RESUMO

CONTEXT: Long-term outcome following a laparoscopic reconstruction of ureteral strictures (US) involving solitary renal units (SRU) are scarcely reported. AIMS: The aim was to report short-term (1 year) and long-term (5 years) outcomes following a laparoscopic reconstruction of US in a solitary kidney. SETTINGS AND DESIGN: Retrospective. MATERIALS AND METHODS: Records of patients operated for similar scenarios between January 2004 and January 2014 were evaluated. Clinical, biochemical and radiological profile were noted. Operative and post-operative profile were recorded. Follow-ups were scheduled at regular intervals (3 months post-procedure, 6 monthly for 2 years and yearly thereafter. Imaging was repeated at yearly intervals). Outcome was assessed by comparing pre-operative and post-operative clinical, biochemical, and radiological parameters. STATISTICAL ANALYSIS USED: SAS software 9.2 version. A P < 0.05 was inferred as statistically significant. RESULTS: Seven patients underwent a laparoscopic reconstruction. Stricture location was upper ureter (n = 1), mid ureter (n = 2), lower ureter (n = 4). Surgeries performed were ureteroureterostomy, Boari flap ureteroneocystostomy and ureteroneocystostomy with psoas hitch. Four patients reported prior contralateral nephrectomy. Three patients underwent prior endoscopic correction. Four patients presented with elevated serum creatinine (>1.4 mg/dl). Till last follow-up, improvement in symptomatology and improvement or stabilisation of serum creatinine was perceived in all. Ureteral patency with resolution of hydronephrosis was observed in five patients at 1 year follow-up. Two patients revealed ureteral patency with persistence of hydronephrosis. Clinical, biochemical and radiological outcomes were maintained till long-term follow-up. CONCLUSION: Laparoscopic reconstruction of US in SRU offers impressive short- and long-term outcome.

RESUMO

CONTEXT: Pure laparoscopic nephrectomy in patients with ADPKD (autosomal dominant polycystic kidney disease) and ESRD (end-stage renal disease) on MHD (maintenance hemodialysis) is challenging with high incidence of complications. Limited experiences from India has been reported in these scenarios. AIMS: To present a 10-year single surgeon experience from India in laparoscopic nephrectomy in autosomal dominant polycystic kidneys (ADPKD) and end-stage renal disease (ESRD) on maintenance hemodialysis (MHD). SETTINGS AND DESIGN: Retrospective. MATERIALS AND METHODS: Retrospective analysis of records of similar subset of patients who were offered laparoscopic nephrectomy between 2003 and 2012. Preoperative, operative and postoperative parameters were recorded. Few technical modifications were adopted over the years. Patients were sub-classified into two groups (Group I: 2003-2006, Group II: 2007-2012) based on surgical technique. STATISTICAL ANALYSIS USED: SAS software 9.1 version. RESULTS: 75 patients (84 renal units, Group I: 31, Group II: 53) were included in this analysis. Unilateral procedure was performed in 66 and bilateral staged or simultaneous procedure in 9. Despite larger kidneys in Group II (mean longitudinal renal length 25.7 ± 3.4 vs 17.5 ± 2.7 centimeters, P <0.001), improved operative and postoperative profile were noted in Group II in several parameters-mean total operative time (205 ± 11.5 vs 310 ± 15.3 min, P = 0.00), time for specimen retrieval (30.5 ± 3.5 vs 45 ± 4.1 min, P = 0.02), postprocedure drop in hemoglobin (1.1 ± 0.1 vs 2.27 ± 0.03 grams/deciliter, P = 0.00). Conversion rates, intraoperative and postoperative events were also considerably less in Group II. CONCLUSIONS: Despite existence of comorbidities and technical difficulties, laparoscopic nephrectomy in patients with ADPKD with ESRD and on MHD is a feasible option. Technical modifications with increasing surgeon's experience allows successful conductance of this approach in more complex cases with better outcome.

