for comparison of outcome and complication. RESULTS: The mean age of patients was 41.7±13 and 41.4±13.6 years in Group-I and Group-II respectively. The male to female ratio in Groups I and II was 35/15 (70.00%) and 38/12 (76.00%) respectively. In Group-I the average duration of access was 2.66±1.0 minutes after prone positioning whereas it was recorded to be 19.48±5.0 minutes in Group-II, after lithotomy followed by prone positioning of the patient. Duration of radiation exposure was almost similar in both groups. Additional procedural cost was significantly higher in Group II. CONCLUSION: Our study indicated that access for PCNL using antegrade air pyelogram can be a cost-effective and acceptable alternative to retrograde air pyelogram with decreased access time.

Xanthogranulomatous pyelonephritis presenting as a type IV renal cyst.

A 20-year-old woman presented to our outpatient clinic with a 5-week history of recurrent right lumbar back pain. Contrast-enhanced computed tomography scan showed a Bosniak class IV renal cyst. She was treated with radical nephrectomy. Histopathology revealed xanthogranulomatous pyelonephritis.

Unusual Presentation of Prostate Carcinoma: A Case Report.

Prostate cancer is a common cancer in elderly men and it frequently metastasizes to regional lymph nodes and sometimes to bone. Very rarely in some of the cases it also shows involvement of non-regional lymph nodes like supra-diaphragmatic lymph nodes. In our report, we present a 60-year-old male, initially misdiagnosed as Chronic Obstructive Pulmonary Disease (COPD) with cervical lymph node involvement may be due to infective region or inflammatory pathology, which was later found to have prostatic adenocarcinoma metastatic to supraclavicular lymph nodes. Very less case reports are present which have shown similar presentations. So we would like to highlight that prostatic carcinoma can be present in an atypical form also.
