Duodenal damage complicating percutaneous access to kidney.
CONTEXT: Since the first percutaneous nephrostomy performed by Goodwin in 1954, technical advances in accessing the kidneys via percutaneous puncture have increased the use of this procedure and thus the complications too. Among these complications, digestive tract damage is not common. DESIGN: Case report. CASE REPORT: We report a duodenal lesion that was corrected using surgical exploration and we touch on the therapeutic options, which may be conservative or interventionist. We chose conservative treatment, which has been approached in diverse manners in the literature. (+info)
Severe renal bleeding caused by a ruptured renal sheath: case report of a rare complication of percutaneous nephrolithotomy.
BACKGROUND: Percutaneous nephrolithotomy is a minimally invasive intervention for renal stone disease. Complications, which are rare and usually presented as case reports, are diversified as the utilization of the procedure is expanded. The procedure causes less blood loss and less morbidity when compared to open surgical procedures. Yet, there are some reports involving severe bleeding and relevant morbidity during surgery. These are usually related with the surgical technique or experience of the surgeon. Renal sheaths are designed to cause minimal trauma inside the kidney and, to our knowledge, there are no reports presenting the rupture of a sheath causing severe bleeding during the procedure. CASE REPORT: We present an adult patient who had severe bleeding during percutaneous nephrolithotomy due to parenchymal injury caused by a ruptured renal sheath. During retrieval, due probably to rough handling of the equipment, a piece of stone with serrated edges ruptured the tip of the sheath, and this tip caused damage inside the kidney. The operation was terminated and measures were taken to control bleeding. The patient was transfused with a total of 1600 ml of blood, and the stones were cleared in a second look operation. CONCLUSION: Although considered to be a minimally invasive procedure, some unexpected complications may arise during percutaneous nephrolithotomy. After being fragmanted, stone pieces may damage surgical equipment, causing acute and severe harm to the kidney. Surgeons must manipulate the equipment with fine and careful movements in order to prevent this situation. (+info)
Single session endoscopic management of intrinsic ureteropelvic junction obstruction and concomitant renal stone disease in a child: a case report.
BACKGROUND: Percutaneous nephrolithotomy is a well known therapeutic modality for stone diseases of childhood. Antegrade and retrograde endopyelotomies are also well defined options of treatment for secondary ureteropelvic junction obstruction. Yet there are few reports regarding endoscopic therapy of intrinsic ureteropelvic junction obstruction. To our knowledge, there exist only a few reports of endosurgical treatment of children with stone disease and with concomitant intrinsic ureteropelvic junction obstruction, in the literature. CASE PRESENTATION: We present the endoscopic management of stone disease and concomitant intrinsic ureteropelvic junction obstruction of a child in one session. CONCLUSION: Percutaneous nephrolithotomy and antegrade endopyelotomy is combined safely with successful outcome in a child. (+info)
Air embolism: diagnosis with single-photon emission tomography and successful hyperbaric oxygen therapy.
Venous air embolism may occur when the surgical field is above the level of the heart. We present a case of venous air embolism in a patient undergoing percutaneous nephrolithotripsy in the prone position and presenting with blindness and neurological deficits 8 h later. The clinical diagnosis of paradoxical air embolism was confirmed by early single-photon emission tomography (SPET), whereas magnetic resonance imaging including diffusion-weighted imaging (DW-MRI) was diagnostic only 30 h later. Hyperbaric oxygen therapy was successful. In this case, early DW-MRI scan was inconclusive, but a SPET study of the brain appeared to be useful in confirming the clinical diagnosis. Early hyperbaric oxygen was demonstrated to be a successful therapy. (+info)
Nonvascular interventions of the urinary tract.
Nonvascular intervention of the urinary tract is a well-established uroradiologic subspecialty, which is more important for avoiding invasive open surgery in the age of rising demand about the value of less invasive treatment. Various kinds of nonvascular intervention are recently performed under image-guidance and are as follows: percutaneous nephrostomy, percutaneous nephrostolithotomy, percutaneous dilatation of the urinary tract, sclerotherapy for renal cysts, percutaneous catheter drainage, percutaneous foreign body retrieval and biopsy. Percutaneous nephrostomy is a basic technique to provide a direct access to urinary tract, which makes it possible to perform other interventional procedures. Although nonvascular intervention may produce some complications, it is generally considered to be less invasive than open surgery and has advantages such as short hospital stay, early return to normal life and therefore economic savings. This review is described to help clinicians easily understand the procedures, indications, techniques, and complications with figures of cases the authors experienced. (+info)
Day care percutaneous renal surgery--is this viable?
Pros and cons of Percutaneous Nephrolithotripsy (PCNL) versus Extracorporeal Shockwave Lithotripsy (ESWL) have often been highlighted when one discusses on the management of renal stones. An oft quoted point is that PCNL entails a prolonged hospital stay whereas ESWL sessions are day surgical in nature. However, PCNL has superior stone clearance rate as compared to ESWL especially for lower pole stones. In addition, PCNL is more suitable for large bulk stones and when ancillary procedures are required e.g. endopyelotomy. The first 50 cases of successful tubeless PCNL were reported by Bellman et al in 1997. The remarkable recovery of patients in their series encouraged them to employ this technique as their technique of choice for the majority of their cases. A similar technique was employed on endopyelotomy by Liang et al and they concluded that this was a safe, less morbid and effective technique. We report our first case of tubeless PCNL. (+info)
Management of lithiasis in pelvic kidney through laparoscopy-guided percutaneous transperitoneal nephrolithotripsy.
We report the case of a patient with pain and an abdominal palpable mass whose tests showed a left pelvic kidney with a 1.5-cm stone in the renal pelvis. We describe the successful management through videolaparoscopy-guided percutaneous transperitoneal nephrolithotripsy, stressing that this method is a therapeutic option in such cases. (+info)
The role of percutaneous nephrostomy in malignant ureteric obstruction.
OBJECTIVES: Uraemia as a result of malignant ureteric obstruction is a recognised event in those with advanced malignancy, usually of pelvic origin, which, if left untreated, is quickly a terminal event. Palliative decompression of the obstructed urinary system, either by percutaneous nephrostomy (PCN), ureteric stent or a combination of both is a recognised method of improving renal function, with presumed low morbidity. The aims of the study were to assess whether PCN placement in malignant ureteric obstruction provided any additional survival benefit or patient morbidity. PATIENTS AND METHODS: The case notes of 32 patients with a mean age of 68.1 years (16 male, 16 female) who underwent PCN drainage for malignant ureteric obstruction were retrospectively analysed. Data on the site of primary malignancy, mode of presentation, improvement in renal function, median survival, conversion to internal ureteric stents and intervention-related complications were collected for analysis. RESULTS: The median survival following PCN insertion was 87 days and was unrelated to the patient's age and renal function. Those patients with primary underlying gynaecological malignancies appeared to survive almost 4 times as long as those with underlying primary bladder cancer. Renal function took a mean of 16.8 days to reach a nadir. Almost 79% of patients were able to be discharged from hospital--each patient, however, being re-admitted back to hospital on average 1.6 times prior to their death through PCN or internal ureteric stent related events. Retrospective "useful quality of life" was seen in less than half of the patient cohort. CONCLUSIONS: In the presence of malignant ureteric obstruction, palliative percutaneous urinary diversion may be performed and is effective in improving renal function. However, long-term survival is limited and should, therefore, be performed only when the views and wishes of the patient and carers are taken into account and if there is a definitive treatment plan available for the patient as quality of life can be suboptimal.