RESUMO

Laparoscopic adrenalectomy is the standard of care for management of adrenal neoplasms. However, large sized adrenal lesions are considered as relative contraindication for laparoscopic extirpation. We report laparoscopic excision of giant ganglioneuroma of adrenal gland in a 33-year-old female patient. Patient was presented with left loin pain of 2 months duration. Computed tomography (CT) scan was suggestive of non-enhancing left suprarenal mass measuring 17 × 10 cm. Preoperative endocrine evaluation ruled out functional adrenal tumor. Patient underwent transperitoneal excision of suprarenal mass. The lesion could be completely extirpated laparoscopically. Duration of surgery was 250 minutes. Estimated blood loss was 230 milliliters. Specimen was extracted through pfannenstiel incision. No significant intraoperative or postoperative happenings were recorded. Microscopic features were suggestive of ganglioneuroma of adrenal gland.

RESUMO

Immune cells employ diverse mechanisms for host defense. Macrophages, in response to TLR activation, assemble aggresome-like induced structures (ALIS). Our group has shown TLR4-signaling transcriptionally upregulates p62/sequestome1, which assembles ALIS. We have demonstrated that TLR4-mediated autophagy is, in fact, selective-autophagy of ALIS. We hypothesize that TLR-mediated autophagy and ALIS contribute to host-defense. Here we show that ALIS are assembled in macrophages upon exposure to different bacteria. These structures are associated with pathogen-containing phagosomes. Importantly, we present evidence of increased bacterial burden, where ALIS assembly is prevented with p62-specific siRNA. We have employed 3D-super-resolution structured illumination microscopy (3D-SR-SIM) and mass-spectrometric (MS) analyses to gain insight into the assembly of ALIS. Ultra-structural analyses of known constituents of ALIS (p62, ubiquitin, LC3) reveal that ALIS are organized structures with distinct patterns of alignment. Furthermore, MS-analyses of ALIS identified, among others, several proteins of known antimicrobial properties. We have validated MS data by testing the association of some of these molecules (Bst2, IFITM2, IFITM3) with ALIS and the phagocytosed-bacteria. We surmise that AMPs enrichment in ALIS leads to their delivery to bacteria-containing phagosomes and restricts the bacteria. Our findings in this paper support hitherto unknown functions of ALIS in host-defense.

RESUMO

Adrenal oncocytomas are rare tumors that are mostly benign and non-functional although they may be hormonally active and can exhibit a borderline or malignant potential. We present a case of a 40-year-old female patient with known hypertension who presented with abdominal discomfort. Radiologic investigations showed a large mass on the left adrenal gland. In the hormonal study, an aldosterone-secreting tumor was identified. After laparoscopic resection, the histological assessment of the 12-cm mass showed an oncocytic neoplasm with borderline characteristics. The laboratory results returned to normal and the hypertensive disease improved. The patient was doing well after 14 months of follow-up. This is the seventh documented case of aldosterone-secreting oncocytoma, the first borderline tumor of this type, and the largest reported tumor so far.

RESUMO

Mycoplasma hominis is one of the pathogenic organisms that may cause prostatitis with the development of a prostatic abscess in very rare cases. A 57-year-old man presented with lower urinary tract symptoms and low-grade fever. The transabdominal ultrasonography showed prostate enlargement suggesting acute prostatitis. The patient was started on empiric antibacterial therapy with fluoroquinolones. The urine and semen cultures showed no bacterial growth. A few days later, the patient presented again with symptoms progression and acute urinary retention. The transrectal ultrasound revealed diffuse calcifications and intraprostatic fluids. The computed tomography of the abdomen and pelvis showed a large abscess in the prostate with a periprostatic inflammatory reaction. While all bacterial cultures were negative, the multiplex polymerase chain reaction (PCR) test revealed a Mycoplasma hominis infection. The patient was managed with transurethral drainage. After six months of follow-up, the patient was free of symptoms and the repeat PCR study confirmed clearance of the Mycoplasma infection.

RESUMO

OBJECTIVES: The widespread use of ultrasonography for the investigation of common urological conditions, such as infertility or pain, has resulted in an increased incidence of incidental non-palpable testicular masses. The majority of these are expected to be benign therefore a conservative approach, either active monitoring or organsparing approach, is recommended. However, there are no clinical or radiological parameters which define the exact nature of such lesions and optimal patient selection criteria are lacking. In this comprehensive review we discuss the significance of incidental, small testicular masses (STMs) and the role of organ-sparing approach in the management of these lesions. MATERIALS AND METHODS: A non-systematic search was performed using PubMed to identify articles that covered the following topics; clinical implications at diagnosis, role of imaging in identifying the malignant capabilities of a lesion, role of surgery and the final pathology. RESULTS: Incidental STMs are routinely identified following ultrasound examination of infertile men. STMs usually measure a few millimeters in size and the majority of these are benign. Therefore, strict follow up or an organ-sparing approach, with utilisation of frozen section analysis (FSA), is favored for STMs. FSA has a high correlation with final pathology and prevents unnecessary orchidectomies. Advances in imaging, namely ultrasound and magnetic resonance imaging may provide enhanced assessment of STMs and guidance intraoperatively. CONCLUSIONS: The optimal approach is not well defined and there is no specific clinical parameter that can predict the nature of STMs. The increasing incidence of small, benign testicular masses has resulted in the development of organ-sparing surgery to investigate and manage these lesions. Organ-sparing surgery has been shown to be practical and carries excellent oncological outcomes.

RESUMO

OBJECTIVE: To evaluate spectrum and resistance rates to antibacterial agents in causative pathogens of bacterial prostatitis in patients from Southern Europe, the Middle East, and Africa. MATERIALS: 1027 isolates from cultures of urine or expressed prostatic secretion, post-massage urine or seminal fluid, or urethral samples were considered. RESULTS: Escherichia coli (32%) and Enterococcus spp. (21%) were the most common isolates. Other Gram-negative, Gram-positive, and atypical pathogens accounted for 22%, 20%, and 5%, respectively. Resistance was <15% for piperacillin/tazobactam and carbapenems (both Gram-negative and -positive pathogens); <5% for glycopeptides against Gram-positive; 7%, 14%, and 20% for aminoglycosides, fosfomycin, and macrolides against Gram-negative pathogens, respectively; 10% for amoxicillin/clavulanate against Gram-positive pathogens; <20% for cephalosporins and fluoroquinolones against to Gram-negative pathogens (higher against Gram-positive pathogens); none for macrolides against atypical pathogens, but 20% and 27% for fluoroquinolones and tetracyclines. In West Africa, the resistance rates were generally higher, although the highest rates for ampicillin, cephalosporins, and fluoroquinolones were observed in the Gulf area. Lower rates were observed in Southeastern Europe. CONCLUSIONS: Resistance to antibiotics is a health problem requiring local health authorities to combat this phenomenon. Knowledge of the spectrum of pathogens and antibiotic resistance rates is crucial to assess local guidelines for the treatment of prostatitis.

RESUMO

Synovial sarcoma (SS) is a tumor of the soft tissues with a unique chromosomal translocation t(X;18)(p11.2;q11.2) that can be detected by polymerase chain reaction in tissue homogenates. Here we present a case of a 20-year-old female presenting PSS of the left kidney with caval thrombus. The diagnosis was corroborated by reverse transcription polymerase chain reaction (RT-PCR). Similar cases of PSS of kidney with tumor extension in the inferior vena cava are extremely rare and to date, approximately three cases have been reported in the literature.

RESUMO

Xanthogranulomatous pyelonephritis (XGPN) is an atypical long-term pyelonephritis with destruction of renal parenchyma and a long-term inflammatory infiltrate of macrophages. Reported presentations of transitional cell carcinoma (TCC) are different. A 73-year-old woman presented with loin pain, prostration, and fever. Computed tomography scan revealed poor cortical enhancement of the kidney, but some of the images bore resemblance to the characteristic "bear's paw" sign, consistent with XGPN with a 7-cm perinephric collection. She was provisionally diagnosed as severe acute pyelonephritis, possibly XGPN, with abscess. In view of the poor clinical condition, decision was made to perform nephrectomy. Histology revealed a G3pT4 high grade TCC with perineural and vascular invasion and reactive xanthogranulomatous inflammatory response. There are few reports of concomitant XGPN and TCC affecting the kidney. However, there has not been any mention of XGPN and TCC presenting as acute pyelonephritis and perinephric abscess so far.

RESUMO

Background: Memokath 051™ stents are increasingly used for management of benign and malignant ureteral strictures refractory to management with single or tandem polymeric Double-J ureteral stents. Migration, encrustation, and difficulty in extraction during stent exchange are the chief problems reported so far with these thermoexpandable metallic stents. We report an unusual complication of ureteroexternal iliac artery fistula (UEAF) caused by Memokath stent inserted for radiation-induced ureteral stricture. Case Presentation: A 71-year-old male with history of colorectal cancer (underwent extirpative surgery + chemoradiotherapy) and subsequently radiation-induced ureteral stricture had bilateral Memokath ureteral stents inserted. Three months later, he presented with sepsis and hemodynamic instability secondary to UEAF, confirmed on angiography. A covered vascular stent was inserted as an immediate management. Conclusion: Memokath stent insertion in radiation-induced ureteral strictures may be associated with an increased risk of erosion and the rare potential complication of UEAF. This potential risk needs to be considered in the overall setting of such strictures and the difficulty in treating them. Prompt imaging (angiography) and placement of an endovascular stent are the ideal immediate options in such cases.

RESUMO

Urolithiasis in pregnancy is a major health concern and can potentially affect the well-being of both mother and foetus. Management of this condition often entails simultaneous multidisciplinary involvement of obstetrician, radiologist and urologist. Additionally, adverse effects with usage of anaesthesia, radiation, medications and surgery on mother and foetus, limit utilisation of the full armamentarium of diagnostic and therapeutic modalities that are commonly used in non-pregnant women. This review was conducted using an electronic literature search of peer reviewed journal articles. Clinical studies were identified in the bibliographic database- PubMed (Medline), Ovid and eMedicine(WebMD) using the keywords: hydronephrosis, urolithiasis, kidney stone, urinary tract infection, pregnancy and ultrasound, incidence and epidemiology of renal stones.

RESUMO

INTRODUCTION: An abdominoscrotal hydrocele (ASH) consists of a large inguinoscrotal hydrocele which communicates in an hour glass fashion with a large "intraabdominal component". Mostly affects single testis but very rarely can present bilaterally. PRESENTATION OF CASE: We are presenting here a young 25 year old patient with large right sided scrotal swelling encroaching over lower abdomen. Clinically it was abdominoscrotal hydrocele which was confirmed with CT abdomen and later on subjected for surgery. DISCUSSION: Abdominoscrotal hydrocele is rarest type of hydrocele; first described by Dupuytren. The etiology of ASH is unknown; however, different theories have been described in literature to explain the pathogenesis. Diagnosis of ASH is done by clinical examination and is confirmed by radiological examination. Though ultrasonography is the first choice, in few selected cases contrast enhanced computerized tomography or magnetic resonant imaging may be helpful for more anatomical delineation. It may present with various complications secondary to pressure exerted by the components of the ASH. Surgical excision of the sac is the only definitive treatment option. There is no role of conservative treatment. Sometimes, decompression of the cyst needed to ease the dissection of the sac. CONCLUSION: Abdominoscrotal hydrocele differential should be considered while dealing with large lower abdominal swelling along with scrotal swelling.

RESUMO

OBJECTIVE: The aim was to analyze the operative, postoperative and functional outcome of laparoscopic management of previously failed pyeloplasty and to compare operative and postoperative outcome with laparoscopic pyeloplasty for primary ureteropelvic junction obstruction (UPJO). MATERIALS AND METHODS: All patients who underwent laparoscopic management for previously failed dismembered pyeloplasty were analyzed in this study. Detailed clinical and imaging evaluation was performed. Transperitoneal approach was followed to repair the recurrent UPJO. Operative, postoperative, and follow-up functional details were recorded. Operative and postoperative outcomes of laparoscopic redo pyeloplasty were compared with that of laparoscopic primary pyeloplasty. RESULTS: A total of 16 patients were managed with laparoscopic approach for previously failed pyeloplasty. Primary surgical approach for dismembered pyeloplasty was open in 11, laparoscopy in four patients and robotic assisted in one patient. Fifteen were treated with redo pyeloplasty and one with ureterocalicostomy. Mean operative time was 191.25 ± 24.99 min, mean duration of hospital stay was 3.2 ± 0.45 days and mean follow-up duration was 29.9 ± 18.5 months with success rate of 93.3%. Operative time was significantly prolonged with redo pyeloplasty group compared with primary pyeloplasty group (191.25 ± 24.99 vs. 145 ± 22.89, P = 0.0001). CONCLUSION: Laparoscopic redo pyeloplasty is a viable option with a satisfactory outcome and less morbidity.

RESUMO

INTRODUCTION: We studied the feasibility of ex-vivo nephron-sparing surgery and autotransplantation for complex renal tumours. We also studied the role of laparoscopy in these situations. METHODS: All patients who underwent renal autotransplantation for renal tumour at our centre were included in this retrospective study. Patient profiles were recorded in detail. Operative and postoperative details were also recorded. RESULTS: Our series includes 3 patients. Two patients had complex renal cell carcinoma and 1 patient had bilateral large angiomyolipoma. In first 2 patients, laparoscopic approach was used for nephrectomy. Operative time for case 1, 2 and 3 was 5.5, 4.5, 8 (right side) and 6 (left side) hours, respectively. Cold ischemia time was 110, 90, 150 and 125 minutes, respectively. One patient required temporary postoperative hemodialysis. CONCLUSION: Ex-vivo nephron-sparing surgery and autotransplantation still remain a viable option for complex renal tumours. It offers satisfactory renal functional outcome with acceptable morbidity. The laparoscopic approach should be used whenever possible to reduce morbidity.

RESUMO

PURPOSE: To narrate our experience with laparoscopic reconstruction of obstructive megaureter (MGU) and assess the intermediate-term outcome achieved. PATIENTS AND METHODS: Patients were evaluated in detail including presenting complaints, biochemical profile, and imaging (ultrasonography [USG], diuretic renography [DR], magnetic resonance urography [MRU], and voiding cystourethrography [VCUG]). All patients with a diagnosis of obstructive MGU and salvageable renal unit were offered laparoscopic reconstruction. The standard laparoscopic exercise included ureteral adhesiolysis until the pathologic segment, dismemberment, straightening of the lower ureter, excisional tapering, and a nonrefluxing ureteroneocystostomy. Operative and postoperative parameters were recorded. Patients were evaluated postprocedure on a 3-month schedule. Follow-up imaging included USG and VCUG at 6 months and 1 year postprocedure and then at yearly intervals. MRU and DR were repeated at 1 year postprocedure. RESULTS: Twelve patients (13 units-11 unilateral, and 1 bilateral) underwent laparoscopic tailoring and reimplantation for obstructive MGU. Mean age was 98.6 months. All patients were male. Mean body mass index was 17.69 kg/m(2). Presenting complaints were flank pain (n=8) and recurrent urinary infection (n=12). All procedures were completed via a laparoscopic approach. Mean operation duration was 183 minutes, and mean blood loss was 75 mL. Mean duration of hospital stay was 2.1 days. No major intraoperative or postoperative happenings were recorded. All patients were asymptomatic at follow-up with stable renal profile. Follow-up MRU revealed a decrease in ureteral and upper tract dilatation with satisfactory drainage in all. Follow-up VCUG demonstrated grade I vesicoureteral reflux in one patient. Eight patients completed 3-year follow-up with a satisfactory outcome. CONCLUSION: Laparoscopic reconstruction of obstructive MGU offers satisfactory immediate- and intermediate-term outcome without undue prolonged morbidity.

RESUMO

OBJECTIVE: To compare the operative outcome, morbidity profile, and functional outcome after transperitoneal laparoscopic dismembered pyeloplasty for ureteropelvic junction obstruction in unusual circumstances (intrinsic pathology in anomalous kidneys or unusual extrinsic pathologies; group 1) to the outcome after this procedure in familiar pathologies (normally located kidneys with intrinsic dysfunctional segment or extrinsic compression due to a crossing vessel; group 2). METHODS: The patients were evaluated in detail. All patients underwent transperitoneal laparoscopic dismembered pyeloplasty. The operative and postoperative parameters were recorded. Patients were followed up after the procedure on a 3-month protocol. Imaging was repeated at 1 year. No intervention during the follow-up period (ie, nephrostomy, ureteral stenting, or redo pyeloplasty) and improvement in the hydronephrosis grade and diuretic renogram parameters was interpreted as procedural success. The operative, postoperative, and follow-up parameters in the 2 groups were compared. RESULTS: Group 1 included 17 patients with intrinsic pathologic features and renal anomalies with ureteropelvic junction obstruction due to unusual extrinsic pathology. All procedures were successfully completed with the laparoscopic approach. A significant difference was noted in the mean operative duration (group 1, 196.9 ± 10.3 minutes; group 2, 125.44 minutes, P = .00). The other operative and postoperative parameters were comparable. No significant operative or postoperative events were noted. A total of 14 patients (group 1) completed the 1-year follow-up protocol. The success rate was 92.9% (13 of 14) in group 1 and 97.9% (44 of 45) in group 2 (P = .42). CONCLUSION: The procedural duration for laparoscopic dismembered pyeloplasty in unusual circumstances is longer than in familiar pathologies. However, the morbidity profile and functional outcome in these 2 scenarios were comparable.

RESUMO

A retrocaval ureter is a rare congenital cause of upper ureteric obstruction that results from entrapment of the upper ureter by the inferior vena cava (IVC) as it courses posterior to the cava. We report an interesting scenario of upper ureteric obstruction secondary to entrapment between twin segments of IVC.

RESUMO

Double-J stents that are inserted to span the ureterovesical anastomosis at ureteoneocystostomy may be associated with problems such as coiling or migration. An unusual occurrence of retroperitoneal migration of a Double-J stent after bilateral open ureteroneocystostomy is reported. The migrated stents were retrieved laparoscopically with construction of a laparoscopic ureteroneocystostomy.

RESUMO

CONTEXT: Influence of timing of repair on outcome following laparoscopic reconstruction of lower ureteric strictures AIMS: To assess the influence of timing of repair on outcome following laparoscopic reconstruction of lower ureteric strictures in our adult patient population. SETTINGS AND DESIGN: Single surgeon operative experience in two institutes. Retrospective analysis. MATERIALS AND METHODS: All patients were worked up in detail. All patients underwent cystoscopy and retrograde pyelography prior to laparoscopic approach. Patients were categorised into two groups: early repair (within seven days of inciting event) and delayed repair (after two weeks). Operative parameters and postoperative events were recorded. Postprocedure all patients were evaluated three monthly. Follow-up imaging was ordered at six months postoperatively. Improvement in renal function, resolution of hydronephrosis and unhindered drainage of contrast through the reconstructed unit on follow-up imaging was interpreted as a satisfactory outcome. STATISTICAL ANALYSIS USED: Mean, standard deviation, equal variance t test, Mann Whitney Z test, Aspin-Welch unequal variance t test. RESULTS: Thirty-six patients (37 units, 36 unilateral and 1 simultaneous bilateral) underwent laparoscopic ureteral reconstruction of lower ureteric stricture following iatrogenic injury - 21 early repair (Group I) and 15 delayed repair (Group II). All patients were hemodynamically stable at presentation. Early repair was more technically demanding with increased operation duration. There was no difference in blood loss, operative complications, postoperative parameters, or longterm outcome. CONCLUSIONS: In hemodynamically stable patients, laparoscopic repair of iatrogenically induced lower ureteric strictures can be conveniently undertaken without undue delay from the inciting event. Compared to delayed repairs, the procedure is technically more demanding but morbidity incurred and outcome is at par.
